Introduction

Today, organisations are confronted with numerous environmental challenges and pressures. In the hospitality sector, these encompass rising demands for sustainable practices, energy efficiency, and waste reduction1. Hotels and other hospitality businesses must adapt to regulatory changes, rising consumer expectations for eco-friendly services, and the need to reduce their carbon footprint2. Recognizing the importance of proactively addressing environmental challenges is essential for hospitality organizations to ensure long-term sustainability, resilience, and success in a rapidly changing world3,4. By adopting eco-friendly practices, embedding sustainability into operations and supply chains, and fostering a corporate culture that prioritizes environmental stewardship, hospitality organizations can significantly address environmental concerns5,6. The effectiveness of an organization’s environmental strategy extends beyond its policies and procedures to influence employees’ attitudes and behaviours toward organizational green innovation7. However, research suggests that leadership style plays a crucial role in green innovation, in addition to organizational strategy8. Thus, fostering a culture of green innovation within an organization, driven by strategic initiatives and leadership practices, can lead to more meaningful and impactful sustainability outcomes9,10.

The relationship between leadership and green innovation has been widely studied, yet many of these studies exhibit notable shortcomings. Previous studies have enhanced our understanding of the factors that promote green innovation, including transformational leadership Singh et al.11, responsible leadership Liao and Zhang12, environmentally-specific servant leadership Aboramadan et al.13, and green, inclusive leadership14. There is a significant gap in understanding the influence of additional factors on green innovation. Significantly, research into the connection between ecocentric leadership and employees’ green innovation is limited. Hence, this study aims to fill the existing literature gap by investigating the influence of ecocentric leadership on organizational green innovation. Ecocentric leadership embraces a proactive and dedicated approach, prioritizing environmental principles as the cornerstone of a company’s values and practices15. These leadership approaches prioritize environmental considerations, placing ecological responsibility at the forefront. They readily fit in with research on business environmental efficiency, ecological responsibility, and environmentally conscious behavior16. This choice was appropriate given our research objective of analysing the influence of ecocentric leadership on organisational green innovation.

Another aspect of this gap pertains to the examination of underlying mechanisms. In our study, we incorporated three variables green knowledge sharing, green ambidexterity, and technological orientation to elucidate their role in influencing the relationship between ecocentric leadership and organizational green innovation. Eco-centric leaders emphasize environmental principles and goals to create a culture of sustainability inside the organization17. This culture encourages employees to share knowledge and information about green practices and initiatives. When employees share knowledge about environmentally sustainable practices and innovations, they explore new green possibilities and improve the organization’s capacity to capitalize on its current green skills15. This knowledge-sharing facilitates the development of green ambidexterity within the organization18. Green ambidexterity enables an organization to simultaneously optimize its current green initiatives and explore new avenues for green innovation and sustainable outcomes19. This balanced approach to sustainability fosters a culture of continuous improvement and innovation, ultimately leading to enhanced organizational green innovation20.

Furthermore, this study examines the moderating role of technological orientation—a managerial technique involving technology in all aspects of a company’s operations21. By emphasizing environmental values and goals17, eco-centric leaders tend to prioritize the adoption and usage of technology, i.e., technological orientation to support green initiatives within the organization22. The ecocentric leadership visionary approach encourages the integration of technological solutions for environmental sustainability23. This enhances our understanding of how eco-centric leaders can incentivize employees to engage in environmentally friendly behaviors and share knowledge, ultimately developing successful interventions and regulations to promote green innovation. This study utilized social exchange theory to further our understanding of the study model.

All of the above concepts led us to suggest the following research questions: (1) Does ecocentric leadership promote organizational green innovation? (2) Can employee green knowledge sharing and green ambidexterity serve as an underlying mechanism linking ecocentric leadership to organizational green innovation? (3) Does technological orientation moderate the direct path between ecocentric leadership and employees’ green knowledge-sharing? (4) Does technological orientation buffer the mediated path between ecocentric leadership and organizational green innovation via green knowledge sharing?

This study makes several significant contributions to the literature. First, it reveals how ecocentric leadership fosters organisational green innovation through the sequential mediation of green knowledge sharing and green ambidexterity, providing a deeper understanding of the pathways to sustainability. Second, it highlights the crucial moderating role of technological orientation in enhancing the relationship between ecocentric leadership and green innovation, providing new insights into how technology can support eco-friendly practices. Third, it presents actionable strategies for organisations, particularly in the hospitality sector, to promote sustainable innovation by cultivating ecocentric leadership, enhancing knowledge sharing, and leveraging technological advancements. Lastly, by integrating social exchange theory and exploring these interconnected relationships, the study enriches the literature on leadership and sustainability, providing a comprehensive framework for future research, as shown in Fig. 1.

Theoretical foundation and hypotheses development

Social exchange theory

Social exchange theory24 provides an empirical basis for analyzing the dynamics of connections and interactions within organizations and the exchange of resources between leaders and individuals. Ecocentric leadership, which emphasizes environmental values and goals, can be viewed as a form of social exchange in which leaders provide support and incentives for environmentally sustainable behavior among employees25. In return, employees reciprocate by sharing green knowledge and exchanging information and ideas related to sustainable practices within the organization. This knowledge exchange fosters mutual trust and reciprocity among employees and leaders26. Moreover, green knowledge sharing contributes to the development of green ambidexterity within organizations. Employees exchange knowledge, resources, and assistance to utilize current green capabilities while exploring new green prospects20,27. As employees exploit and explore green initiatives, they exchange resources and collaborate to generate innovative solutions to environmental challenges. This collaborative exchange of ideas and efforts enhances an organization’s capacity for green innovation21.

Key constructs

Ecocentric leadership

Ecocentric leadership is a leadership style that refers to a sustainability-oriented paradigm prioritizing ecological welfare in leadership decisions, emphasizing the balance between human endeavors and the natural environment17,26. In contrast to conventional anthropocentric paradigms, it advocates for environmental stewardship, long-term sustainability, and ethical accountability in resource utilization28,29. Uddin et al.17determined that such leaders frequently exhibit transformational attributes and emphasize ecological principles. Hay23 underscored the internal integration of employees with environmental learning considerations into corporate activities. Similarly, research on the sustaincentric worldview presents ecocentric perspectives in leadership30. Biswas et al.26 advocated for a shift from ego-centric to eco-centric leadership to achieve sustainability. Literature supported this notion by promoting profound leadership grounded in ecological humility31. This leadership approach encourages systemic thinking and a commitment to intergenerational equality. Ecocentric leadership represents a rising demand for responsible and sustainable management within enterprises.

Green knowledge sharing

Green knowledge sharing involves spreading environmentally relevant information, ideas, and practices among employees32,33. It involves sharing information about green technologies, environmental regulations, sustainable practices, and ecological awareness to enhance collective environmental performance. This approach promotes environmental education and innovation through collaboration and a shared commitment to sustainability. Research has confirmed that spreading green knowledge is essential for fostering a culture of sustainability in businesses and enhancing green innovation performance34. It enhances employees’ environmental awareness and promotes the integration of sustainable practices into daily routine operations. Shafait and Huang35 argue that the dissemination of green knowledge positively influences green innovation and organizational effectiveness, sustainability. Consequently, green knowledge exchange serves as a strategic tool for organizations aiming to reduce environmental impact, supporting organizational green innovation while maintaining competitiveness in the green economy.

Green ambidexterity

Green ambidexterity refers to an organization’s ability to simultaneously engage in two complementary yet distinct green innovation strategies: green exploration (the development of novel, environmentally sustainable products, technologies, or processes) and green exploitation (the enhancement and refinement of existing green practices and resources)36,37. This approach competence enables organizations to balance long-term environmental innovation with short-term efficiency in sustainability initiatives. Green ambidexterity enables organizations to be both adaptive and efficient in addressing environmental concerns, and focuses on the organizational environmental goal38. Research indicates that enterprises exhibiting robust green ambidexterity are better positioned to achieve sustainable competitive advantage and improve environmental outcomes performance36. Shehzad et al.39 suggests that green ambidexterity strengthens green dynamic capabilities and boosts organizational green performance. It combines strategic flexibility with a strong ecological focus, enabling firms to address market and regulatory demands for sustainability.

Technological orientation

Technological orientation refers to an organization’s strategic focus on adopting, developing, and integrating advanced technologies to enhance products, services, and processes40. It demonstrates a company’s commitment to innovation, technical expertise, and continuous improvement through the use of new technology41. Organizations that have a strong technological orientation actively monitor technological advancements, invest in research and development, and utilize technology to gain a competitive edge42. Technical orientation boosts a firm’s ability to innovate and adjust to shifting market demands. Companies focused on technology are more likely to adopt digital transformation and sustainable practices40. Research conducted by Masa’deh et al.42 demonstrates that a technological orientation has a positive impact on firm performance, especially in dynamic and competitive environments. A technological orientation is a key driver of innovation, agility, and sustained success in today’s enterprises.

Organizational green innovation

Organizational green innovation involves developing and implementing new products, processes, or practices within an organization that aim to reduce environmental impact and promote sustainability34. It encompasses advancements like environmentally sustainable product design, energy-efficient technologies, waste reduction strategies, and sustainable supply chain practices. Green innovation seeks to align environmental performance with economic objectives by integrating environmental considerations into core business strategies43. Chen et al.89 assert that green innovation enhances a firm’s competitive advantage by improving its reputation, ensuring regulatory compliance, and boosting operational efficiency44. Organizations that pursue green innovation often foster a culture of environmental stewardship and continuous improvement45. Research has confirmed that green innovation positively impacts both environmental and financial performance46. It also promotes long-term sustainability by conserving resources and engaging stakeholders. Organizational green innovation plays a vital role in advancing eco-efficiency and sustainable development within today’s environmentally conscious corporate landscape.

Hypotheses development

Ecocentric leadership and organization green innovation

Ecocentric leadership represents a value-driven leadership style that places sustainability and environmental stewardship on par with traditional business objectives17. It seeks to promote synergy between human activity and the natural environment, signifying a notable paradigm shift in management towards a more holistic and environmentally conscious approach15. Prior studies indicate that ecocentric leadership fosters innovation within organizational contexts16. Biswas et al.26 provided evidence supporting the impact of ecocentric leadership on green innovation by promoting the development of crucial competencies and capabilities through collaborative decision-making processes directed towards collective objectives. Eco-centric leaders are dedicated to ongoing learning and employ a shared vision to raise understanding and appreciation of the organization’s purpose and goals among its employees23. They spearhead innovation efforts within the organization and contribute to the market success of novel products and services through inspiring motivation and intellectual stimulation47.

Previous studies indicate that eco-centric leaders prioritizing environmental sustainability tend to shape how employees perceive their roles and engage with environmental issues31. This steadfast commitment often inspires employees to reciprocate through proactive participation in green innovation initiatives11. Ecocentric leadership promotes organizational green innovation by strongly emphasizing environmental sustainability as a core value8. This focus has the potential to inspire and enable employees to voluntarily adopt environmentally friendly practices, thereby contributing to the organization’s overall green initiatives48. Research has highlighted the ability of eco-centric leaders to articulate a clear environmental vision and cultivate a supportive, environmentally conscious culture within their organizations. This culture can catalyze driving organizational green innovation49. In alignment with social exchange theory, when employees witness their leaders’ dedication to environmental sustainability, they are motivated by a moral obligation to participate in the organization’s green initiatives50. Based on the above arguments, it can be hypothesized that:

Hypothesis 1

Ecocentric leadership will positively influence the organization’s green innovation.

Ecocentric leadership predicts organizational green innovation: the mediating role of employee green knowledge sharing

Ecocentric leadership, which prioritizes environmental sustainability and responsibility, has garnered increasing attention in organizational research because of its potential to drive green innovation within organizations26. This concept suggests that leaders who prioritize ecological values are more likely to inspire and motivate their employees to engage in environmentally responsible behaviors and initiatives15.

One critical pathway through which ecocentric leadership influences organizational green innovation is fostering employee green knowledge sharing51. Green knowledge sharing encompasses disseminating environmentally relevant information, ideas, and practices among employees32,33. When leaders prioritize environmental sustainability and demonstrate their commitment to green initiatives, they cultivate an environment that inspires and motivates employees to share knowledge and ideas about sustainability efforts8,52. Eco-centric leaders typically exhibit behaviors such as setting clear environmental goals, providing resources for eco-friendly initiatives, and actively participating in sustainability practices53,54. Employees are more inclined to participate in knowledge sharing when they perceive that their contributions are valued and align with the organization’s overarching goals and values55. These actions tell employees that the organization prioritizes environmental sustainability, increasing their motivation to participate in green innovation efforts51,56.

Furthermore, in line with social exchange theory, ecocentric leadership fosters collaboration and openness, where employees feel empowered to exchange ideas and information related to sustainability initiatives57,58. This collaborative culture facilitates knowledge sharing and enhances creativity and innovation within the organization59. Studies have found that organizations with leaders who firmly commit to environmental sustainability tend to exhibit higher levels of employee engagement in green knowledge-sharing activities11. Additionally, these organizations are more likely to develop and implement innovative green initiatives, contributing to their overall environmental performance and competitive advantage11.

We contend that ecocentric leadership is pivotal in advancing organizational green innovation. This is achieved by cultivating a culture of sustainability, motivating employees to participate in sharing green knowledge, and ultimately facilitating the development and implementation of innovative environmental practices. By recognizing the significance of ecocentric leadership and investing in initiatives that promote environmental responsibility, organizations can position themselves as leaders in sustainable business practices. This, in turn, allows them to contribute to a more environmentally sustainable future60,61.

Hypothesis 2

The relationship between ecocentric leadership and organizational green innovation will be mediated by green knowledge-sharing.

Green ambidexterity mediates the relationship between ecocentric leadership and organizational green innovation.

Green ambidexterity describes an organization’s capacity to both explore new environmentally sustainable opportunities green exploration) and exploit existing green initiatives and capabilities green exploitation)36,37. It involves balancing innovation and efficiency in pursuing environmental sustainability goals38,62. Ecocentric leadership is instrumental in cultivating green ambidexterity by fostering an organizational climate that encourages the simultaneous exploration and exploitation of green opportunities63. Eco-centric leaders promote green ambidexterity by encouraging a culture of experimentation and risk-taking to pursue innovative green solutions green exploration64. They empower employees with resources, support, and autonomy to innovate new ideas and technologies that promote environmental sustainability65,66. Simultaneously, eco-centric leaders ensure that the organization effectively leverages its existing green initiatives and capabilities by optimizing processes, improving efficiencies, and scaling successful sustainability practices36.

Furthermore, ecocentric leaders guide organizations in adapting to evolving environmental regulations, market trends, and stakeholder expectations by concurrently exploring new avenues for sustainability and leveraging existing green capabilities67. Organizations can drive continuous green innovation by balancing exploration and exploitation by effectively managing the trade-offs between immediate benefits and long-term sustainability goals68. Ecocentric leaders foster a climate of openness to new ideas, collaboration across functional areas, and continuous learning and improvement. Additionally, eco-centric leaders align organizational goals and incentives with environmental sustainability objectives to prioritize and reward green innovation69,70.

We argue that green ambidexterity serves as an underlying mechanism linking ecocentric leadership to organizational green innovation. Organizations can effectively drive innovation in environmentally sustainable practices by exploring new green opportunities and exploiting existing capabilities71,72.

Hypothesis 3

The path between ecocentric leadership and organizational green innovation will be mediated by green ambidexterity.

Serial mediation

Expanding upon prior literature and theories, this study proposes that green knowledge sharing and green ambidexterity play a chain-mediating role in translating ecocentric leadership into organizational green innovation. Ecocentric leaders set an example by prioritizing environmental concerns and integrating green practices into their organizational culture14,73. This communicates to employees that sustainability is highly regarded, motivating them to participate in environmentally responsible behavior. In return, employees may feel obligated to reciprocate this positive behavior by sharing their knowledge and ideas related to green initiatives26,74. This sharing of knowledge facilitates the development of green ambidexterity within organizations. In addition, ecocentric leaders play a crucial role in promoting this ambidextrous mindset by encouraging employees to continuously improve existing green initiatives while exploring and experimenting with new environmentally sustainable solutions33,53. Organizations can better leverage ecocentric leadership to drive sustainable innovation and competitive advantage by understanding the mediating roles of green knowledge sharing and green ambidexterity.

Hypothesis 4

Green knowledge sharing and green ambidexterity sequentially mediate the relationship between ecocentric leadership and organizational green innovation.

Moderation and the moderation mediation effect of technological orientation

We argue that ecocentric leadership, characterized by a commitment to environmental sustainability and responsibility, and a technological orientation that emphasizes the strategic use of technology for organizational advancement, can synergistically enhance green knowledge sharing. Technological orientation complements ecocentric leadership by providing the tools and platforms necessary for efficient and effective knowledge-sharing21,75. Technology facilitates the communication, collaboration, and dissemination of information across organizational boundaries. Through technological platforms, such as intranet portals, social media, and knowledge management systems, employees can easily access and share green knowledge, best practices, and innovative ideas related to sustainability initiatives11,76. Ecocentric leaders leverage technology to reinforce green messaging, communicate sustainability goals, and recognize and reward environmentally responsible behaviors22. Meanwhile, technological tools enable leaders to collect data on environmental performance, track progress toward sustainability targets, and disseminate this information transparently to employees, fostering accountability and engagement7,77.

Moreover, technological platforms provide avenues for interactive learning and collaboration78, enabling employees to contribute their insights, experiences, and suggestions for improving environmental practices79,80. This democratization of knowledge sharing empowers employees at all levels to participate actively in the organization’s sustainability efforts, fostering a sense of ownership and collective responsibility toward environmental stewardship81. Organizations can create a dynamic ecosystem where ideas can flourish and translate into tangible environmental benefits by linking ecocentric leadership and technology-enabled knowledge sharing to green innovation. This approach drives continuous improvement in sustainability practices and positions the organization as a leader in green innovation, fostering competitiveness and long-term success in an increasingly environmentally conscious marketplace82,83.

Furthermore, social exchange theory explains how ecocentric leadership drives green knowledge sharing by emphasising mutual benefits and reciprocity24. Leaders prioritising sustainability foster a culture where employees share green knowledge, anticipating positive outcomes15. Technological orientation enhances this by increasing the perceived value of knowledge sharing through advanced tools, making exchanges more efficient and rewarding81. This strengthens the leader–follower relationship and promotes green innovation. Research highlights that in tech-savvy environments, the benefits of sharing green knowledge are amplified, fostering greater engagement and sustainable innovation4. Based on support from literature and theory, we propose the following hypothesis.

Hypothesis 5

Technological orientation moderates the path of ecocentric leadership with green knowledge-sharing behavior, such that this relationship is strong when technological orientation is high.

Hypothesis 6

The indirect mediated path between ecocentric leadership and organization green innovation through green knowledge sharing is moderated by technological orientation, such that this indirect effect is strong with high levels of technological orientation.

Research method

Participants and procedure

The participants in this study were hotel employees from Guangdong Province, China. Guangdong is a highly developed metropolitan area with a robust hospitality sector. The data collection method used in this study was convenience sampling. This approach was selected due to the fast-paced nature of the hospitality industry, characterised by constant customer interactions, dynamic environments, and sufficient staff availability to gather data on the study variables: Ecocentric Leadership, Technological Orientation, Green Knowledge Sharing, Green Ambidexterity, and Organisational Green Innovation. Convenience sampling enables researchers to collect data efficiently without the need for complex sampling frameworks, making it particularly suitable for industries where time and resource constraints are significant. Moreover, while random sampling methods are rigorous, they can be costly and time-consuming. Convenience sampling mitigates these expenses by focusing on readily available participants, making it a practical and attractive option for hospitality businesses with limited budgets. Additionally, implementing structured sampling methods can be logistically challenging in high-traffic and transient environments due to the industry’s high volume of staff engagement. Convenience sampling addresses this challenge by allowing researchers to collect insights from employees who are easily accessible and directly involved in daily operations. To ensure ethical standards, supplementary letters were provided to guarantee the confidentiality and privacy of respondents’ data. Informed consent was obtained from all participants before their involvement in the study. The research initially targeted 250 hotels in Shenzhen City, focusing on establishments with ratings between 2 and 5 stars. The primary respondents were mid-level employees, often directly involved in implementing green practices and innovation within their organisations. Data collection was conducted in two phases Time-lagged approach) to address common method bias84. Initially, 960 questionnaires were distributed to hospitality organizations, covering demographics, ecocentric leadership, and technological orientation, yielding 773 responses 80.52% response rate). Subsequently, these respondents were re-engaged in collecting data on green knowledge sharing, green ambidexterity, organizational green innovation, and social desirability, resulting in 667 surveys being returned, with 623 deemed valid 64.89% response rate). Seventy-three percent of the respondents had bachelor’s degrees, and the majority 68%) claimed having one to five years of experience.

Discussion and conclusion

The findings of this study affirm both the direct and indirect impacts of ecocentric leadership on organizational green innovation. The study also supports the sequential mediation path, encompassing ecocentric leadership to organizational green innovation via green knowledge sharing and green ambidexterity. Moreover, moderation effects were observed, where technological orientation moderated the direct effect between ecocentric leadership and green knowledge sharing and indirectly moderated the path between ecocentric leadership and organizational green innovation via green knowledge sharing.

Our first hypothesis asserts that ecocentric leadership is vital in organizational green innovation. Ecocentric leadership emphasizes a deep commitment to environmental sustainability and integrating ecological principles into leadership practices26. Research indicates that leaders embracing an eco-centric approach firmly commit to environmental sustainability. They prioritize ecological considerations in their decision-making processes and encourage organizations to adopt green practices and innovations17. Eco-centric leaders are acutely aware of the importance of environmental preservation. They understand the potential long-term consequences of unsustainable practices and prioritize protecting natural resources16. Leaders who uphold eco-centric values and prioritize environmental responsibility are instrumental in fostering a culture of sustainability within their organizations. By championing these values, they create an environment where employees are empowered to engage in green initiatives and innovate for sustainability. Ecocentric leadership involves strategically integrating sustainability goals into organizational strategies and operations. Eco-centric leaders who adopt a strategic approach to sustainability are better positioned to drive green innovation by aligning environmental objectives with business objectives, allocating resources to green initiatives, and promoting collaboration across departments e.g.,15,47.

The second underpinning of our research is regarding the underlying mechanism of “green knowledge sharing” between ecocentric leadership and organizational green innovation. Our findings indicate that eco-centric leaders prioritize environmental sustainability and encourage knowledge-sharing related to green practices and innovations. Eco-centric leaders create a supportive environment where employees feel empowered to exchange ideas, best practices, and lessons learned regarding environmental sustainability, thus fostering green knowledge sharing within the organization e.g.,53,56. Eco-centric leaders who promote knowledge sharing contribute to disseminating environmental values, awareness, and expertise throughout the organization, enhancing the organization’s capacity for green innovation82. Previous studies have highlighted the importance of knowledge sharing in facilitating innovation. Sharing information, expertise, and experiences related to environmental processes and market trends enables organizations to identify opportunities, overcome challenges, and develop novel solutions for sustainability e.g., Chen et al., 2018). Therefore, organizations with a culture of green knowledge-sharing are more likely to generate innovative ideas and implement environmentally friendly practices.

Our third research inquiry investigated the mediating role of green ambidexterity in the relationship between ecocentric leadership and organizational green innovation. The study results assert that eco-centric leaders will likely foster a strategic orientation toward environmental sustainability within their organizations37,63. They emphasize the importance of integrating ecological principles into an organization’s vision, mission, and strategic goals. This strategic orientation provides a foundation for pursuing green ambidexterity by encouraging the exploration of new green opportunities and exploiting existing green capabilities71. Previous research has highlighted the positive impact of green ambidexterity on organizational innovation performance65. Organizations that adopt a balanced approach of exploring new environmentally sustainable practices while leveraging existing green resources and capabilities are well-positioned to develop innovative solutions to address environmental challenges and effectively meet stakeholder expectations. Green ambidexterity enables organizations to adapt to changing environmental conditions, anticipate market trends, and create value through green innovation67. Eco-centric leaders who promote a culture of green ambidexterity encourage employees to balance experimentation with efficiency, risk-taking with stability, and short-term gains with long-term environmental benefits. This balanced approach to innovation enables organizations to effectively translate eco-centric principles into tangible green innovation outcomes37.

The fourth study question concerns the moderating role of technological orientation. Our results show that organizations with high technological orientation prioritize adopting and utilizing technology to drive green innovation. Previous studies indicate that technological orientation encompasses an organization’s readiness to invest in technology, its emphasis on technological development, and its capacity to leverage technology for strategic purposes78. Such organizations are more likely to embrace digital platforms, collaborative tools, and knowledge management systems to facilitate knowledge sharing and innovation21. Eco-centric leaders recognize the importance of leveraging technology to support environmental sustainability initiatives and advocate the adoption of green technologies, digital platforms, and information systems to enhance the organization’s environmental performance and facilitate green innovation27. They promote a culture of technological readiness, encouraging employees to use digital tools and platforms to share environmental knowledge and best practices. Technological orientation moderates the relationship between ecocentric leadership and green knowledge-sharing behavior by shaping the organizational context in which knowledge-sharing occurs5. In organizations with a high technological orientation, the infrastructure and resources necessary for knowledge-sharing are readily available, making it easier for eco-centric leaders to promote and facilitate green knowledge-sharing initiatives81. Digital platforms, collaboration tools, and information systems enable employees to share real-time environmental insights, expertise, and innovations, fostering a culture of continuous learning and environmental improvement77.

In light of the literature and SET, our findings indicate that ecocentric leadership is crucial for promoting organisational green innovation within the hospitality sector. This study conducted a thorough investigation, uncovering a serial mediation pathway that includes green knowledge sharing and green ambidexterity. It clarifies how ecocentric leadership affects proactive cognition and facilitates the spread of green knowledge, ultimately propelling green innovation. Additionally, the study identifies technological orientation as a moderating factor, suggesting that the connection between ecocentric leadership and organisational green innovation through green knowledge sharing is reinforced when technological orientation is elevated. In the hospitality sector, where sustainability and environmental impact are becoming increasingly significant, such leadership can greatly enhance green practices and innovations, resulting in more sustainable operations and improved environmental performance.

Theoretical implications

Guided by social exchange theory, this study adds many theoretical contributions by integrating ecocentric leadership, green knowledge sharing, green ambidexterity, and technological orientation. This integration sheds light on the mechanisms that drive organizational green innovation. First, it contributes to the burgeoning literature on ecocentric leadership by demonstrating its positive influence on organization-level outcomes, specifically green innovation, within the hospitality sector. By emphasizing values such as environmental stewardship, social responsibility, and long-term sustainability, ecocentric leaders in the hospitality industry create a climate conducive to innovation that aligns with their ecological goals26. This extends prior research on leadership theories, which predominantly focus on traditional performance outcomes, by highlighting the importance of sustainability-oriented leadership in driving environmentally responsible practices within the hospitality sector92.

Second, investigating green knowledge sharing as a mediator adds nuance to our understanding of how ecocentric leadership affects organizational outcomes in the hospitality sector. Green knowledge sharing reflects employees’ dissemination and integration of environmentally relevant information, ideas, and practices. By fostering a culture of openness, collaboration, and learning, ecocentric leaders in the hospitality industry facilitate the exchange of knowledge essential for identifying and implementing green initiatives15. This underscores the importance of social exchange processes in promoting sustainability-oriented behavior within organizations. Furthermore, this study extends theoretical insights into green ambidexterity while discussing new opportunities for green innovation. By integrating exploitation and exploration processes within the context of sustainability, this study highlights the dynamic nature of organizational adaptation to environmental challenges65. Ecocentric leadership plays a critical role in promoting both exploitation efficient use of existing resources for sustainability) and exploration seeking new green opportunities)93, thereby enabling organizations to achieve green ambidexterity and maintain competitiveness in environmentally conscious markets.

Third, this study uncovers the sequential chain of causal processes linking ecocentric leadership to organizational green innovation by investigating serial mediation. Specifically, eco-centric leaders foster an environment conducive to employee knowledge sharing, promoting green ambidexterity within the organization16. This serial mediation framework provides a deeper understanding of the interrelated pathways through which leadership behaviors shape organizational responses to environmental challenges. This highlights the importance of considering direct and indirect effects operating through intermediate processes in the pursuit of sustainability goals. Moreover, incorporating serial mediation into the theoretical framework enriches our understanding of the causal mechanisms underlying the influence of ecocentric leadership on organizational green innovation. By delineating the sequential pathways through which leadership behaviors propagate throughout the organization to drive sustainability-oriented outcomes, this study offers valuable insights for theoretical development and practical implementation in environmental management and sustainable business practices.

Fourth, examining technological orientation as a moderator enriches our understanding of the boundary conditions regarding how ecocentric leadership affects organizational green innovation through green knowledge sharing21. Technological orientation reflects the extent to which an organization prioritizes adopting and utilizing technology to support its environmental objectives81. The findings suggest that organizations with a high technological orientation may leverage digital platforms, tools, and systems to enhance the effectiveness of green knowledge-sharing initiatives initiated by ecocentric leaders. This underscores the interactive effects of leadership behaviors and organizational context in shaping sustainability outcomes. Finally, in contrast to previous research that qualitatively examines the impact of leadership on organizational green innovation, the current study quantitatively investigates how organization green innovation is influenced by eco-centric leadership, considering factors such as green knowledge sharing, green ambidexterity, and technological orientation. This research facilitates an objective analysis of causal effects by employing statistical methods, such as structural equation modeling (SEM) using Mplus, which provides empirical evidence to underpin the hypothesized link between ecocentric leadership, green knowledge sharing, green ambidexterity, technological orientation, and organizational green innovation. Using SEM through Mplus enhances the extrapolative strength of the results. It overcomes the limitations of qualitative approaches that rely on individual perceptions. This guarantees validation based on data and improves the broader applicability of the findings.

Practical implications

Companies are actively aligning their environmental commitments with their leadership roles in the swiftly changing business environment. They are moving towards sustainable, eco-friendly strategies and practices, especially in response to the increasingly strict environmental regulations. Proactive and self-motivated green initiatives undertaken by employees are essential in driving an organisation’s sustainable innovation. Thus, this study identifies the primary factors that can inspire and nurture green innovation within organisations. The aim is to ensure that organisations comply with regulatory requirements and leverage the innate motivation of their employees to promote environmental advancements.

Organisations can implement leadership development programmes that emphasise ecocentric leadership competencies. Training sessions, workshops, and coaching programmes can be designed to cultivate leadership behaviours that prioritise environmental stewardship, social responsibility, and long-term sustainability. Organisations can foster a culture that supports green knowledge-sharing and innovation by equipping leaders with the necessary skills and mindset.

Recognising the pivotal role of green knowledge sharing in facilitating green innovation, organisations can implement initiatives to promote information exchange and collaboration among employees. This may involve creating online platforms, forums, or communities of practice dedicated to sharing best practices, success stories, and lessons learned from environmental sustainability initiatives. Encouraging cross-functional teams and interdepartmental collaboration can also enhance the dissemination of green knowledge across organisations.

Organisations can promote green ambidexterity by balancing the exploitation of existing green practices with the exploration of new, environmentally sustainable opportunities. Managers can encourage experimentation, risk-taking, and innovation in green initiatives while simultaneously optimising the efficiency and effectiveness of current sustainability practices. By fostering a culture that values both continuity and change in environmental management, organisations can adapt to evolving sustainability challenges and seize emerging opportunities.

Furthermore, considering the moderating effect of technological orientation, organisations can utilise technology to enhance ecocentric leadership initiatives and bolster green knowledge-sharing efforts. Investing in digital platforms, collaborative tools, and data analytics systems can facilitate communication, cooperation, and knowledge exchange among employees, particularly in geographically dispersed and remote work environments. By leveraging the potential of technology, organisations can overcome barriers to green innovation and accelerate the implementation of sustainable practices.

Limitations and future research directions

Our research has limitations that present opportunities for future scholars to bridge the gap and enhance the literature. Firstly, a cross-sectional approach was employed to gather the data, making it more challenging to establish a causal relationship between the variables. Future research may employ experimental or longitudinal approaches to gain a deeper understanding of how ecocentric leadership, green information sharing, green ambidexterity, and organizational green innovation interact dynamically over time. Measuring constructs such as ecocentric leadership, green knowledge sharing, and green ambidexterity may be subject to standard methods or self-report biases. Future studies could employ multi-source, multi-method approaches to enhance the validity and reliability of these findings. Second, this study has focused on a specific industry, namely the hospitality sector. Additionally, geographical regions, such as China, may potentially limit the applicability of the findings. Future research could conduct similar investigations in diverse contexts to assess the broader relevance of the relationships across different organizational settings. Third, this study primarily examined the short-term outcomes associated with organizational green innovation. Future research could evaluate the enduring impacts of ecocentric leadership, green knowledge sharing, and green ambidexterity on organizational sustainability performance, competitive advantage, and financial outcomes. Finally, while this study focused on serial mediation and the moderating role of technological orientation, other mediating and moderating variables may also influence the relationships among ecocentric leadership, green knowledge sharing, green ambidexterity, and organizational green innovation. Future investigations may need to explore additional mechanisms, such as organisational culture, top management support, the role of artificial intelligence, environmental factors, and available resources, to provide a deeper understanding of the related processes.
