Table 1 Description of positive loop (R), negative loop (B) and exogenous causal linkage (E).
From: Modelling and evaluating wood supply chain resilience factors based on system dynamics
Feedback Linkage | Description |
|---|---|
R1 | GDP growth increases wood imports, boosting wood processing and manufacturing, which in turn stimulates further GDP growth |
R2 | Improvements in transportation and storage infrastructure, enhancing wood supply and manufacturing, which further boosts GDP |
R3 | The development of logistics networks and talent improve wood supply and manufacturing, leading to further GDP growth |
R4 | GDP enhances logistics efficiency, improving product transportation and sales coordination, which further stimulates GDP growth |
R5 | GDP growth increases R&D investment, driving industry expansion and boosting manufacturing output, reinforcing GDP growth |
R6 | Improvements in power stability, automation, and clean energy use enhance manufacturing efficiency, contributing to GDP growth |
R7 | GDP growth leads to more furniture companies, boosting sales and improving production-sales coordination, which feeds back into GDP growth |
R8 | GDP growth increases consumer spending, improving production-sales coordination and further stimulating GDP growth |
B1 | Barriers to wood imports, such as customs delays, disrupt the supply chain and reduce production capacity, negatively affecting manufacturing and economic growth |
B2 | Misalignment between production and sales reduces economic efficiency and hampers GDP growth |
E1 | External factors like port services directly affect wood import supply, but do not receive feedback from the system |
E2 | Tariffs and external policies affect wood imports |
E3 | Issues like unhealthy competition, product homogeneity, and waste hinder production efficiency |
E4 | Sales logistics risks and market changes affect furniture sales |
E5 | Changes in the target consumer group affect sales |
