Fig. 2: A theoretical model of the green development behavior of construction enterprises.

It shows 7 groups of hypothetical relationships of green development behavior of construction enterprises. Among them, H1–H3 explores the direct relationship between attitude, subjective norms, and perceived behavioral control and intention, respectively, and the intermediating effect of intention (H5) in the three groups of relationship: attitude–behavior (H5a), subjective norms–behavior (H5b) and perceived behavior control–behavior (H5c). H4 explores the direct effect of perceived behavior control and behavior. And the moderating effect of regional green development level (H6a, H6b, H6c, H6d, H6e) and enterprise-size (H7a, H7b, H7c, H7d, H7e) on the above relationship.
