Outline
The proximity between the subjects of construction projects is an important factor that affects the performance of cooperative innovation. Based on the theory of multidimensional proximity, the longitudinal data of the cooperative innovation among Chinese project participants was collected to explore the influence mechanism of geographical, organizational, technological, institutional and relationship proximity on the cooperative innovation performance of construction enterprises. In order to better reveal the statistical and aggregate relationship between variables, negative binomial regression and fuzzy set qualitative comparative analysis(fsQCA) were used to analyze the binary relationship of cooperative innovation of 392 construction enterprises. The results show that geographical proximity, organizational proximity, institutional proximity, technological proximity and relationship proximity all significantly promote the cooperative innovation performance of construction enterprises. The antecedent configuration of high cooperative innovation performance of three types of construction enterprises is obtained by qualitative comparison and analysis, namely, “organizational leadership-resource integration” type, “system traction-cross-domain breakthrough” type and “technology coordination-collaborative creation” type.
