Research on the Coupling Coordination Development of Industry-University-Research, Regional Economy and Ecological Environment and Their Spatial Spillover Effects

Abstract

This paper applies the coupling model to study the coupling coordination development of industry-university-research, ecological environment and regional economy in 30 provinces and cities in China from 2009 to 2019, on the basis of which, this paper further applies the spatial Durbin model to measure the spatial spillover effects of the three subsystems. The results show that: (1) During the study period, China's IUR-Economy-Ecology system is characterized by high coupling degree and low coupling coordination degree, in which 83% of China's regions are lagging in industry-university-research, and the regional distribution shows a diamond-shaped distribution of "high in the east, flat in the northeast and the middle, and low in the West ". (2) The IUR-Economy-Ecology, economic and ecological system has obvious spatial polarization effect. (3) The industry-university-research system has spatial diffusion effect, which indicates that promoting industry-university-research cooperation is conducive to the promotion of the balanced regional development. (4) The industry-university-research innovation system, relative to the economic and ecological systems, has a "wooden barrel effect" in the process of promoting the coupled and coordinated development of IUR-Economy- Ecology system, and promoting the development of industry-university-research innovation system can most efficiently improve the "capacity ceiling" of the total system.
