COORDINATED DEVELOPMENT AND SPATIAL RELATIONSHIP ANALYSIS OF ENERGY-ECONOMY-ENVIRONMENT IN THE YANGTZE RIVER ECONOMIC BELT, CHINA

With the continuous development of society and economy, the current problems of energy shortage and environmental degradation have appeared in many countries around the world. In order to analyze the complex relationship of the three elements in the energy-economic-environment (3E) system. Based on a multivariate coupling model and a spatial perspective, this paper analyzes the degree of coupling and coordination of energy, economic, and environmental systems in 11 provinces and cities in the Yangtze River Economic Belt from 2008 to 2017, and uses a spatial econometric model to study spatial correlation of the 3E system in the Yangtze River Economic Belt. The measurement of coupling coordination degree shows that the energy, economy and environment factors of the provinces and cities in the Yangtze River Economic Belt are in the moderate coupling coordination stage as a whole. There is still a large gap from the high level of coordination. The global spatial correlation analysis results show that there is a significant spatial correlation in the coordination level of the 3E system elements in each region of the Yangtze River Economic Belt. The measurement results of local spatial correlation show that Shanghai and Zhejiang have obvious spatial agglomeration effects with high coupling and coordination in the Yangtze River Economic Belt.
