长三角地区经济增长质量与生态环境优化的耦合协调度分析

Analysis of Coupling Coordination Degree between Economic Growth Quality and Environmental Optimization in Yangtze River Delta Region

利用耦合协调度分析了长三角27个核心城市经济增长质量与生态环境优化的联系。通过总结经济学中经济增长质量的相关研究,比较多种测度方法,选取DEA-Malmquist指数代表经济增长质量指数;生态环境优化方面使用熵值法,选取6个相关指标测度生态环境优化指数。对两指数进行计算,得到二者的耦合协调度。分析可知,长三角27个核心城市中,大多数城市的耦合协调度很高,但少数城市耦合协调度较低,且在下降。对此给出了相关建议。

In this paper, the coupling coordination degree is used to analyze the relationship between the quality of economic growth and the optimization of ecological environment of 27 core cities in the Yangtze River Delta. By summarizing the relevant research on the quality of economic growth in economics and comparing a variety of measurement methods, the DEA-Malmquist index is selected to represent the quality of economic growth, and the entropy method is used to measure the ecological environment optimization index. Six related indicators were selected to measure the ecological environment optimization index. By calculating the two indexes, the degree of coupling coordination of the two indexes is obtained. The results show that most of the 27 core cities in the Yangtze River Delta have a high degree of coupling coordination, but a few cities have a low degree of coordination and are declining. This paper gives some suggestions.
