Research on the Coupling and Coordination Degree of Economic Development and Ecological Environment—Based on Panel Data Analysis of Thirteen Cities in Jiangsu Province
Green and low-carbon economic development is a key link in achieving high-quality development.Therefore,taking the economic development and ecological environment of Jiangsu Province as the research object,the entropy weight method and coupling coordination model were used to construct the coupling evaluation index system of ecological environment and economic development in Jiangsu Province.The spatial distribution characteristics of the coupling coordination degree of ecological environment and economic development in thirteen cities in Jiangsu Province were analyzed.The coupling coordination model was evaluated using a neural network model,and the temporal variation characteristics of the coupling coordination degree were analyzed.The grey prediction model was used to predict the coordination degree of ecological environment and economic development in Jiangsu Province.The research results show that the coupling coordination degree between economic development and ecological environment in Jiangsu Province has significant spatiotemporal distribution differences;from a spatial perspective,cities such as Suzhou,Nanjing,and Wuxi have a higher level of coupling and coordination,while cities such as Lianyungang,Zhenjiang,and Suqian have a lower level of coupling and coordination;from the perspective of time distribution,the overall coupling and coordination level of the economy and environment in Jiangsu Province has shown a trend of increasing year by year.Based on this,strategies and suggestions are provided to promote the coordinated development of economy and environment in Jiangsu Province.
