Collaborative Analysis of Ecological Profit and Loss and Economic Efficiency in the Yangtze River Delta Region
The article uses an adjusted ecological profit and loss model to calculate the per capita ecological profit and loss index of 41 prefecture level cities in the Yangtze River Delta region from 2010 to 2019.The ESDA method is used to analyze the spatiotemporal distribution characteristics,and the Super-SBM model is used to measure the economic efficiency values of 41 cities in different years.Based on efficiency analysis,an ecological economic structure deviation index is constructed to measure the synergistic relationship between ecological environment and economic efficiency.The results show that:(1)the per capita ecological profit and loss index in the Yangtze River Delta region is on a downward trend,and there is a certain spatial agglomeration effect;(2)The production decision adjustments made to improve urban economic efficiency are highly likely to be inconsistent with the development of the local ecological environment;(3)Resource allocation and agglomeration based on urban economic efficiency will to some extent exacerbate the two-level differentiation of regional ecological environment.
