长三角地区生态盈亏及经济效率协同分析

Collaborative Analysis of Ecological Profit and Loss and Economic Efficiency in the Yangtze River Delta Region

文章运用调整后的生态盈亏模型,对2010—2019年长三角地区41个地级市人均生态盈亏指数进行测算,采用ESDA方法分析其时空分布变化特点,同时运用Super-SBM模型对41个城市不同年份经济效率值进行测度,基于效率分析并构建生态-经济结构偏差指数对生态环境与经济效率之间的协同关系进行衡量。结果表明:(1)长三角地区人均生态盈亏指数处于下降趋势,且存在一定的空间集聚效应;(2)为了提高城市经济效率而做出的生产决策调整,极有可能与当地生态环境的开发情况不相协同;(3)以城市经济效率为考量进行的资源分配与集聚,一定程度上将加剧地区生态环境的两极分化。

The article uses an adjusted ecological profit and loss model to calculate the per capita ecological profit and loss index of 41 prefecture level eities in the Yangtze River Delta region from 2010 to 2019.The ESDA method is used to analyze the spatiotermporal 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.
