中国生态福利绩效测度与空间敛散性分析

Measurement of Ecological Welfare Performance and Analysis of Spatial Convergence and Divergence in China

文章使用super-SBM模型,对中国30个省与东、中、西地区2010—2019年的生态福利绩效进行测度。在此基础上,运用空间计量模型研究各区域及全国整体生态福利绩效的空间敛散性。结果表明:中国生态福利绩效整体处于较高水平,区域间存在显著差异性,且东、中、西部生态福利绩效水平呈依次递减。东部地区生态福利绩效空间敛散性变化态势为分散—收敛—分散;中部地区生态福利绩效先趋于分散,后进入持续变化状态;西部地区呈先分散后收敛趋势。另外,对外开放度、绿化覆盖率、城镇化水平等因素对中国生态福利绩效敛散性存在异质性影响。

This paper uses the super-SBM model to measure the ecological welfare performance of 30 provinces and eastern,cen-tral and western regions in China from 2010 to 2019.On this basis,the spatial econometric model is used to study the spatial conver-gence and divergence of regional and national overall ecological welfare performance.The results show that the overall ecological welfare performance in China is at a high level,and there are significant regional differences.The spatial convergence and divergence of the ecological welfare performance in the eastern region shows a trend of dispersion-convergence-divergence.The performance of ecological welfare in central region tends to be decentralized first,and then enters a state of continuous change.The western region shows a trend of first dispersion and then convergence.In addition,openness,urbanization level and innovation efficiency and other factors have heteroge-neous effects on the convergence and dispersion of China's ecological welfare performance.
