中国三大城市群生态福利绩效测算与比较

Calculation and Comparison of Ecological Welfare Performance in China’s Three Major Urban Agglomerations

文章基于2009—2018年京津冀、长三角和珠三角城市群48个城市的面板数据,利用两阶段SuperNSBM模型、MLD指数模型和PECM模型对生态福利绩效进行测算与比较。结果表明:三大城市群总体生态福利绩效水平偏低,生产发展阶段生态福利绩效水平低于服务发展阶段,MLD指数呈“N”型变化且变动差距缩小;京津冀城市群对生态福利绩效差距缩小的贡献率最大,但产业结构优化效果不显著;长三角城市群中等生态福利绩效水平居多,产业结构优化能够显著促进生态福利绩效水平的提高;珠三角城市群生态福利绩效水平差距最明显,技术进步抑制了生态福利绩效水平的提高。

Based on the panel data of 48 cities in Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta urban agglomerations from 2009 to 2018, this paper uses the two-stage Super-NSBM model, MLD index model and PECM model to measure and compare the ecological welfare performance(EWP). The results go as the following: The overall EWP level of the three major urban agglomerations is low;EWP of the production development stage is lower than that of the service development stage;the MLD index shows an“N”-shaped change with a narrowing gap.The contribution of Beijing-Tianjin-Hebei urban agglomeration to the narrowing of EWP gap is the greatest, but the effect of industrial structure optimization is not significant.The Yangtze River Delta urban agglomerations are mostly at the medium level of EWP, and the optimization of industrial structure can significantly promote the improvement of EWP.The difference of EWP in the Pearl River Delta urban agglomeration is the most obvious, and the progress of science and technology inhibits the improvement of EWP.
