资源配置视角下长三角城市群生态福利绩效评价及其空间溢出效应OA北大核心CHSSCDCSTPCD
Evaluation of ecological welfare performance and spatial spillover effects in the Yangtze River Delta urban agglomeration from a resource allocation perspective
长三角城市群是我国经济发展的重要引擎,探究该区域的生态福利绩效对我国的高质量发展具有重要的现实意义.为此,从资源配置视角和多维评价指标体系出发,改进了生态福利绩效的两阶段链式转化结构模型,并据此构建了考虑非期望中间产出弱可处置性的两阶段链式超效率DEA模型,测度长三角城市群2011-2021年的全局生态福利绩效及分阶段效率,并利用双固定效应下的空间杜宾模型揭示长三角城市群生态福利绩效空间溢出效应,探究长三角城市群生态福利绩效的提升路径.研究结果表明:(1)长三角城市群全局生态福利绩效的平均水平维持在0.8左右,但有68.3%的城市处于非有效状态,且城市之间存在较为显著的差距.(2)分阶段来看,生态-经济效率为0.685,经济-福利效率为0.863,差异主要来自三省一市内部,组内贡献率分别为77.39%与77.14%,发展较不均衡.(3)长三角城市群生态福利绩效具有较强的空间正相关性,而建成区绿化覆盖率、生活垃圾无害化处理率、人均GDP、城市人均每年消费额、政府干预对长三角城市群生态福利绩效提高具有正向促进效应,且建成区绿化覆盖率和生活垃圾无害化处理率有一定空间溢出效应.(4)"低经济-高福利"、"低经济-低福利"和"高经济-高福利"这三类城市最多,且分布较为均匀,而属于"高经济-低福利"类的城市最少.从提升路径来看,单边突破式是绝大多数城市弥补自身低效率阶段的最佳途径.
The Yangtze River Delta(YRD)urban agglomeration is an important engine of China's economic development.It is of great practical significance to explore the ecological welfare performance of the YRD for its high-quality development.From the perspective of resource allocation,under the transformed structure of ecological welfare performance consisting of ecology-economy-welfare,a two-stage chained super-efficiency DEA model considering the weak disposability of non-desired intermediate outputs was used to measure the global ecological welfare performance of the YRD urban agglomeration and the efficiency at different stages in 2011-2021.A spatial Durbin model with double-fixed effects was utilized to reveal the ecological welfare performance of the YRD urban agglomeration.The spatial spillover effect was also utilized to explore the improvement path of ecological welfare performance of the YRD urban agglomeration.The results show that:(1)The overall eco-welfare performance of the YRD urban agglomeration maintained a stable average level of around 0.8,but it was noteworthy that as high as 68.3%of the cities have not reached an effective state.At the same time,the significant differences in eco-welfare performance among cities reflected the uneven utilization efficiency of resources and also revealed the challenges and disparities in environmental protection and sustainable development efforts across different cities.(2)The internal composition of the YRD urban agglomeration exhibited disparities,with an ecological social-economic efficiency of 0.685 and an economic-welfare efficiency of 0.863.These disparities mainly came from imbalances within the three provinces and one city,contributing to rates of 77.39%and 77.14%,respectively.This unbalanced development presents challenges in terms of environmental protection,socio-economic integration,and welfare distribution.Therefore,targeted measures are imperative to foster balanced and sustainable development across the region.(3)Spatially,the ecological-welfare performance of the YRD urban agglomeration has strongly positive spatial correlation,while the greening coverage of built-up areas,the rate of harmless treatment of domestic waste,GDP per capita,urban per capita annual consumption,and government intervention have positive promotion effects on the regional integration of the YRD urban agglomeration,and the greening coverage of built-up areas and the rate of harmless treatment of domestic waste have certain spatial spillover effects.(4)The three categories of low economy-high welfare(L-H),low economy-low welfare(L-L),and high economy-high welfare(H-H)have the largest number of cities and are more evenly distributed.The number of cities belonging to the high economy-low welfare(H-L)category is the smallest.In terms of upgrading paths,unilateral breakthroughs are the best way for most cities to compensate for their inefficiency.
