行政等级与城市规模对生态福利绩效的影响研究

基于广义数据包络分析法（DEA）和随机抽样Bootstrap法，使用2015—2018年全国288个地级及以上城市的面板数据，研究行政等级、城市规模对生态福利绩效的影响，分析城市规模在行政等级影响生态福利绩效中的路径作用。结果表明：我国288个地级及以上城市的生态福利绩效水平整体均值不高，但随时间推移呈上升趋势且近年来增速逐渐加快；行政等级和城市规模均对生态福利绩效起显著正向影响，技术进步显著提升城市的生态福利绩效，外资依存度显著降低城市的生态福利绩效；城市规模是城市行政等级影响生态福利绩效的重要路径，行政等级越高，城市规模越大，生态福利绩效水平越高。基于以上结论，为协调经济、环境、社会实现可持续发展提出政策建议。

The influence of administrative hierarchy and urban scale on ecological well-being performance

As the urbanization process accelerates, more and more urban population continues to release kinetic energy for social development. But at the same time, they bring many resource and environmental problems, intensifying the contradiction between the rapid urban development and the natural environment. Nowadays, it is inevitably an important period of in-depth development of urbanization, alleviating resource and environmental contradictions, economic transformation and upgrading, and accelerating the promotion of socialist modernization. How to achieve sustainable urban development has become a very urgent and important issue. This paper, from the perspective of Chinese characteristic administrative level, explores the impact of administrative level and city size on ecological welfare performance. This study is helpful to understand the change trend of ecological welfare performance and the formation of its heterogeneity under the "government intervention + market promotion" model. It can also provide useful policy implications for the choice of urban sustainable development strategies in China, which is of great significance to deepen sustainable development research. Based on the generalized data envelopment analysis (DEA) method and random sampling bootstrap method, using the panel data of 288 prefecture level and above cities in China from 2015 to 2018, this paper studies the impact of administrative hierarchy and urban scale on ecological well-being performance, and analyzes the path role of urban scale in the impact of administrative hierarchy on ecological well-being performance. Main conclusions are as follows: (1) 288 prefecture level and above cities in China are at overall low level of ecological well-being performance, but show an upward trend over time, and the growth rate has gradually accelerated in recent years. (2) Both administrative hierarchy and urban scale have a significant positive impact on ecological well-being performance. Technological progress significantly improves urban ecological well-being performance, and FDI dependence significantly reduces urban ecological well-being performance. (3) Urban scale is an important path for administrative hierarchy to affect ecological well-being performance. The higher administrative level will bring larger urban scale and higher level of ecological well-being performance. Finally, based on the above conclusions, policy suggestions are provided for coordinating the sustainable development of economy, environment and society.
