摘要:  推动区域市场一体化,提高生态效率是实现区域经济高质量发展,发展低碳经济的重大举措。收集2009~2020年长三角地区41个城市的面板数据,使用系统GMM、调节效应模型和门槛效应模型,实证分析市场一体化对生态效率的影响效应。研究结果发现:市场一体化有助于提升长三角城市群的生态效率,影响效应在时间、地区属性以及市场类型上存在显著的异质性特征;政府生态环境注意力在市场一体化影响生态效率的作用中起到正向的调节效应;产业结构优化在市场一体化作用于生态效率的过程中起到了门槛效应。因此,提升政府生态环境注意力,优化产业结构是提高生态效率的有效途径。不断推进区域市场一体化建设,对提高长三角地区的生态效率,推进环境治理协同发展具有重要意义。

Abstract: Enhancing regional market integration and augmenting ecological efficiency are crucial strategies for the advancement of regional economic quality and the cultivation of a low-carbon economy. A comprehensive dataset incorporating panel data from 41 cities in the Yangtze River Delta region was compiled. The dataset covered the period from 2009 to 2020. Subsequent empirical analyses were conducted to examine the impacts of market integration on ecological efficiency. System GMM, regulatory effect model, and threshold effect model were applied in this study. The findings indicated that market integration was beneficial for enhancing the ecological efficiency of the Yangtze River Delta urban cluster. The influence exhibited notable heterogeneity across different periods, regional characteristics, and market categories. The government's focus on eco-environment exerted a positive regulatory role on the relationship between market integration and ecological efficiency. Moreover, the optimization of the industrial structure served as a threshold effect amidst the dynamics of market integration's impact on ecological efficiency. Consequently, the optimization of the industrial structure and the intensification of the government's focus on the eco-environment constituted effective strategies for enhancing ecological efficiency. The sustained promotion of regional market integration is instrumental in bolstering the ecological efficiency of the Yangtze River Delta region and fostering coordinated environmental governance development.
