建立广义动态空间面板计量模型,从本地效应和区际互动双重视角分析产业结构优化升级对省份生态效率影响的驱动机理和作用效果。研究发现,产业结构高度化既能提高本省份也能提高其他省份的生态效率,即存在本地和外部双重正面效应;而产业结构合理化对生态效率则更多体现为正外部效应。从异质性上看,经济发展水平的提高,更加有利于合理化本地正面效应以及高度化双重正面效应的发挥;合理化和高度化与环境规制的相互作用,更有利于本省份生态效率的提高。
A generalized dynamic spatial panel measurement model is established. The driving mechanism and effect of the industrial structure optimization and upgrading on the provincial ecological efficiency are analyzed from the perspective of local effect and inter-regional interaction. The study found that the industrial structure can not only improve the province but also improve the ecological efficiency of other provinces, that is, there are both local and external positive effects; and the industrialization of the rationalization of the ecological efficiency is more reflected in the positive external effects. In terms of heterogeneity, raising the level of economic development is more conducive to rationalizing the local positive effect and exerting a dual positive effect. The interaction between rationalization and elevation and environmental regulation is more conducive to the improvement of eco-efficiency in the province.
