Abstract

In this study, we used the super-efficient global slacks-based measure of directional distance functions (SBM-DDF) model to evaluate the ecological efficiency and changes in 12 provinces in western China between 2006 and 2020. We then used two linear and nonlinear regression models to analyze in detail the influence mechanisms of different industrial agglomeration forms on the local ecological efficiency. The results show the following: the overall ecological efficiency in the western China region shows a dynamic upward trend. The ecological efficiency of western China is quite different, with the overall characteristics of “high in south and low in north”, “slow in south and fast in north”, and “three-way polarization.” Different types of industrial agglomeration in western China have obvious differences in terms of ecological efficiency. Both specialized agglomeration and unrelated diversification agglomeration in western China have a significant negative impact on ecological efficiency. The relationship between agglomeration-related diversity and ecological efficiency in the western region is of the “U” type. This study’s results can also provide a reference for the formulation of industrial transformation and ecological protection policies in the implementation process of the second round of the western development strategy. This study thus has fundamental significance in the promotion of the second round of western development work.
