金融创新、产业结构升级与区域生态效率——基于空间计量模型及中介效应的实证分析

Financial Innovation, Industrial Structure Upgrading and Regional Ecological Efficiency—Empirical Analysis Based on Spatial Econometric Models and Mediating Effects

本文基于2012~2022年中国30个省级面板数据,运用多因子分析法和超效率SBM模型分别测度金融创新指数和区域生态效率,在此基础上,利用空间计量模型与中介效应模型实证分析金融创新对区域生态效率产生的影响。研究结果表明:金融创新水平的提高能够显著促进区域生态效率的提升,且存在区域异质性;金融创新对区域生态效率具有显著正向的空间溢出效应,本地区金融创新水平的提升将会推动相邻地区生态效率的提升;金融创新可以通过产业结构升级的中介效应促进区域生态效率的提升。This article is based on panel data from 30 provinces in China from 2012 to 2022. Multiple factor analysis and super efficiency SBM models are used to measure the financial innovation index and regional ecological efficiency, respectively. Based on this, spatial econometric models and mediation effect models are used to empirically analyze the impact of financial innovation on regional ecological efficiency. The research results indicate that the improvement of financial innovation level can significantly promote the improvement of regional ecological efficiency, and there is regional heterogeneity. Financial innovation has a positive spatial spillover effect on regional ecological efficiency, and the improvement of local financial innovation level will promote the improvement of ecological efficiency in adjacent regions. Financial innovation can promote the improvement of regional ecological efficiency through the intermediary effect of industrial structure upgrading.
