市场分割降低了地区环境全要素生产率吗?——基于地理加权回归模型的实证研究

Have Market Segmentation Reduced Regional Environmental Total Factor Productivity?——Based on Geographically weighted Regression Model

采用1998-2012年的省级数据,利用能考虑空间异质性的地理加权回归模型,研究了市场分割对地区环境全要素生产率的影响。研究发现市场分割对地区环境全要素生产率并非存在完全的负向效应,而是存在差异化的影响,在市场分割程度较低的地区,市场分割有利于环境全要素生产率提升;但是,在市场分割程度较高的地区,市场分割却对环境全要素生产率产生了负面影响,且随着市场分割的加剧,表现出同步的上升趋势。进一步研究发现,市场分割对环境全要素生产率影响的空间异质性主要由环境技术进步率体现出来。

Based on provincial data from 1998 to 2012,the article studies the market segmentation impact on the regional environmental total factor productivity through the geographically weighted regression model, which features the spatial heterogeneity. The study finds that market segmentation has no completely negative but different effects on the regional environmental total factor productivity. In the areas with lower degree of market segmentation,market segmentation benefits the total factor productivity; while in the areas with higher degree of market segmentation,market segmentation has negative effect on the total factor productivity;and the higher degree of market segmentation,the greater negative effect.Further study finds that,the spatial heterogeneity of the impact of market segmentation on environmental total factor productivity is mainly reflected in environmental technology progress rate.
