环境规制、媒体关注与绿色全要素生产率——来自省级面板数据的分析

Environmental Regulation,Media Attention and Green Total Factor Productivity:An Analysis Based on Provincial Panel Data

基于2004—2019年中国省级面板数据,采用固定效应模型实证考察了环境规制与媒体关注对绿色全要素生产率的影响。结果表明,以工业“三废”排放量衡量的命令控制型环境规制强度的提升能有效促进绿色全要素生产率的提升,媒体关注可以强化环境规制对绿色全要素生产率的促进作用。异质性分析发现,环境规制和媒体关注对中部地区绿色全要素生产率的影响尤为显著。作用机制分析表明,环境规制主要通过影响各地的技术创新水平,促进绿色全要素生产率的提升;媒体关注会强化环境规制对地区技术创新的促进作用,进而强化环境规制与地区绿色全要素生产率之间的关系。

Based on China’s provincial panel data from 2004 to 2019,this paper employs a fixed effects model to empirically examine the impact of environmental regulation and media attention on green total factor productivity (GTFP).The results show that the increase in the intensity of command-and-control environmental regulations measured by industrial “three wastes” emissions can effectively promote the improvement of GTFP,and media attention can strengthen the role of environmental regulations in promoting GTFP.The analysis of heterogeneity indicates that environmental regulations and media attention have a particularly significant impact on GTFP in the central region.Further analysis on the mechanism reflects that environmental regulation mainly promotes the improvement of GTFP by influencing the level of technological innovation in various regions;media attention can strengthen the promotion of environmental regulation on technological innovation,thereby enhancing the relationship between environmental regulation and regional GTFP.
