电价水平与中国省际绿色全要素生产率关系实证研究

An Empirical Study on the Relationship between Electricity Price Level and China’s Provincial Green Total Factor Productivity

本文构建了全局参比SBM模型,以此测算了中国30个省份2006-2018年绿色全要素生产率,并利用2006-2018年省级面板数据实证检验了电价水平对中国省际绿色全要生产率的影响。研究发现:电价水平上升可以显著提升省际绿色全要素生产率,使用工具变量及滞后解释变量回归缓解内生性问题后结果稳健。进一步研究影响机制发现,电价水平上升可以通过缓解电价扭曲程度,推动产业结构升级,降低能源消费结构中煤炭占比,推广绿色生产技术的应用,进而促进绿色全要素生产率提升。此外电价水平对省际绿色全要素生产率的影响具有区域异质性,对于我国不同省份而言,电价对经济中等发达省份及二产占比中等省份的绿色全要素生产率的影响最大。

This paper constructs a global slacks-based measure(SBM)model to measure the green total factor productivity(GTFP)of 30 provinces in China from 2006 to 2018.And this paper empirically tests the impact of electricity price level on GTFP by using the provincial panel data from 2006 to 2018.The following results are found:The rise of electricity price can significantly promote the improvement of GTFP.The rise of electricity price can alleviate the distortion of electricity prices,promote the upgrading of the industrial structure,and reduce the proportion of coal in the energy consumption structure.And the rise of electricity price does not have a significant effect on innovation,but it will promote the application of green production technology.Furthermore,the impact of electricity price levels on GTFP has regional heterogeneity.For different provinces,electricity prices have the greatest impact on the GTFP of middle-developed provinces and the provinces with middle-level secondary industries.
