要素市场扭曲如何影响绿色全要素生产率——基于地级市经验数据研究

How Does Factor Market Distortion Affect Green Total Factor Productivity?Research on Empirical Data of Prefecture-level Cities

基于SYS-GMM估计方法对要素市场扭曲影响绿色全要素生产率进行实证分析,并运用交互项方法探究了不同区域要素市场扭曲对不同企业特征的绿色全要素生产率影响的宏微观差异。研究发现:要素市场扭曲对绿色全要素生产率呈现显著抑制作用,且是通过效率改进和技术进步中介效应渠道实现的;在企业微观特征所产生对要素市场扭曲抑制绿色全要素生产率的冲抵效应中,企业规模较大、具有非国有企业性质、企业创新能力高及资本集聚程度较低的企业,在一定程度上可以增强企业微观特征所产生的冲抵效应;而企业异质性特征在各区域所产生对要素市场扭曲抑制绿色全要素生产率的冲抵或增加效应因资源禀赋差异表现不尽相同;企业规模和创新能力的冲抵效应在东部地区表现较强,资本集聚程度的增加效应则在中部地区表现较强。

This paper uses SYS-GMM estimation method to empirically analyze how factor market distortion affects green total factor productivity,and uses interactive term method to explore the macro-micro difference of influence of factor market distortion on green total factor productivity of different enterprise characteristics in different regions.The study finds that the factor market distortion has a significant inhibitory effect on green total factor productivity,and is achieved through the channel of efficiency improvement and technological progress mediation.In the offset effect of the micro-features of the enterprise on the factor market distortion and the suppression of green total factor productivity,enterprises with large scale,non-state-owned enterprises,high innovation ability and low capital accumulation can enhance the offset effect of micro-features of enterprises to a certain extent.However,the offset effect or increase effect of enterprise heterogeneity characteristics on factor market distortion inhibiting green total factor productivity in different regions is not the same due to resource endowment differences.The offset effect of firm size and innovation ability are strong in the eastern region,while the increase effect of capital agglomeration is stronger in the central region.
