生产性服务业集聚对绿色全要素生产率的影响——基于不同集聚视角下面板门槛模型的实证分析

基于产业集聚的理论研究和绿色发展的环境诉求,本文以2004-2016年中国30个省(市)的绿色全要素生产率为研究样本,运用面板门槛模型探讨供给侧视角下生产性服务业集聚对绿色全要素生产率的影响,从专业化集聚和多样化集聚角度证实了生产性服务业集聚对绿色全要素生产率存在结构突变效应,并鉴于内部细分行业集聚特征展开进一步探讨。结果表明:在不同集聚视角下,能源强度、经济发展水平对绿色全要素生产率存在不同程度的门槛效应;就全国层面,专业化集聚对绿色全要素生产率具有一定程度上的抑制作用,多样化集聚表现出较明显的促进作用;就行业层面,细分行业专业化集聚存在明显的行业异质性特征,金融业是提升绿色全要素生产率的重点行业。

The Impact of Producer Services Agglomeration on Green TFP:An Empirical Analysis of Panel Threshold Model based on Different Agglomeration Perspectives

Based on the theoretical research of industrial agglomeration and the environmental demands of green development,this paper takes the green total factor productivity of 30 provinces(cities)in China from 2004 to 2016 as the research sample,uses the panel threshold model to explore the impact of producer service industry agglomeration on green total factor productivity from the perspective of supply side,proves that producer services agglomeration has structural mutation effect on green total factor productivity from the perspective of specialization agglomeration and diversification agglomeration,and further discusses the characteristics of internal industry segmentation agglomeration.The results show that in different perspectives of agglomeration,energy intensity and economic development level have different threshold effects on green TFP;at the national level,specialized agglomeration has a certain degree of inhibition on green TFP,and diversified agglomeration shows a more obvious role in promoting it;at the industry level,specialized agglomeration of subdivided industries has obvious characteristics of industry heterogeneity,and financial industry is the key industry to enhance green TFP.
