Analysis and Research on the Impact of Productive Service Agglomeration on Green Total Factor Productivity of Service Industry Based on the Moderating Effect of FDI

Abstract

This paper selects the GML index to measure the green total factor productivity of China's service industry, and empirically examines the effects of productive service industry agglomeration, service industry FDI and their interaction terms on green total factor productivity after fully controlling for the important variables affecting green total factor productivity in service industry. At the regional level, there is regional heterogeneity in the moderating effect of service industry FDI on green TFP, and the joint effect of the two significantly promotes green TFP in the eastern region and negatively affects the central region.
