Study on the Influence of Smart City Construction on the Total Factor Productivity of Regional Construction Industry
Based on the panel data of 203 prefecture-level cities in China from 2007 to 2021,and on the basis of measuring the total factor productivity of the regional construction industry,this paper adopts a multi-period differential model to empirically-test the impact of smart city construction on the total factor productivity of the regional construction industry and further analyzes its mechanism.The empirical results show that:(1)the smart city construction has a significant positive promoting effect on the total factor productivity of the regional construction industry and the effect results are stable;(2)from the regional perspective,the promoting effect of smart city construction on eastern city is larger than that on the western city,and the effect on the western city is larger than that on the central city;(3)and in terms of city size,the promoting effect on the mega-cities and above are larger than that on the big cities and below.The mechanism test shows that smart city construction promotes the improvement of total factor productivity of regional construction industry through the effect of technological innovation and resource allocation.
