In order to further improve total factor productivity,an empirical analysis was conducted on the impact of industrial integration on total factor productivity in manufacturing and service enterprises in 30 provinces of China from 2014 to 2023.Specifically,total factor productivity was selected as the dependent variable,industrial integration level as the independent variable,and economic development level,human capital level,foreign direct investment level,infrastructure improvement level,and market competition level as control variables.The impact of industrial integration on total factor productivity was verified through descriptive statistics,regression analysis,robustness testing,and heterogeneity analysis.The results show that industrial integration significantly promotes the improvement of total factor productivity,and is significant at the 1% level.Industrial integration first suppresses the improvement of technological efficiency and then promotes it,and is significant at the 1% level.The role of industrial integration in promoting technological progress shows a single positive linear effect;The impact of industrial integration on total factor productivity in the eastern,western,and central regions is the same,all showing a significant positive promoting effect,and significant at the 1% level.On this basis,in order to further promote the improvement of total factor productivity and fully leverage the promoting role of industrial integration,it is proposed to accelerate the process of industrial integration and steadily promote industrial integration;improve the level of economic development and strengthen the construction of talent system;suggestions and countermeasures for improving the level of foreign direct investment and promoting healthy market competition.
