生产性服务贸易自由化与新质生产力发展:理论机制与经验证据OACHSSCD

The liberalization of productive service trade has gradually become a new driving force for promoting the develop-ment of new quality productivity through the establishment of a global collaboration network.This paper takes the data of 30 prov-inces in China from 2014 to 2024 as samples to empirically test the impact and mechanism of the liberalization of productive ser-vice trade on the development of new quality productivity.Research finds that the liberalization of trade in productive services can positively promote the development of new quality productivity,and this conclusion still holds true after endogeneity and robust-ness tests.Heterogeneity test results show that compared with non-free trade pilot zones and inland regions,the liberalization of productive service trade has a more significant promoting effect on the development of new quality productivity in free trade pilot zones and coastal regions.The mediation effect test results show that the agglomeration of high-tech manufacturing industry and the quality of intermediate goods play a mediating role in the process of promoting the development of new quality productivity through the liberalization of productive service trade.The analysis results of the spatial spillover effect show that the liberalization of productive service trade has a positive spatial spillover effect on the development of new quality productivity.
