Abstract: The liberalization of international trade makes many enterprises choose to transfer their industries to countries or regions with lower costs, which means that the impact of imports will lead to the loss of jobs in China's manufacturing industry. Through theoretical logic analysis and empirical test, it is confirmed that the manufacturing industry can effectively mitigate the negative impact of the import shock on China's manufacturing employment through service, and the empirical test confirms the positive regulatory role of service, and the employment effect caused by the import shock and the mitigation role of service are mainly reflected in the heavy industry sector, Further analysis also shows that there is significant heterogeneity in the role of service of different business types. When the manufacturing industry faces the impact of import, the demand and supply of labor force in the industry will be affected. Studying the mechanism will help to better understand the regulatory role of manufacturing service in this.

Key words: manufacturing employment scale, import shock, servicification, industrial relocation
