Abstract: Manufacturing servitization is an important direction to realize the high-quality development of the manufacturing industry. Based on the measurement of the servitization and openness of China’s manufacturing industry, this paper makes an empirical test on the relationship between the servitization of the manufacturing industry and the international division of labor of the manufacturing industry, as well as the regulatory effect of the opening-up of the service industry by using the data of the microcosmic enterprises. The results show that the servitization of the manufacturing industry is generally conducive to the improvement of the status of international division of labor, and that the opening-up of the service industry can enhance the promotion effect. The heterogeneity analysis reveals that the wholesale and retail servitization, the financial and insurance servitization and the professional science and technology servitization can all significantly improve the status of international division of labor of the manufacturing industry, while the transportation servitization and the information and communication servitization will inhibit the status of international division of labor of the manufacturing industry.The servitization of the manufacturing industry plays the strongest role in the technology-intensive manufacturing industry and the weakest role in the labor-intensive manufacturing industry. In terms of the action mechanism, technology spillover plays an intermediary role in the process of the servitization of the manufacturing industry affecting the status of international division of labor of the manufacturing industry.

Key words: servitization of manufacturing industry, opening-up of service, status of international division of labor, regulatory effect
