Based on the input-output table and socio economic accounts of World Input-Output Database (WIOD), and based on the scientific measurement of manufacturing servitization and three types intermediate import dependence of manufacturing industry, and leading into the interaction between technology distance and scale effect and manufacturing servitization, deeply analyzes the mechanism of manufacturing servitization on the import of three types of intermediate goods, and further analyzes the mechanism of manufacturing servitization and the import of intermediate goods on total factor productivity. It is found that: ① Manufacturing servitization will aggravate the import dependence of manufacturing intermediates and alleviate the import dependence of production service and service intermediates. This conclusion is robust in multi-dimensional test. ② With the introduction of technological distance, the marginal effect of manufacturing servitization on the import dependence of manufacturing intermediate goods and production service intermediate goods is inverted U-shaped, and the technological distance will affect the marginal effect of manufacturing servitization. ③ The expansion of industry scale can effectively alleviate the import dependence of manufacturing intermediates, and with the improvement of manufacturing service, the mitigation effect of manufacturing intermediates import dependence is strengthened. ④ Import dependence of three types of intermediate goods in manufacturing can effectively improve the total factor productivity of a country.
