目前中国制造业技术创新能力较弱，仍处于全球价值链分工体系中低端。而生产性服务贸易可以有效地促进制造业发挥规模经济的作用，有助于制造业发展，进而提升其生产效率和资源的充分利用程度。在了解生产性服务进口对制造业升级影响的理论机制基础上，根据2000-2022年的数据，研究生产性服务贸易进出口对我国制造业国际竞争力的影响，采用时间序列数据进行OLS回归分析，结果表明生产性服务贸易从整体上对我国制造业国际竞争力有提升作用，生产性服务进口对中国制造业竞争力的影响比生产性服务出口要大。最后就促进我国生产性服务贸易的发展与制造业竞争力的提升提出相应的对策建议。

At present, China's manufacturing technology innovation ability is weak, and it is still in the middle and low end of the global value chain division of labor system. Productive service trade can effectively promote the manufacturing industry to play the role of scale economy, contribute to the development of the manufacturing industry, and then improve its production efficiency and the full utilization of resources. On the basis of understanding the theoretical mechanism of the impact of imports of productive services on the upgrading of manufacturing industry, based on the data from 2000 to 2022, this paper studies the impact of imports and exports of productive services trade on the international competitiveness of China's manufacturing industry, and adopts time series data to conduct OLS regression analysis. The results show that productive services trade can improve the international competitiveness of China's manufacturing industry on the whole. The import of productive services has a greater impact on the competitiveness of China's manufacturing industry than the export of productive services. Finally, this paper puts forward some countermeasures and suggestions for promoting the development of productive service trade and enhancing the competitiveness of manufacturing industry.
