以JK模型为理论基础,阐述国际分工深化提升生产性服务贸易竞争力的三条路径,通过对国际分工程度、生产性服务贸易竞争力以及将两者联接的三条路径选用合适指标量化,建立VAR模型,对国际分工深化到生产性服务贸易竞争力提升这一进程进行三条路径、两个层面的实证分析。研究发现,国际分工深化能够有效增加生产性服务业贸易需求,同时有利于发挥生产性服务业比较优势,但未能提升中国技术水平,然而此三条路径均可提升生产性服务贸易竞争力。
On the basis of JK model, this paper elaborates three paths of international division of labor deepening and enhancing the competitiveness of producer services trade. By means of quantifying the degree of international division of labor, the competitiveness of producer services and the three paths linking the two, we can establish a VAR model , The paper analyzes the three paths and the two levels of empirical analysis of the process of deepening the international division of labor and enhancing the competitiveness of producer services trade. The study found that the deepening of the international division of labor can effectively increase the demand for trade in productive services, and at the same time, it is conducive to giving play to the comparative advantages of producer services but fails to upgrade China’s technological level. However, all three paths can enhance the competitiveness of producer services.
