产品内国际分工的出现,将国与国之间基于比较优势地分工从“完整”的产品,贯彻到产品内部的工序和流程,从而极大地改变了全球经济运行方式。本文通过在传统国际分工理论中加入交易成本变量的方法,拓展了李嘉图模型,从而将传统贸易理论拓展到产品内国际分工的动因分析中,并通过中国省际面板数据的计量分析进行了实证检验。研究结果表明,产品内国际分工的完整动因应当是以比较优势的差异为基础,以交易成本的降低为条件。
The emergence of international division of labor in products greatly changes the way the global economy operates by applying the division of labor between countries based on comparative advantages from the “complete” product to the internal processes and processes within the product. This paper expands the Ricardian model by adding transaction cost variables to the traditional theory of international division of labor, so that the traditional trade theory can be extended to the motivation analysis of the international division of labor within the product and empirically tested through the econometric analysis of China’s provincial panel data . The results show that the complete motivation for the international division of labor within a product should be based on the difference in comparative advantage, subject to the reduction of transaction costs.
