产品内国际分工的内在动因——理论模型与基于中国省际面板数据的实证研究

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。

Research on the Intrinsic Cause of Intra-Product Specification

The emergence of intra previous specialization principle, which states, from the whole product to its -product specialization not only alters the is based on comparative advantage between working procedure and process, but also changes the global economic running mode greatly. With the method of adding the exchange cost variable in the traditional international specialization model to exten-- ding the Ricardian Model, this thesis uses the traditional trade theory to discuss the cause of intra-product specialization and makes empirical analysis with the panel data of most provinces in China. The research result shows that the comprehensive reason of intra-product specialization should take the comparative advantage difference as its basis, and the exchange cost reduction as its key condition.
