1970后,国际分工开始以产品内分工为主,并且建立在此基础上的贸易形式日益见长。这类贸易形式以产品生产过程的分散化为基础,将生产过程分成若干个阶段,每个阶段又分别分散到不同国家进行生产,形成以生产工序、环节为对象的分工体系。由于这种分工体系的微观方面难以用贸易理论来解释,所以本文引入不完全契约理论,研究企业在生产组织方式选择中面临的问题。 Since 1970, the international division of labor has been dominated by intra-product division of labor, and the forms of trade established on this basis have become increasingly prevalent. Such forms of trade are based on the decentralization of the product manufacturing process, which divides the production process into several phases, each of which is dispersed to different countries for production, forming a system of division of labor for production processes and links. As the micro aspect of this division of labor system is difficult to explain with trade theory, this paper introduces the theory of incomplete contract to study the problems that enterprises face in the choice of production and organization methods.
