改革开放后我国农村地区的分工演进——基于新兴古典经济学的分析框架

On Evolution of Division of Labor in the Rural Area Of China since Economic Reform——Based on the Framework of New Classical Economics

改革开放后,我国农村地区取得了综合发展,而经济发展的轨迹是斯密定理和杨格定理交替作用的过程,不断地重复着"分工深化—市场扩展—分工深化"的循环。根据新兴古典经济学的分析框架,当交易效率上升时,则人们会选择高一些分工水平,通过众多不同农户之间的分工,使得利用专业化经济和利用迂回生产的效果能够兼顾,从而提高农民和农村地区的交易效率。对我国农村地区1979-1999年的实证分析也说明了农民人均收入与商品化程度及分工水平有正相关关系。

The economy of Chinese rural area has been greatly developing since 1978. The process of economic development is continuous cycle of Smith and Young Theorem, which is evolution of division-market extension-evolution of division. This research analyzes the evolution of division of labor in the rural area of China with the framework of new classical economics. Through division among different peasant households, specialization and roundabout production are worked, then transaction efficiency will be improved. Data during 1979 to 1999 in the rural area explain that per capita income of peasant and degree of commercialization are positively related.
