近来国外的许多研究利用现代经济增长理论的分析框架,从理论上探讨了结构转变对经济增长的重要性。但相关模型设定不尽符合我国二元经济的现实。本文结合我国实际、通过拓展相关理论模型,构建包含两个代表性个体、考虑劳动力转移成本和政府投入的二元经济增长模型,从理论上探讨我国结构转变与经济增长的关系,指出了政府投入对促进结构转变、加快经济增长的关键作用。进一步,本文还利用该模型解释了经济增长过程中的区域差距和城乡差距的变动,并探讨缩减经济差距的相关对策。 The recent the oretical literatures on economic growth have focused mostly on structural change that accompanies the growth process. But some assumptions are not accurate descriptions of the dual economy of China。 This paper follow s the idea of Mat suyama ( 1992) to construct a growth model of the dual economy with two representative agents, in which the cost of sector a labor transfer and government spending are considered。 Such a growth model is more suitable to the analysis of Chinese economic development。We show that government spending plays a key role in structural change and economic growth。 Furthermore, the model developed here is also used to explain the change of the regional disparity and rural urban income differences in the growth process。国家社科基金项目(07BJL017);福建省社科重点项目(2006A005
