技术扩散与收入收敛的新古典框架分析

Analysis of Technology Diffusion and Income Convergence Based on Neoclassical Frame

有关地区收入差距成因的研究一直是理论探讨的热点,但多数研究只关注资本、劳动等因素而忽视了技术差异所起的作用。通过一个两部门的新古典模型来考察技术扩散与收入收敛之间的关系,结果表明技术差异是收入差距的重要原因之一。在模型达到均衡的条件下,根据技术的初始引进费用不同,地区之间的收入可能完全收敛、完全不收敛和部分收敛三种情况。在部分收敛的阶段,经济处于二元状态,这个结论是和我国的现实相一致的。

The research on the regional income difference has been hot on in theoretical exploration, but most of the researchers focus on the labor or capital differences when studying the regional income difference and leaving out the technology difference between regions, This paper sets up a neoclassical model to study the technology diffusion and income convergence. In the competitive equilibrium of the model and on account of the different initiate costs of introduction, three types of income convergences among the regions can be concluded： complete lack of convergence, partial and complete convergences. In the stage of partial convergence, economy is dualistic, which is consistent with that of our country.
