经济结构变化和经济增长

本文试图从生产技术角度构建一个多部门的经济增长模型,同时容纳Kuznets事实和Kaldor事实。模型经济由最终部门和多个中间部门组成,最终产品由各中间产品以CES函数形式生产。各中间部门的技术增长率不同,而这种差异引起经济结构变化,并导致中间产品的相对价格变化,进而决定各中间部门之间要素流动和产值相对份额变动。最终产品的技术增长率为各中间部门的技术增长率加权平均和,并随经济增长单方向变动,变动方向与中间产品之间的替代弹性大小相关。

STRUCTURAL CHANGE AND ECONOMIC GROWTH

This paper constructs a multi-sector model of growth with differences in TFP growth rates across intermediate sectors that accommodates both the Kaldor and Kuznets facts.The different levels of technology among intermediate sectors bring changes to the relative prices of the intermediate goods,and then cause reallocation of labor in those sectors.TFP growth rate in the final product sector is determined by the structure of the intermediate sectors.It changes monotonically as the economy grows,and its direct...
