对偶法核算全要素生产率

 在Griliches、Jorgenson（1967）和Hsieh（1999，2002）的基础上，结合卢卡斯（1988）的人力资本模型发展了一种基于人力资本的对偶法测度全要素生产率。以改革开放以来的上海为研究对象，同时运用对偶法和传统测度方法测度上海市全要素生产率，验证了经济增长率的变动更多来自于全要素生产率而不是投入要素的变动，同时发现两种方法测度结果差异显著。经过进一步分析，发现这种差异来源于直接资本价格与间接资本价格之间存在着高度的不一致性。通过对两种方法的适用性进行讨论，可以认为对偶法是传统测度方法一种有益的补充。

Accounting Total Factor Productivity with Dual Method

In order to measure total factor productivity, this paper developed a new endogenous dual method which combined with Lucas (1988) human capital model. Regarding Shanghai after the reform and opening up as research object, it applied dual method and the traditional method to measure TFP. The results verified changes in the economic growth rate counting more on total factor productivity growth than on changes in input factors. It also found that the results measured by two methods had significant differences. Through further analysis, we found this difference came from inconsistency between the direct and indirect price of capital. Through discussing the applicability of the two methods, we found that the dual method should be a useful supplement for the traditional method.
