摘要
本文分析了估计生产率存在的内生性问题及其处理方法,并使用2000-2008年中国制造业企业数据,对全要素生产率进行了再估计。研究结果表明,使用Olley-Pakes(OP)扩展的方法之一Wooldridge-Levinsohn-Petrin(WLP)估计法会得到较为准确的全要素生产率估计值。利用WLP估计法计算的2007-2008年加总全要素生产率的增长率为0,即全要素生产率的增长出现了停滞;同时,劳动生产率的增长率在逐年增加,即资本和中间品投入对全要素生产率增长的贡献为负。
In this article,the author scrutinize the data from China Annual Survey of Manufacturing Firms( 2000-2008). After analyzing the problem of endogeneity and the method of treatment,it is found that Wooldridge-Levinsohn-Petrin estimation for total factor productivity( TFP) gives more accurate results than other methods. The aggregate growth rate of TFP from 2007 to 2008 is zero according to this estimation method,that is to say,the TFP has stagnated. On the other hand,the labor productivity experiences an obvious growth from 2007 to 2008,which means that the capital and median inputs,not the labor,contribute a negative factor to TFP.
