Abstract: Based on the enterprise micro data of Annual Survey of Industrial Firms in China, this paper studies TFPs of Manufacturing Industry and their difference and convergence among regions in China in term of OP model and convergence method. The following conclusions are made. First, on the whole, the overall TFP growth rate is 2.36% in the period from 2002 to 2011 while it is only-2.14% in the period from 2008 to 2011. Second, the TFPs are significantly different according to the regions, that is, the eastern coastal areas have relatively low rates of TFPs while the central and western regions have high ones. Third, the analysis of convergence indicates that there is neitherβconvergence norσconvergence among different regions, but there is club convergence among eastern, middle and western regions respectively. Finally, on the whole, capital growth rate and R&D have a significant positive impact on the growth of TFPs while the ratio of dependence on foreign trade is not significant.

摘要： 本文构建了技术进步内生的生产函数,并根据企业微观面板数据,采用OP模型和收敛模型测算了中国制造业全国层面及区域层面的全要素生产率,并分析了制造业全要素生产率的地区差异和收敛性。结果显示:2002~2011年中国制造业全国层面全要素生产率年均增长2.36%,受金融危机的影响,2008~2011年仅为-2.14%;在地区差异上,东部地区制造业全要素生产率要低于中西部地区;收敛分析显示,全域的全要素生产率既不存在β收敛也不存在σ收敛,但却存在“俱乐部”收敛,即中西部地区和东部地区内部各自收敛;同时,本文的分析还显示,资本增长率和研发投入都对全要素生产率的增长有显著正影响。
