中国省际全要素生产率及其持续增长

Provincial Total Factor Productivity in China and Its Sustainable Growth

基于DEA的Malmquist指数法,通过最新资本存量对我国30个省域经济(1978—2006)的TFP增速进行了测算,并对影响技术效率偏低的因素进行实证分析。①结果表明改革开放以来我国TFP保持了平均4.2%的增长,其中技术进步增长(3.5%)是推动TFP进步的主要因素,而技术效率增长偏低(0.6%);市场化和贷款比率对技术效率的提高有正向作用,行政管理成本严重负向影响技术效率,外资依存度和存款比率有较弱的负向影响。

Based on the method of DEA Malmquist index, this paper calculates the TFP growth speed of 30 provinces in China by using the new capital stock. Then further empirical analysis is made on the reasons for the low technical efficiency. The results show： the TFP maintained annual increasing by 4.2% since China＇s reform and opening up; and technological progress（3.5%） is the main factor which promote the development of TFP, while technical efficiency is low（0.6%）; marketization and lending rifio have a positive effect on improving the technology efficiency; administration cost has serious negative impact on technology efficiency; FDI and saving ratio has slight negative effect.
