中国肥料制造业全要素生产率的动态分析

运用非参数DEA—Malmquist指数方法估算中国各地区肥料制造业1998—2005年期间的全要素生产率增长、技术效率变化和技术进步情况,从而对中国各地区肥料制造业做全要素生产率分析。结果显示:在1998—2001年期间,全国和东部地区技术效率的改进对全要素生产率的变化贡献较大,而在后期技术进步则成为全要素生产率变化的主要动力;西部与东部地区情形相似,只不过技术进步成为全要素生产率变化的主要动力在2003年以后才表现出来;对于中部地区,可以说全要素生产率的提高一直主要依靠技术进步。

Total factor productivity of fertilizer manufacturing industry in China: a dynamic analysis

The paper applies nonparametric DEA-Malmquist index approach to estimating total factor productivity(TFP) growth,efficiency change and technological progress rate for the period from 1998 to 2005 of fertilizer manufacturing industry in China.The study indicates that efficiency changes in the cross-country and the eastern region is the key factor for TFP growth from 1998 to 2001,but technological progress has been the main driving force for TFP growth since 2002.The situation in the western region is similar to that in the eastern region;however,technological progress has been the main driving force for TFP growth since 2003.For the center region,TFP growth always depends on technological progress.
