利用西部地区1992—2009年的面板数据,基于Malmquist指数法,考察了西部大开发战略实施前后各地区全要素生产率的变化。结果表明:大开发战略的实施使得西部地区全要素生产率的增长总体上由负值(-0.8%)转为正值(1.7%),全要素生产率对经济增长的贡献由-8.8%提高到14.3%,对东部地区的追赶效应明显,但仍存在较大差距。
Using the Malmquist productivity index, we have analyzed the total factor productivity change(TFP-Ch)from the perspective of the western region development strategy based on the panel data from 1992 to 2009. The study finds that, TFP growth rate of western region form --0. 8% during the period of 1992-2000 up to 1.7~//00 during the period of 2001-- 2009, and the TFP affects significantly on economic growth from --8.8 % to 14.3% after the western region development strategy implementation.
