摘要
采用基于DEA的Malmquist指数方法对2002～2007年我国制造业全要素生产率、技术效率与技术进步进行了分析,在此基础上利用28个行业面板数据,从总体和行业分组两个层面考察了进口和出口对制造行业全要素生产率及其分解变量的影响。结果发现,在2002～2007年期间,我国制造业全要素生产率的增长主要依赖于技术进步水平的提升,而非技术效率的增长。从制造业总体回归来看,进口对全要素生产率和技术进步增长有显著的正向作用,出口则阻碍了全要素生产率和技术进步的增长;进出口对技术效率的影响都为正,其中进口对技术效率的影响不显著,而出口的影响显著。行业分组回归表明,进出口贸易对不同行业生产率增长的影响程度不一样。
The paper computes Malmquist productivity index,technical efficiency index and technical progress index of our country＇s manufacturing industry from 2002~2007 by DEA .At the same time, based on the panel data of 28 manufacturing sub-sectors, the authors analyze the influence that imports and exports on Malmquist produetivity index, technical effieieney index and technical progress index from manufacturing industry and industry groups. The paper finds that China＇s total factor productivity growth of manufacturing industry is mainly due to the enhancement of technologieal level, rather than technical efficiency. The overall regression results of manufacturing industry shows that imports have a significant positive effect on the growth of total faetor produetivity and technological progress, exports hinder the growth of total factor productivity growth and technological progress. The regression results of industry groups shows that the import and export trade have a different influence on produetivity growth in different sectors.
