文章基于数据包络分析(DEA)方法,测算了2003～2008年我国20个省份的全要素生产率(TFP),建立了基期和滞后一期的模型,通过实证分析得出,国际贸易活动对全要素生产率的影响不尽相同,进口贸易对全要素生产率有明显的促进作用,而出口贸易和外商直接投资都弱化了全要素生产率,并且这三个变量与全要素生产率的基期关系比滞后关系更显著。
Based on data envelopment analysis (DEA), this paper estimates the total factor productivity (TFP) of 20 provinces in China from 2003 to 2008 and establishes a model of the base period and the lagging period. Empirical analysis shows that the international trade activity to the whole The impact of factor productivity is not the same, import trade has a significant role in promoting total factor productivity, while export trade and foreign direct investment have weakened the total factor productivity, and the three variables and the total factor productivity than the lagging behind the relationship between the more Significant.
