国际贸易对技术效率影响的实证研究

The Empirical Research on the Effect of International Trade to Technical Efficiency

本文首先介绍了随机前沿分析方法,然后运用基于Panel数据的随机前沿模型测算了国际贸易在我国技术效率变迁中的影响,发现国际贸易对技术效率的提高有着明显的促进作用,其中外商直接投资的贡献最大,其次为进口贸易,最后为出口贸易。研究结果表明促进国际贸易,对于技术效率的提高有着十分重要的意义。

This paper introduces the stochastic frontier analysis method at first. Later, using stochastic frontier analysis models based on panel data, the paper calculates the effect of international trade to our country＇s technical efficiency. The research result discovers that international trade has improved technical efficiency significantly and the effect of the foreign direct investment is greatest, the import second and the export third. The result shows that the enhancement of international trade is important to the development of technical efficiency.
