国际贸易与技术进步关系初探

本文主要从国际贸易与技术进步的关系的角度探讨技术进步的决定因素,在柯布—道格拉斯生产函数的基础上,用劳动生产率的增长代表技术进步的变化,同时将外贸依存度和外资依存度作为衡量技术进步的内生变量,采用1985-2004年的年度数据进行计量分析。本文的模型结论如下:(1)资本对经济增长的贡献要远大于劳动力的贡献;(2)国内投资对技术进步的促进作用要大于外商直接投资。因此,要想更快地发展我国经济,一方面要加大资本的投入,另一方面要加强自主创新,尤其是国内技术的自主创新,加强引进技术的消化吸收和利用。

On the Relationship between International Trade and Technology Progress

This paper studies the decisive factors of technology progress from the angle of the relationship between technology progress and international trade. During studying,increase of labor productivity is used to represent technology progress,and foreign trade dependence and foreign capital dependence are used to weigh technology progress. On the basis of C-D production function,data from 1985 to 2004 were analyzed. The results are as follows: (1) economic growth is more dependent on capital than labor; (2) compared with foreign investment,national investment more promotes technology progress.The conclusion is: to develop its economy more fast,China should increase investment and strengthen innovation,that is strengthening national technological innovation and technological utilization.
