财政科技投入对经济增长的影响——基于研发(R&D)支出的实证分析

Influence of Financial Investment in Science and Technology on Economic Growth——Based on Empirical Analysis of R&D Expenditure

通过对中国1995-2009年财政科技投入数据的分析,可以发现,中国研究与发展经费(R&D)支出总量不大,研发支出占GDP的比重低于世界上许多国家。随后,利用计量经济学中的GMM回归方法,分析得出财政科技投入在一定程度上可以促进经济发展,但基础研究、应用研究与试验发展三类支出对经济增长的作用方向不同,应用研究与试验发展会阻碍经济增长,而基础研究投入将促进经济增长。最后,根据回归结果,提出为了实现"十二五"规划目标,需要加大财政科技投入力度、调整财政科技投入结构,促进经济发展方式的转变。

This paper analyzes the financial investment in science and technology data from 1995 to 2009,finding out that China has a small quantity of R&D expenditure and the proportion of R&D expenditure to GDP is lower than that of many other countries around the world.By using GMM regression of econometrics,the author discovers that financial investment in science and technology could,in a certain degree,promote the development of economy,but the basic research,applied research and experimental research have different influences on the economic growth.The basic research and experimental research would hinder the economic growth,while the basic research would,with no doubt,motivate the economic growth.In conclusion,according to the regression result,this paper comes out with the view that in ovder allonplish the goal of the Twelfth Five-year Plan,China should increase financial investment in science and technology,adjust the structure of financial technology input and accelerate the transformation of economic development.
