R&D的投入对GDP增长贡献的定量与实证分析

The Quantitative and Positive Analysis of the Contribution about Research and Development to Economic Growth

近年来R&D(研究与试验发展)在社会经济发展中的作用越来越重要,本文基于索洛模型提出用于测度研发(R&D)投入对GDP贡献的定量分析模型,最后利用我国近十年的数据对模型作实证分析,得出我国十年来研发投入对GDP贡献率呈现平稳增长态势,但贡献率较低。

This paper has given an analysis of the importance of R＆D input to economic growth, and then the passage gives the quantitative and positive analysis of it＇s contribution to economics growth on the base of the models which is derived from R.M.solow models . At the end of the passage, It used the data of recent years as an example to give positive analysis , and the result is that the contribution about R＆D to economic growth is on a steady rate in recent years . But the rate is still lowly.
