中国科技投入对经济增长的贡献率研究:1953-2001

The Contribution Rate of Science & Technology to the Economic Growth from 1953 to 2001

文章以国家统计局发布的1953-2001年度统计数据为基础,实证分析了中国科技投入与经济增长之间的关系。结果表明:(1)中国科技投入与经济增长之间存在着十分明显的单向因果关系,科技投入变化是引起GDP变化的原因;(2)在1953-2001年期间,科技投入对我国经济增长贡献率约为17 6%,表明科技投入在一定程度上促进了我国经济增长,但其促进作用并不是十分明显;(3)要加强科技投入在经济增长中的促进作用,不仅要关注增加科技投入的总量,更要重视优化科技投入的结构和提高科技资源的使用效率。

Based on the data from 195 3 to 2 0 0 1 released by the China Statistical Bureau ,this paper analyzes the relationship betweene conomic growth and ex penditure for science&technology .After detail research ,some resultshave been concluded :(1)The cause and effect relationship between economic growth and expenditure for science&technology from 195 3to 2 0 0 1is very close ,and the expenditure for science&technology is main causation that brings about economic growth ;(2 )The contribution rate of science&technology to economic growth is about17.6% ,this fact shows that the expenditure for science&technology drives the he economic growth ,but its function is not very distinct;(3 )To promote the economic growth ,we not only pay much attention the gross but also the structure and efficiency of the expenditure for science&technology.
