科技投入与经济增长:基于我国沿海三大经济区域的实证分析

Science & Technology Input and Economic Growth: An Empirical Analysis Based on the Three Major Coastal Economic Regions of China

科技投入与经济增长之间存在密切关系。根据我国沿海三大经济区域经济增长与科技投入的数据,首先对沿海三大经济区域经济增长与科技投入做了灰色关联度分析,然后建立计量经济学模型进行进一步研究。对三大经济区域科技投入对经济增长的贡献度做了分析与比较。研究认为,在我国沿海三大经济区域中,长三角地区在各项指标中几乎都处于领先地位;我国沿海三大经济区域的经济增长与科技活动人员之间的关系最为密切,其次是科技活动经费支出,再次是R&D经费支出;珠三角地区经济增长率与科技活动经费增长率及R&D经费支出增长率之间的关系较为微弱。

There is close relationship between science technology inputs and economic growth.Based on the data of science technology input and economic growth of the three major coastal economic regions of China,firstly the paper makes the gray correlation analysis on the economic growth and science technology input of the three major coastal economic regions of China,and then builds econometric models for further study.The paper analyzes and compares the contribution rate of science technology inputs to economic growth of the three major economic regions.The study shows that in the three coastal economic area of China,the Yangtze River Delta region is in the leading position in almost all the indicators;there is the closest relationship between economic growth and science technology activities in the three mayor coastal economic regions of China,followed by economic growth and science technology activities expenditures,then,is RD expenditures;there is relatively a weak relationship between economic growth rate,the growth rate of science technology activities expenditures and the growth rate of RD expenditures in Pearl River Delta region.
