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

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.
