摘要
研究与发展(R&D)投入对经济增长的作用日益显著,已经有不少学者对R&D投入与经济增长关系进行过研究。依据浙江省1990—2008年的统计数据,对R&D投入与经济增长两个变量进行了ADF平稳性、协整和格兰杰因果关系检验,建立两者之间的误差修正模型。研究结果表明:R&D投入与经济增长之间存在长期的均衡关系;R&D投入是经济增长的格兰杰原因,但经济增长尚不是研发投入增加的格兰杰原因。这说明R&D投入对浙江省经济增长起到一定的推动作用,但经济增长并没有带来R&D投入的大幅增加。
The effect of R ＆ D （Research and Development）. It studied by numerous academic scholars, is playing more important role in economic growth. We based on 1990--2008 statistics, Zhejiang province, on the R ＆ D investment and economic growth of these two variables were ADF stationary test, co- integration test and Granger causality test to establish the difference between the error correction model. The results show that R ＆ D investment and economic growth in the long -term equilibrium relationship, R ＆ D investment Granger cause economic growth, but economic growth is not Granger cause the increase in R ＆ D investment. This shows that R ＆ D investment on economic growth in Zhejiang province has played a certain role, but e- conomic growth has not brought R ＆ D investment increased significantly.
