摘要
通过协整检验、Granger因果关系检验、脉冲响应函数及方差分解等计量经济分析方法,利用1991—2008年度安徽省经济数据对科技投入与经济增长的关系进行了实证分析。分析表明:科技投入与经济增长之间具有双向的Granger因果关系;科技投入冲击对经济增长有正向的脉冲响应影响;对经济增长的贡献率平稳增加。
The paper focuses on the empirical analysis about the relationship between the science and technology input and the economic growth of Anhui province based on the 1991-2008 annual economic data by using some econometric analysis methods such as co-integration test,Granger causality test,impulse response function and variance decomposition and so on.The analysis shows;there is a two-way Granger causality between the science and technology input and the economic growth;the impulse response influence from the impulsion of the science and technology input to the economic growth is positive;the contribution rate of the science and technology input to the economic growth increases stably.
