基于C-D函数的高新技术产业科技投入产出效率分析

Analysis of science and technology input and output efficient of high technology industry based on C-D function

研究采用Eviews 6.0计量经济学软件,根据中国高新技术产业1999年-2012年相关数据,采用滞后变量模型和回归分析的方法,对高新技术产业科技投入与产出之间关系进行了实证分析,并得出结论。从总体上看,科技投入在短期内极大地促进了高新技术产业的发展;从长期来看,科技投入的短促性非常明显,当滞后期为4年或4年以上时,科技投入这一生产要素已不具有显著性。

By using econometrics software Eviews 6.0,according to the related data of China＇s high technology industry from1999 to 2012,empirical analysis about the relationship between science and technology input and output of high technology industry is implemented with lag variable model and regression analysis method.Overall,in the short term,investment in science and technology greatly promotes the development of high technology industries;in the long run,the briefness of investment in science and technology is very obvious：when the lag period is 4years or more,investment in science and technology has no significance.
