国民经济和科技投入水平之间的结构关系分析——基于省级面板数据的Granger因果检验

An Analysis of the Structural Relationship between the National Economy and the Investment Level of Science and Technology——Granger Causality Test Based on Provincial Panel Data

首先通过熵值法计算科技投入水平的评价值,并与国民经济进行协整检验和Granger因果检验,进一步分析科技投入水平与国民经济之间均衡关系;随后引入Cobb-Douglas方程建立回归模型,并用最小二乘法估计回归模型的参数。结果表明,科技投入水平与国民经济之间存在均衡关系,并且国民经济增长是科技投入水平提高的Granger原因,说明国民经济增长对科技投入水平具有显著的单向促进作用。

We firstly calculate the value of technology investment level by entropy method.And then compared with the national economy,we further make the co-integration test and Granger causality test,and analyze the equilibrium relationship between the national economy and technology investment level.Then we introduce the Cobb-Douglas equation to establish regression model,and use the least squares to estimate the parameters of regression model.Results show that,there is the equilibrium relationship between investment in technology level and the national economy,and the growth of national economy is a Granger cause of investment in science and technology level,on the other hand,the growth of national economy has a significant role in one direction for the investment of science and technology level.
