工程建设标准对我国经济增长影响的实证研究——基于协整理论、Granger因果检验和岭回归

首先运用协整理论和Granger因果检验分析了工程建设标准和经济增长的关系;接着引入Cobb-Douglas生产函数建立回归模型,并用岭回归估计,修正了最小二乘回归中系数易受多重共线性影响的缺点;最后运用虚拟变量法对回归方程的结构稳定性进行了检验。研究结果表明:工程建设标准和经济增长之间存在长期均衡关系,且前者是后者的Granger原因,反之不成立;工程建设标准对经济增长具有显著的促进作用,且在1993年以后,其作用显著增大.

Effect of Chinese engineering construction standards on economic growth:Empirical research based on cointegration test,Granger casualty test and ridge regression

In this paper,firstly,we used cointegration test and Granger casualty test examining the relationship between Chinese engineering construction standards and economic growth.Then,based on the Cobb-Douglas production function,we built a regression model studying Chinese engineering construction standards' effect on economic growth,and also applied ridge regression to avoid the colincarity effect. Finally,we tested the stability of the production function by applying the dummy-variable method.The empirical res...
