本文以浙江省为例子,选取外商直接投资(FDI)和国内生产总值(GDP)数据,利用CD生产函数和索罗方程建立模型,并利用Eviews软件进行变量的平稳性检验看变量是否为平稳序列,再根据变量的协整关系检验。最后利用最小二乘法判断GDP与FDI直接是否存在协整关系,并利用Granger因果检验进一步验证上面协整检验的结果是否存在因果关系。最后得出结论,FDI对浙江省经济发展起促进作用。
Taking Zhejiang Province as an example, this paper chooses FDI and GDP data, uses the CD production function and Solow equation to establish a model, and uses the Eviews software to test the stationarity of the variables to see whether the variables are stable Sequence, and then test the cointegration relationship according to variables. Finally, the least square method is used to judge whether cointegration relationship exists directly between GDP and FDI, and the Granger causality test is used to further verify whether there is a causal relationship between the results of the cointegration test and the above. Finally, it is concluded that FDI promotes the economic development of Zhejiang Province.
