This paper applies cointegration theory and Granger causality test to study the correlation between human capital and economic growth in rural area in order to test the trap of rural human capital existed or not.

Based the review of existing theories of money supply, the paper adopts the cointegrate test, Granger causality and impulse response test to analyze the endogenesis of money supply in China.

The Granger causality test shows that there is only single-direction causality between export or im.

Vector Granger causality and its application in complex network;

Frequency domain Granger causality and its application in signal processing;

Nonlinear Granger causality and its application in computational neuroscience;

By employing the co-integration test and the Granger-causality test,the authors make an authentic analysis of the relationship between economic growth and employment of Inner Mongolia,the result of which indicates that there existed a stable co-integration relationship between economic growth and employment of Inner Mongolia during the y.

The paper uses the Granger-causality test to analyze the two-way causality between logistics development and economic growth in Zhejiang Province,and finds out that they are the cause for each other,namely there are interaction relationship between logistics development and economic growth at the present in Zhejiang Province.

Based on the collection of the annual housing price in Nanjing and real effective exchange rate(REER) of RMB from 1997 to 2008,this paper establishes the error correction model and carries out the Granger-causality test on the relation between the RMB exchange rate and housing price.

Discussion on How to Do Granger Causality Test;

This paper, based on Granger causality test in a vector autoregressive process, empirically analyzed the money supply in China.

Then Granger Causality Test was made to prove that increase rate of overmuch currency is the cause of CPI and CPI, on the other hand, cannot act as the cause of increase of increase rate of overmuch currency in China, thus indicating that central bank control of the development of economy by adjusting currency supply remains to be of practical significance.
