And further through the Granger causality test to measure the relationship between the change of capital stock and the effective growth of the real economy. The empirical results show that the elasticity coefficient of the capital stock in China is larger than that of the non-infrastructure capital stock, and the increase of the capital stock of the infrastructure is the Granger reason which leads to the effective growth of the real economy.
