Coordination State of China´s Fictitious Economy and Real Economy

China´s fictitious economy has been developing rapidly since 1990. Rapid expansion of scale of fictitious economy can make positive or negative impacts on real economy, so it needs to prevent over-development of fictitious economy taking negative influences to real economy. The coordination state of China´s fictitious economy and real economy has been analyzed by grey correlation model based on the yearly data from 1998 to 2009, and the results show that the correlation degrees of the representative variables the total loans and the money and quasi-money with GDP are higher, the correlation degrees of the turnover of stock trading, the turnover of treasury bonds, the turnover of foreign exchange, and the turnover of commodity futures trading with GDP are lower, and the degree of the turnover of trading of investment of futures and securities with GDP is lowest. Therefore, it needs to promote coordinated development between China´s fictitious economy and real economy.
