Study on the coordination degree between fictitious and real economy in China based on grey correlation model

A coordinated development between fictitious economy and real economy would be beneficial to raise the quality of economic development. The coordination state of China´s fictitious economy and real economy has been analyzed in this paper by grey correlation model based on the annual data from 2002 to 2011, and the results show that “the turnover of treasury bonds”, “the turnover of futures”, “premium income” are the first three intimidated factors of the fictitious economy to the real economy. The coordination degree during 2002-2011 in China between fictitious economy and real economy shows significant fluctuations from 0.5320 to 0.7519, and the coordination state is relatively lower from 2007 to 2011 than it in 2002-2006, therefore, more attentions should be paid to grasp coordination mechanisms of the two systems correctly to promote sound and rapid development of China´s economy.
