On Grey Incidence Model Application about Chinese Economic Growth and Science Technology Input

Grey system model can solve many problems with insufficient information and samples. Taking Chinese economic growth and its science input for example, the grey incidence analytic system is constructed to explore their correlation relationships. Combining the computing results and the actual situation of science technology input and Chinese economic growth, grey incidence model proves to be significant applicability, robustness and effectiveness. And the results also indicate that the correlation relationship of science technology expenditure to GDP is closer than that of scientific researcher to GDP. It is necessary to increase science technology expenditure to speed up the development of Chinese scientific groups then to promote the growth of Chinese economy.
