Based on the statistical data of science ＆ technology finance and economic development of China from（ 1992 to 2011 ）, using the unit root test, co-integration test and Granger causality test theory and others, this paper empirically analyzes the relationship between science ＆ technology financial investment and economic development, which indicates that there is obvious two-way causal rela- tionship between the science ＆ technology financial investment and the economic growth in China. The increase in science ＆ technolo- gy investment improves economic growth in China, meanwhile economic development also advances more investment of science ＆ tech- nology finance. According to the results, the government should put more emphasis on the science and technology financial support and coordination to improve the science ＆ technology financial investment in promoting economic growth.
