Co-integration Test of Information Industry and Economic Growth in China

According to the co-integration theory and China's annual data of 1991-2011,the paper makes a co-integration test and Granger causality test on the relationship between China information industry and economic growth,and establishes a corresponding error correction model.The results show that there is a long-term stable equilibrium relationship between information industry and economic growth in China.However the equilibrium relationship is of the low capability for self-correction of the current non-equilibrium error.The information industry development is the Granger cause of the economic growth,but the economic growth does not constitute the Granger cause of the information industry development.
