Abstract
This paper uses econometric model to analyze the influence of information industry on economic growth and their causality.Based on the historical data,it tests the time series variables through regression analysis,vector autoregressive model analysis and Granger causality tests.The results indicate positive correlation between information industry and economic growth,and the two time series variables are co-integration.In the lag time of 2,3 and 4,information industry is Granger cause of economic growth.In the long run,information industry and economic growth shows significant positive correlation.
