Abstract Investment is one of the key factors that influence the economic growth. Based on the data of the fixed investments from 1981-2012, the author conducts an ADF test, a co-integration analysis and a Granger test of causality upon the data with the help of Eviews 6.0. The results show that there exists a co-integration relationship between the investments and economic growth, and the former has remarkable impact on the latter. Our study also reveals that the investment fluctuation shares the same frequency of occurrence with the economic fluctuation, and a similar wave length. In relative terms, the amplitude of the investment fluctuation is significantly greater than the economic fluctuation; in other words, economic growth is lagging behind investments.
