Abstract: Revealing the variation of effect of government consumption scale on economic growth was an important basis for reasonable regulating of government consumption scale and allocating of government public resourcesBy using the 1978—2011 data,and using threshold cointegration model for empirical research on the relationship between government consumption scale and economic growth,this paper found there existed threshold cointegration relation between government consumption scale and economic growth,and the effect of government consumption scale on the economic growth was always negativeWhen the proportion of the government consumption account for GDP declined to 01782 previously in the period of 1978—1986,the promotion effect of government consumption scale on economic growth was smallerWhen the proportion of the government consumption account for GDP fell to 01782 around 1987,the effect of government consumption scale on economic growth took place nonlinear transferWith further reducing government consumption scale,the promoting effect of government consumption scale on economic growth was significantly strengthened from 1996—2011The empirical results showed continuously compressing the government consumption scale would improve economic efficiency,especially when the government consumption scale being controlled below critical value 01782,the role of government consumption promoting economic growth would get stronger
