Abstract: Based on endogenous classification method in fiscal adjustment period，this paper used smooth transition regression models to study implementation mechanisms and dynamic characteristics of fiscal policy in 1980—2012It came to the following conclusions：Firstly，the nonlinear effect of fiscal policy changed through consumption channel and influenced the consumer expectationsSecondly，the combinations of noKeynesian effect of fiscal policy under different conditions and the fiscal policy tools were certain differencesWhen the primary budget surplus/GDP was less than the critical value of -0045 0，fiscal revenue had nonKeynesian effects on consumer demandOn the contrary，when the primary budget surplus/GDP was greater than the critical value of -0045 0，fiscal expenditure on consumer demand had nonKeynesian effects to some extentIn addition，the governments initial sizes of the debt and the magnitude of the fiscal adjustments were not important factors to the nonlinear effects of fiscal policy in our countryThis paper provided the theoretical basis and decision reference for the government，and improved operational efficiency and operational effectiveness of fiscal policy in China
