文摘In different economic periods,if the government blindly adopts expansionary fiscal policy,it may not be able to effectively increase total factor productivity(TFP).Based on this,this paper constructs a factor augmented vector autoregressive model with time-varying parameters and stochastic volatility(SV-TVP-FAVAR),and explores the nonlinear shock effect of China’s fiscal policy on TFP from the dual perspective of aggregate and structure.The study finds that:(1)At the aggregate level,the increase in fiscal expenditure in each period has a signifi cant inhibitory effect on TFP,while the increase in fiscal revenue has a significant promotion effect on TFP;(2)At the structural level of expenditure,in the period of economic depression and high economic growth,the increase in investment expenditure,education expenditure,technology expenditure,and public service expenditure all have a strong incentive effect on TFP,but the increase in science and technology and education expenditure in the period of economic stability has not effectively improved TFP;(3)At the structural level of tax,the increase in commodity tax,including consumption tax,value-added tax,and tariff,and individual income tax will signifi cantly inhibit the increase in TFP,but the increase in corporate income tax can signifi cantly increase TFP.Therefore,under the new economic normal,policy makers should build a two-wheel driven fiscal policy of“aggregate regulation and structural optimization”to optimize the structure of fiscal expenditure and taxation,and promote high-quality economic development.
