From 2020 to 2022,China's macroeconomy was significantly impacted by exogenous shocks.The differences in output between contact-intensive and non-contact-intensive production sectors subtly revealed the asymmetric nature of the impact of exogenous shocks on different production sectors during this period.This paper defines sectoral structural shocks as exogenous fluctuations affecting only a portion of production sectors in the economy.The negative impact on China's macroeconomy during the mentioned period includes structural demand shocks to contact-intensive sectors.The effective use of macroeconomic policies to address these challenges is a matter of concern for academia and policy authorities.The paper establishes a dynamic stochastic general equilibrium(DSGE)model with heterogeneity in household and production sectors.We investigate how fiscal and monetary policies should be implemented and coordinated to effectively achieve the policy goals of"stabilizing employment and promoting consumption"under sectoral structural demand shocks.We identifies the negative sequences of structural demand shocks experienced by contact-intensive sectors during the mentioned period and subsequently utilize the model to analyze the effectiveness of different fiscal and monetary policy tools and coordination mechanisms.We find that the emphasis of different policy tools varies:government consumption and enterprise subsidy policies are more effective in stabilizing employment,while transfer payments to households and personal income tax rate policies are more effective in promoting consumption.Lowering policy rate can promote employment and consumption,while required reserve ratio is not an effective policy tool.The paper also examines the"monetary independence"and"non-monetary independence"fiscal-monetary policy coordination mechanisms.Results show that the"monetary independence"mechanism,where fiscal and monetary policy do not depend on each other,is more efficient in reducing real interest rates compared to the"non-monetary independence"mechanism,where monetary policy adjusts adaptively to fiscal policy.The research conclusions have at least two implications for the future design of fiscal and monetary policies.Firstly,the findings are applicable to general sectoral structural demand shocks,providing policy suggestions for future similar shocks.Secondly,the results subtly suggest that enhancing the independence of monetary policy can improve the effectiveness of the monetary-fiscal policy mix.Direct monetary accommodation to fiscal policy can subdue the effectiveness of policy mix.
