Under the intermittent recurrence of the epidemic, the uncertainty of economic risks has increased, and the economic cycle has been impacted. Unpredictable pro‐economic cycle policies will inevitably exacerbate macroeconomic instability. The 2021 government work report proposes counter‐economic cycle and cross‐economic cycle strategies, based on medium and long‐term macro policy formulation. Due to the fact that Chinese residents are less sensitive to interest rates, the role of spontaneous economic adjustment is relatively small, and policies need to be adjusted macroscopically through the central bank's monetary policy and credit policy. This paper first separates the cyclical factors and trend factors of the industrial added value from 2016 to 2022, and finds that under the impact of the epidemic in 2019, the economic cycle phase suddenly turned into a decline, and gradually changed to recovery after regulation. At the same time, based on the former's improved China Merrill Lynch clock theory, consider the macro policy, inflation level, financial environment, and internal and external balance factors to explain the fluctuation trend, analyze the current effect of my country's macro policy, and reduce sudden external shock fluctuations for the optimization of macro control. Put forward reasonable suggestions on risk‐resisting policies.
