To achieve the long-term goal of basically realizing socialist modernization by 2035,it is necessary to maintain a relatively high economic growth rate in the coming decades.China's poten-tial growth rate has declined rapidly in recent years.There is an urgent need to raise the potential growth rate to a higher level.The existing western macroeconomic policy theory focuses on how to utilize the short-term stabilization policies to maintain aggregate demand close to the potential growth rate.Yet this sort of theory cannot explain the rapid decline in potential economic growth,nor can it provide a feasible solution to raise the potential growth rate.To enhance the consistency of macro policy orientation is an important part of efficient macroeconomic governance.It provides a new approach to increase China's potential economic growth rate.The Macro-Policy Trinity Theory provides a theoretical foundation for the consistency of macro policy orientation to reveal the under-lying logic of macroeconomic policy regulation.The essence of the Macro-Policy Trinity Theory is to integrate structural policies,growth policies,and stabilization policies to provide a logical sequence of and the path to their implementation.By unifying these three types of policies,China can enhance the consistency of macro policy orientation,effectively increase the potential economic growth,and advance the Chinese modernization.
