The construction of a new development pattern with “domestic circulation as the main body, domestic and international circulation to promote each other” is an inevitable choice based on the new development stage, and the implementation of the new development concept, to promote highquality economic development. The “supplyside structural reform” is the main line running through the construction of the new development pattern, and the “demandside management” is in the strategic base position in the construction of the new development pattern. The key to building a new doublecycle development pattern is to integrate the “supplyside structural reform” and “demandside management”, to improve the quality of the supply system through “supplyside structural reform” to better match the “demandside management” in expanding domestic demand as a strategic base, to smooth the national economic cycle and to achieve a dynamic balance between supply and demand in the structure. With highquality development as the core essence of building a new development pattern of the double cycle, the focus of the policy is an to supplyside structural reform as the main line, from the source of innovation and selfreliance, quality and efficiency; based on demandside management, the expansion of domestic demand as a strategic base for economic development, and striving to open up the difficulties and blockages that hinder the release of domestic demand potential; from both supply and demand synergies to smooth the national economic cycle, to achieve a highquality balance of supply and demand.
