Legal basis: Article 3 of the 14th Five-year Plan for National Economic and Social Development of People's Republic of China (PRC) and the Outline of Long-term Goals in 2035 is strategically oriented. To promote high-quality development during the Tenth Five-Year Plan period, we must base ourselves on the new development stage, implement new development concepts and build a new development pattern. Grasping the new development stage is the realistic basis for implementing the new development concept and building a new development pattern. Implementing the new development concept provides an action guide for grasping the new stage of development and building a new pattern of development, which is a strategic choice to meet the opportunities and challenges in the new stage of development and implement the new development concept. We must persist in deepening the structural reform of the supply side, lead and create new demand with innovation-driven and high-quality supply, and enhance the resilience of the supply system and its ability to adapt to domestic demand. We should establish an effective system to expand domestic demand, accelerate the cultivation of a complete domestic demand system, strengthen demand-side management and build a strong domestic market. We must unswervingly push forward the reform, break down the institutional obstacles that restrict the economic cycle, and promote the circular flow of production factors and the organic connection between production, distribution, circulation and consumption. We must unswervingly open wider to the outside world, continue to deepen the flow of factors, steadily expand institutional opening, and rely on the domestic economic circulation system to form a powerful gravitational field of global factor resources. We must strengthen the leading role of domestic macro circulation, improve the efficiency and level of domestic macro circulation with international circulation, and realize the mutual promotion of domestic and international double circulation.
