The “Five Must-Be-Coordinated Aspects” are important contents in Volume I of Selected Works of Xi Jinping on Economy, representing the latest development of Xi Jinping’ s economic thought. The “ Five Must-Be-Coordinated Aspects” are important strategic deployments made by the CPC Central Committee with Comrade Xi Jinping at its core at critical moments and junctures for China’s economic development. Each part covers cutting-edge issues in current economic work, and all parts are closely interrelated. The proposal of the “Five Must-Be-Coordinated Aspects” has a profound background. The “Five Must-Be-Coordinated Aspects” are inevitable requirements for continuously promoting high-quality development, maintaining a relatively high economic growth rate, comprehensively building a modern socialist country, responding to changes in the international economic and political environment, and steadily advancing the new development pattern. The “ Five Must-Be-Coordinated Aspects” have profound inherent characteristics. They reflect that the feature of multi-objective coordination in China’s economic construction has become increasingly prominent in the high-quality development stage. In the process of China’s transformation from a catching-up economy to a developed one, it is necessary to balance multiple aspects of relationships. Currently, the reform needs to address both long-term and short-term issues, as well as superficial and deep-seated contradictions. The key tasks of the “Five MustBe-Coordinated Aspects” include establishing an economic order that is “flexible” yet “manageable”, building a coordinated and dynamically balanced relationship between aggregate demand and aggregate supply, and handling the relationships between the “new” and the “old”, and between “quality” and “quantity”.
