With regard to building a high-level socialist market economy, the Decision of the Central Committee of the Communist Party of China on Further Comprehensively Deepening Reform and Promoting Chinese path to modernization clearly states that "it is both 'flexible' and 'manageable'". At present, China's development has entered a period of strategic opportunities and risks, and promoting high-quality development still faces the problem of unbalanced and insufficient development. We must firmly grasp the bull's nose of liberating and developing productive forces, organically unify the "invisible hand" of the market with the "tangible hand" of the government, and achieve mutual complementarity, coordination, and promotion between the two in a high-level socialist market economy system. Give full play to the decisive role of the market in resource allocation, and better stimulate the endogenous driving force and innovation vitality of the whole society. Market allocation of resources is the most efficient form, and market economy is essentially an economy where the market determines the allocation of resources. The series of important deployments in the Decision sends a strong signal - to better leverage the role of market mechanisms, create a more fair and dynamic market environment, and achieve optimal resource allocation efficiency and maximum benefits. Fully leveraging the government's initiative in macroeconomic regulation can better maintain market order and overcome market failures. Scientific macroeconomic regulation and effective government governance are inherent requirements for leveraging the advantages of the socialist market economy system. The Decision makes arrangements for improving the macroeconomic governance system, proposes to enhance the national strategic planning system and policy coordination mechanism, and highlights the important role of the government in promoting high-quality economic development. By combining both "letting go" and "managing", we will persist in using both hands to promote the organic integration of the market and the government. The market will be more effective and the government will be more proactive. The Chinese economy will surely be able to sail through the wind and waves, move steadily and achieve long-term success.
