The first article of the report of the 20th National Congress of the Communist Party of China in the chapter of "Accelerating the construction of a new development pattern and striving to promote high-quality development" proposed to build a high-level socialist market economic system, which shows the importance of building a high-level socialist market economic system to promote high-quality development. On November 9, Tao Yitao, the director and professor of China Special Economic Zone Research Center of Shenzhen University, made a keynote speech around "high-quality development and building a socialist market economic system" at the seminar of "In depth study of the spirit of the 20th CPC National Congress" launched by the Special Economic Zone Practice and Theory magazine of the Party School of Shenzhen Municipal Committee of the Communist Party of China. Tao Yitao believes that building a high-level socialist market economy system is the basis for promoting high-quality development. On the one hand, building a high-level socialist market economy system constitutes an important part of high-quality development; on the other hand, a high-level socialist market economy system is an indispensable institutional environment for high-quality development. The system is always embedded in the system environment. High quality development is the goal. The high-level socialist market economy system is both the goal content and the system environment to achieve the goal. The market economy is based on a highly developed commodity economy, and the resource allocation process of the whole society is based on the role of the market mechanism. The report of the Twentieth National Congress of the Communist Party of China emphasized that high-quality development is the primary task of building a socialist modern country in an all-round way. Without a solid material foundation, it is impossible to build a socialist modern power in an all-round way. Therefore, we should adhere to the direction of socialist market economy reform, adhere to a high level of opening up, and strengthen the construction of a new development pattern with the domestic big cycle as the main body and the domestic and international double cycles promoting each other. Tao Yitao believes that these discussions are a highly summarized and profound reflection on the reasons for China's great achievements over the past 40 years of reform and opening up. Without the improvement of the market economy system and economic development, there can be no material basis for wealth creation and the realization of a modern power. Without a high-level vision of opening up and internationalization, there can be no institutional guarantee for the realization of a dual cycle development pattern. Similarly, there can be no technological progress and invention without an institutional and cultural environment that encourages innovation. Tao Yitao pointed out that the report of the 20th National Congress of the Communist Party of China emphasized that giving full play to the decisive role of the market in resource allocation and giving better play to the role of the government is a feature of the socialist market economic system with Chinese characteristics. To give full play to the decisive role of the market in resource allocation is to follow the market rules as the basic principle of the socialist economic system with Chinese characteristics. Therefore, while emphasizing the promotion of state-owned capital and state-owned enterprises to become bigger and stronger, the report also emphasizes the optimization of the development environment for private enterprises, the protection of private enterprise property rights and entrepreneurs' rights according to law, and the promotion of the development and growth of private enterprises. Tao Yitao said that building a new development pattern includes both high-quality development and high-level openness. If the new development pattern is the strategic deployment of the new era, high-quality development is the core content of this strategic deployment, and high-level openness is an important practical path of this strategic deployment. Tao Yitao believes that the construction of the new development pattern stems from the rapid development of China's social economy and the fundamental improvement of China's national strength over the past 40 years of reform and opening up, and stems from the four
