The Fourth Plenary Session of the 20th CPC Central Committee mapped out a grand blueprint for China's development in the next five years, profoundly pointed out that a strong domestic market is the strategic basis for Chinese path to modernization, and proposed the strategic task of "building a strong domestic market and accelerating the construction of a new development pattern". During the "Tenth Five Year Plan" period, we need to work together at both ends of supply and demand to boost consumption, expand effective investment with the focus on optimizing structure and improving quality, break through and simultaneously promote the construction of a unified national market, and provide a strong guarantee for promoting high-quality development and promoting Chinese path to modernization. 1、 In December 2018, General Secretary Xi Jinping first proposed the concept of "strong domestic market" at a meeting of the Political Bureau of the Communist Party of China Central Committee, clearly stating the need to "promote the formation of a strong domestic market and enhance the overall level of the national economy". Since then, General Secretary Xi Jinping has repeatedly emphasized the need to build a strong domestic market on various occasions. The so-called strong domestic market refers to a domestic market with a large scale, matching supply and demand, active innovation, perfect software and hardware environment, significant role in driving economic development, and significant attractiveness and influence globally. The foundation of a strong domestic market lies in its size, and the key lies in its strength. Its characteristics mainly include the following five aspects. Firstly, the market has a large scale and strong growth potential, with strong consumer and investment demand, playing an important role in driving economic growth, expanding employment, and improving people's livelihoods; Secondly, the segmented market has matured, with sufficient supply and high adaptability and flexibility to changes in demand; Thirdly, the popularization of emerging cutting-edge technologies, diverse application scenarios, and the full release of the value of data elements provide impetus for market innovation and development; Fourthly, the market infrastructure is sound, with a fair, transparent, and predictable investment environment and a safe, convenient, and reassuring consumption environment. The market is open to each other, with unified rules and a high level of modern supervision; Fifth, it is connected to the global market and has outstanding absorption capacity for external goods, services, funds, technology, etc. The construction of a strong domestic market during the 15th Five Year Plan period is both in line with and keeping pace with the 14th Five Year Plan period. The 14th Five Year Plan period officially launched a new journey of comprehensively building a socialist modernized country. The period of the 15th Five Year Plan is a crucial period for consolidating the foundation and making comprehensive efforts to achieve socialist modernization. In the "Proposal of the Central Committee of the Communist Party of China on Formulating the 15th Five Year Plan for National Economic and Social Development" (hereinafter referred to as the "Proposal") adopted at the Fourth Plenary Session of the 20th Central Committee of the Communist Party of China, it is specifically listed as "building a strong domestic market, accelerating the construction of a new development pattern", and deployment is made to vigorously boost consumption, expand effective investment, and resolutely eliminate obstacles to the construction of a unified national market. These three major measures not only maintain continuity with the 14th Five Year Plan period, but also accurately grasp the new requirements for development in the next five years, which is a step-by-step and continuous process of development and progress. 2、 Fully understanding the importance of building a strong domestic market and achieving high-quality development is one of the essential requirements of Chinese path to modernization, as well as the theme of economic and social development during the "15th Five Year Plan" period. Building a strong domestic market is of great significance in many aspects for promoting high-quality development and promoting Chinese path to modernization. Strengthen the strong support of the domestic circulation. The only way to promote Chinese path to modernization is to accelerate the construction of a new development pattern with domestic circulation as the main body and domestic and international double circulation promoting each other. The unique advantage of a large country's economy lies in its dominance of domestic demand and internal recyclability. Currently, China's domestic wealth creativity and purchasing power have significantly increased compared to the past, and the reliability and stability of the domestic demand market exceed that of the external demand market. During the 15th Five Year Plan period, China's economic development accelerated its transformation, but faced a more complex and volatile external environment, with intertwined world turmoil and intensified turbulence, unilateralism and protectionism rising, hegemonism and power politics threats increasing, and the world economy lacking growth momentum. Against the backdrop of increasing uncertainty in external demand, fully unleashing the potential of domestic demand has become the key to firmly grasping the initiative in development. Only by building a strong domestic market, adhering to the strategic basis of expanding domestic demand, and taking meeting domestic demand as the starting point and foothold of development, can production, distribution, circulation, and consumption rely more on the domestic market, lead new supply with new demand, create new demand with new supply, promote the benign interaction between consumption and investment, supply and demand, enhance the endogenous driving force and reliability of the domestic circulation, promote the formation of more domestic demand led, consumption driven, and endogenous growth economic development models, and boost market expectations and confidence. The objective requirement for developing new quality productive forces. Chinese path to modernization should be supported by the modernization of science and technology, and the development of new quality productivity is the internal requirement and important focus of high-quality development. During the 15th Five Year Plan period, a new round of technological revolution and industrial transformation will accelerate breakthroughs, and technological innovation will present a trend of multi technology cross integration and collective leap. The disruptive, penetrative, and diffusive characteristics will become more prominent, profoundly reshaping the industrial form and economic pattern. More new economic activities will be formed around the application of new technological achievements. Building a strong domestic market, especially deepening the construction of a unified national market, unifying market basic systems, market infrastructure, government behavior standards, market supervision and law enforcement, and factor resource markets, continuously expanding domestic and foreign opening up, is conducive to better leveraging the unique advantages of super large markets in providing rich application scenarios, amplifying innovation benefits, stimulating innovation, sharing costs, reducing risks, guiding the rational allocation of innovation resources through market demand, and providing greater development space for innovation. In this process, the deep development of segmented markets will also provide more value exploration space for innovation, promote the improvement of the innovation ecosystem, continuously generate new quality productivity, and enhance the endogenous driving force of economic development. The practical need to improve the quality of people's lives. Realizing people's yearning for a better life is the starting point and end result of Chinese path to modernization. Consumption, as the ultimate demand, is a direct reflection of people's need for a better life. During the 15th Five Year Plan period, people's longing for a better life will become stronger, and the trend of diversified, personalized, and quality-oriented consumption will become increasingly evident. Service consumption will continue to grow. According to data from the National Bureau of Statistics, in 2024, the per capita service consumption expenditure of residents accounted for 46.1% of the per capita consumption expenditure of residents. It is expected that during the 15th Five Year Plan period, this proportion will exceed 50%, achieving a structural transformation from commodity consumption dominance to service consumption dominance. Building a strong domestic market, focusing on solving the problem of imbalanced and insufficient market development, fully exerting market power, expanding the supply of middle and high-end products, is conducive to better meeting the people's practical needs for higher quality goods, better education, more comfortable living conditions, higher-level medical and health services, and richer spiritual and cultural life, enhancing their sense of achievement and happiness, and promoting comprehensive human development. A powerful guarantee for shaping the external environment. Chinese path to modernization is a modernization that follows the path of peaceful development. In today's world, the most scarce resource is the market. In 2024, China's total economic output will reach a new level, ranking second in the world in terms of economic scale, and becoming the world's second largest consumer market and import market for several consecutive years. During the 15th Five Year Plan period, the size of China's middle-income group will further expand, consumer demand will continue to be released, and the combination of consumption and emerging technologies will drive rapid growth in new consumption. As the world's most promising consumer market, China will continue to grow and expand. Building a strong domestic market, actively expanding independent opening up, attracting and utilizing foreign investment more vigorously and effectively, ensuring national treatment for foreign-funded enterprises, is conducive to shaping a favorable external environment for China, smoothing the domestic and international dual circulation, closely connecting with the world economy, cultivating new advantages in international cooperation and competition, providing more opportunities for countries to share the Chinese market, and injecting more stability and certainty into the development of the world economy. 3、 Comprehensively implementing major measures to build a strong domestic market, both supply and demand sides are working together to boost consumption. During the 15th Five Year Plan period, China accelerated the construction of a domestic demand pattern dominated by household consumption. The "Proposal" specifically regards "a significant increase in household consumption rate" as one of the main goals for economic and social development in the next five years, and proposes to implement in-depth special actions to boost consumption. To this end, we must focus on enhancing residents' consumption ability and willingness. Strengthen macroeconomic regulation and prioritize employment, promote reasonable growth of wage income. Further stabilize employment positions, improve employment structure, expand employment capacity in the service industry, leverage the role of private enterprises as the main force in absorbing employment, and improve the employment support system for key groups such as college graduates and migrant workers. Improve the incentive and restraint mechanism for dividends of listed companies, enrich fund products such as bond funds and money market funds, and further expand the channels for property income. Establish a sound social security system and steadily promote equalization of basic public services. Strengthen support for childbirth and nurturing, and reduce residents' worries about consumption. Intensify inclusive policies that directly reach consumers and increase government funding for livelihood security expenditures. Secondly, we need to expand the supply of diversified high-quality consumer goods and services. Strengthen brand leadership, standard upgrading and new technology application, encourage enterprises to integrate China-Chic elements in product design, fashion experience and other aspects, and promote consumption expansion and upgrading of automobiles, household appliances and electronic products. Focusing on relaxing access and integrating business formats, we will expand service consumption, clean up unreasonable restrictive measures in fields such as culture, sports, healthcare, and education, and vigorously develop consumption formats that integrate business travel, culture, sports, sports, and health. Cultivate international consumption center cities, better leverage duty-free shops and exit tax refund policies, and expand inbound consumption. Thirdly, we need to increase new consumption scenarios and leisure time. Considering the characteristics of service consumption such as tourism, cultural, sports and entertainment, which involve synchronous production and consumption, direct interaction, and are constrained by leisure time, it is necessary to support innovative and diversified service consumption scenarios, create clusters of first-time economy and nighttime economy, implement paid off peak vacation, and make the implementation of paid vacation system an important part of labor supervision and employee rights protection. Expand effective investment with a focus on optimizing structure and improving quality. During the 15th Five Year Plan period, there are still many shortcomings and weaknesses in China's industrial transformation, new urbanization construction, and improvement of social livelihood, and there is still room for expanding effective investment. To this end, it is necessary to further clarify the investment direction and priorities of the central and local governments. Focus on areas with strong strategic and external factors that private capital is unwilling to invest in, carry out public investment, coordinate and make good use of various government investments, manage and make good use of central budget investments, optimize special bond projects and fund management mechanisms, strengthen the management of the entire process of government investment, and deepen the reform of the investment approval system. Secondly, we need to optimize the structure of government investment. Promote high-quality "dual" construction and increase the proportion of government investment in people's livelihood. Adapt to changes in population structure and mobility trends, improve the layout of infrastructure and public service facilities, accelerate the narrowing of basic public service gaps between regions, urban and rural areas, and groups, and increase public investment in education, healthcare, elderly care, and other fields. Establish a sound long-term mechanism for investing in people, optimize fiscal expenditure responsibilities and financial allocation. Pay more attention to revitalizing the stock of idle and inefficient assets and other resource factors, improve the utilization efficiency of various types of stock assets, and use stock revitalization to drive incremental optimization. Thirdly, we must stimulate the vitality of private investment. Relaxing restrictions on private investment access, breaking down implicit barriers, improving long-term mechanisms for private enterprises to participate in major project construction, and enhancing effective investment growth driven by the market. Strengthen the coordination of investment and financing policies, and improve
