Recently, the CPC Central Committee and the State Council issued the opinions on accelerating the construction of the national unified market (hereinafter referred to as the opinions), which put forward more clear principles, objectives and measures for accelerating the construction of the national unified market from the overall and strategic perspective. Building a national unified market reflects the internal requirements of promoting the common prosperity of all people and is of great significance to accelerating the process of common prosperity. The national unified market promotes common prosperity by establishing market rules of fair competition. The market can guarantee efficiency, but not fairness; The government can make up for market failure, but there is also the risk of offside and absence. Although China's socialist market economic system has long been established, problems such as industry monopoly, ownership discrimination and market access restrictions have not been completely eliminated, and the existence of these problems has an extremely adverse impact on creating a market environment of fair competition and realizing common prosperity in high-quality development. The opinions clearly put forward the need to improve the unified property right protection system, implement the unified market access system, maintain the unified fair competition system and improve the unified social credit system, and strengthen the unity of market basic system rules in the top-level design. This institutional arrangement is conducive to giving full play to the decisive role of the market in the allocation of resources and giving better play to the role of the government, allowing all kinds of market subjects to compete in a healthy market economy, enabling all kinds of production factors to obtain returns reflecting the value and contribution of factors, forming an initial distribution that reflects both efficiency and fairness, and providing a basic institutional guarantee for narrowing the income gap of residents. The national unified market promotes common prosperity by promoting the exchange and sharing of information platforms. Information is a scarce resource of modern market economy. Information asymmetry will not only lead to the failure of market allocation of resources, but also hinder the leap of economic development to a high level of supply-demand balance. In recent years, China has made great progress in promoting the deep integration of industrialization and informatization and the coordinated development of industrialization and digitization, which provides a powerful engine for high-quality development in the era of information and digital economy. On the other hand, there is a certain threshold for the access to information and data. Cities and developed areas are more likely to enjoy the benefits of informatization and digitization, while rural and underdeveloped areas are more likely to lose their development direction in the "digital divide", thus aggravating the imbalance of urban-rural and regional development. The opinions clearly put forward the need to build a modern circulation network, improve market information interaction channels, promote the optimization and upgrading of trading platforms, and promote the high standard connectivity of the market at the level of information infrastructure construction. This institutional arrangement can solve the problem of information asymmetry to the greatest extent by building an information resource sharing network integrating urban and rural areas and connecting regions, so that cities and villages, the East and the central and western regions can obtain equal development opportunities in the national unified information market. The national unified market promotes common prosperity by improving the efficiency of factor resource allocation. Building a national unified market of production factors is not only the key to improving the efficiency of resource allocation and promoting economic growth, but also an important guarantee to promote social equity and optimize the structure of income distribution. In recent years, China has made a series of major reform measures in promoting the efficiency of factor allocation, which has played a positive role in promoting the independent and orderly flow of factors. However, there is still a long way to go before the goal of truly realizing the market-oriented allocation of factors and making factors receive fair remuneration according to their actual contributions. In particular, the registered residence system and other institutional and institutional obstacles that hinder the free flow of labor factors, It has a very adverse impact on promoting the increase of labor remuneration in the proportion of national income. This opinion clearly proposes to establish and improve a unified market for labor, land, capital, technology, data, energy and ecological environment, and accelerate the construction of a market-oriented allocation system of factor resources. This institutional arrangement defines the reform direction of further removing the institutional and institutional obstacles that hinder the independent and orderly flow of factors. It is of great significance to improve the proportion of labor remuneration in the primary distribution, prevent the disorderly expansion of capital, promote the growth of rural residents' property income, and improve the basic socialist distribution system that is conducive to the realization of common prosperity. The national unified market promotes common prosperity by improving the supply capacity of goods and services. Common prosperity should not only focus on "common", but also on "prosperity". Improving the supply capacity of goods and services is the main way to promote high-quality development and constantly "make a big cake". In recent years, adhering to the main line of deepening supply side structural reform, China has made remarkable achievements in reducing ineffective and low-end supply and meeting the needs of consumption upgrading. On the other hand, the adaptability and flexibility of supply structure to demand changes are still insufficient. The "demand spillover" caused by insufficient effective supply has a negative effect on economic growth and dragged down the pace of realizing common prosperity. This opinion clearly proposes to improve the commodity quality system, improve the standard and measurement system, comprehensively improve the quality of consumer services, and realize the high-level unification of the commodity and service market on the basis of promoting the same line, standard and quality of domestic and foreign trade products. This institutional arrangement is conducive to the formation of policy guidance to encourage the supply of high-quality goods and services, and make China's economy develop in a direction that can better meet the people's growing needs for a better life. The national unified market promotes common prosperity by building a standardized and transparent business environment. A standardized and transparent business environment can inject vitality into the development of small, medium-sized and micro enterprises and contribute to innovation and development, entrepreneurship and prosperity. In recent years, China has made great progress in improving the business environment, enhancing the ability of market supervision, regulating unfair competition and market intervention. On the other hand, due to the influence of local and industrial protectionism, the behaviors that hinder market unity and fair competition instead exist in a more hidden form. The problems of low-level repeated construction, homogeneous competition, "small but complete" self small cycle and regional blockade are still common, which is not conducive to "making a big cake" or "sharing a good cake", and has become one of the most important risk sources for promoting common prosperity. This opinion clearly proposes to promote fair and unified market supervision, oppose monopoly and unfair competition, break local protectionism and regional industry entry barriers, and strive to improve the business environment. This institutional arrangement helps to give full play to the development potential of the super large-scale market, promote the formation of a positive incentive mechanism for the survival of the fittest, and provide an endogenous driving force for further stimulating the vitality of factors, encouraging entrepreneurship and innovation, and realizing common prosperity in high-quality development.
