Unobstructed channels for the social mobility of the labor force and talents constitute an important support for the sustainable and healthy development of the, a significant indicator of a vibrant and dynamic society, and a necessary requirement for achieving the all-round development of individuals and common prosperity. General Secretary Xi Jinping pointed out:Eliminate the institutional and policy shortcomings that hinder the mobility of labor force and talents" "and enable everyone to have the opportunity to achieve their own development through diligent work. The Fourth Plenary Session of the 20th Central Committee of the Communist Party of China proposed in its "Recommendations": "Unblock social mobility channels and improve peoples quality of life." At present, our country is at a critical period of comprehensively building a socialist modernized country, and creating mobility opportunities, unblocking mobility channels and expanding mobility space for the labor force and talents are of great significance for optimizing the allocation of human resources, promoting social fairness and justice, and consolidating the talent foundation for-style modernization. We must deeply understand General Secretary Xi Jinping's important exposition on talent work, thoroughly implement the spirit of the Fourth Plenary Session of the 0th Central Committee of the Communist Party of China, eliminate the institutional and mechanism shortcomings that hinder the social mobility of the labor force and talents, speed up the unblocking of social mobility channels for the labor force and talents, and let the labor force and all kinds of talents burst into action and gather the magnificent power of hundreds of millions of people to move common prosperity and achieve national rejuvenation.

It is of strategic importance to unblock the channels of social mobility of labor and talent. From the perspective of promoting high-quality economic development, China's overall layout of labor and talent is still unbalanced, and the mobility of labor and talent is still constrained by various factors. Unblocking social mobility channels to improve the matching efficiency of human capital and physical capital, break down the barriers to factors among regions and industries, and achieve dynamic equilibrium of factors of production and sustained improvement of total productivity. From the perspective of speeding up the realization of common prosperity, promoting the social mobility of labor and talent helps workers to increase their income through various means such as skills upgrading, conversion and entrepreneurship and innovation. From the perspective of maintaining social fairness and justice, the ultimate goal of Chinese-style modernization is to realize the free and all-round of human beings. According to the results of the Seventh National Population Census, the proportion of migrant population in the total population of the country has exceeded 1/4. Uning the channels of social mobility helps to gradually break the unreasonable restrictions of household registration and identity, and enable everyone to have the opportunity to achieve their own development through diligent work, that the achievements of modernization can benefit all the people more and more fairly. To this end, we must actively explore effective paths to unblock the channels of social mobility of labor talent, do a good job in top-level design, encourage all parts of the country to adjust measures to local conditions and actively innovate, promote the reform of the social mobility and mechanism of labor and talent, remove the obstacles to horizontal and vertical mobility, and build a reasonable, just, unblocked and orderly pattern of social mobility.

Enhance strategic overall coordination and build a collaborative and efficient system for talent work. Talent work is a strategic task and systematic that needs to be planned and promoted with strategic thinking. Insist on the systematic concept, strengthen overall coordination and coordination, balance the relationship from the overall perspective, and form a highefficiency collaborative force for talent work. Insist on the principle of the Party governing talents, improve the mechanism of overall coordination by region, and avoid excessive loss of high-level talents the central and western regions and the northeast region. Deepen the reform of talent working mechanism, improve the mechanism of training, introducing, utilizing, and rational flow of talents. Improve unified and standardized human resources market system and improve the market-oriented level of human resources flow. Encourage all regions to take actual development needs as the guide, insist on the full chain of "attraction, cultivation, retention, and utilization", improve relevant policies, and avoid fragmented and short-term behaviors.
Optimize the institutional environment and the channels of horizontal mobility. As a powerful constraint and incentive mechanism, the system has the most universal and direct impact on individuals' horizontal mobility between different spaces, industries, and units Only by systematically clearing away the institutional obstacles that hinder horizontal mobility can we fundamentally guarantee the right of labor force and talents to migrate freely to realize personal values. We need to deepen reform of the household registration system, unblock the channels of mobility between urban and rural areas and regions; break the industry monopoly and employment discrimination, strictly prohibit the setting of discrimin and restrictive clauses, and create a fair employment environment; support public institutions to introduce urgently needed high-level professional and technical talents through special posts, and support and encourage public institution researchers to work part-time and leave their posts to establish enterprises according to regulations. Use big data, cloud computing and other digital technologies, build a unified and open, online and integrated public employment service platform, and improve the efficiency of labor market allocation.
Improve career development channels and expand the space for vertical mobility and upward social mobility. Vertical mobility refers to the leap of individuals or groups terms of income grouping, skill level, and social status, which is related to the release of the development potential of social members. Only by building a ladder for vertical development, forming diversified, open, and smooth upward channel, can we stimulate the vitality of the whole society to innovate, start businesses, and create. It is necessary to improve the and market-oriented level of talent evaluation, improve the job promotion and salary distribution mechanism oriented by ability and performance, and improve the system for the use and incentive of skilled talent Strengthen industry-academia-research integration dominated by enterprises, support enterprises to take the lead in establishing innovative alliances, and form a cultural atmosphere that respects innovation andates failure. Promote educational equity and quality improvement, build an integrated vocational and general education system and an integrated industry-education system, and build a lifelong learning system serving the people. For example, the three projects of "Yue Cuisine Master", "Guangdong Skilled Workers", and "Nan Yue Home Service" inzhen, Guangdong Province, combine vocational skills training with rural revitalization, industrial upgrading, and counterpart assistance, which broadens the employment channels and income growth space of in the market and effectively promotes the vertical mobility of labor force.

Strengthen the security system and weave a tight safety network. The floating workforce and talents confront uncertain factors such as unstable and fluctuating incomes in the process of mobility. Whether the basic security is sufficient and the rights expectation is stable is closely related to the choice of mobility. Only by strengthening the construction social security, weaving a tight and fine "safety net" for the mobility of fairness and stability, can we really reduce the worries of the mobile population. We should steadily promote construction of the social security system with Chinese characteristics, improve the multi-level social security system covering the whole people, coordinating urban and rural areas, being fair and unified, safe and, and sustainable. We should improve the overall planning level of various types of social insurance, ensure their safe and effective operation. We should strengthen labor supervision and judicial assistance, strengthen construction of the legal service team, and legally guarantee the legitimate rights and interests of workers. For instance, Chongqing has optimized the service for the transfer and continuation of social relations, promoted the reform of the mechanism of "cross-provincial fast transfer" of old-age insurance relations in depth, experimented with the regular settlement of funds for transfer of old-age insurance relations first, greatly compressed the average processing time for the transfer of old-age insurance relations, cancelled a number of paper application materials through data sharing and process, significantly reduced the burden of personnel on mobility across provinces, strengthened the convenience of social security, and created convenient conditions for the mobility of labor force and talents.
Adhere to the principle of suiting measures to local conditions, and encourage grass-roots exploration. The mobility of labor and talents is greatly affected by environmental conditions. There are differences industrial structure, population scale and public service capacity among different regions, which need to start from the actual local conditions, explore effective ways to promote the mobility of labor and talents according to conditions. We can support places with conditions to experiment first, carry out institutional innovation on the premise of strictly abiding by the legal policy bottom line, explore differences in household registration education, employment and other fields, and improve the pilot error correction and incentive mechanism. We can encourage cross-regional and cross-departmental collaborative pilot projects, explore the reform of labor and talent mobility, training and use. We should strengthen the refinement of experience and policy transformation, upgrade the mature practices into institutional arrangements, and form replicable and popular practice models.
