Population scale mobility has always been sociology、Research hot spots in economics and other fields。Development economics explores the causes of population mobility from different perspectives、Process and Features，Like Lewis、The dual economic theory of Lanis-Fei Jinghan and others attributes population mobility to differences in income levels，The Todaro mobility model regards actual income multiplied by expected income as the probability of employment as the determinant of population mobility，Push-pull model and Carrington dynamic migration model also interpret the problem of population mobility from different perspectives。But in our country，Population scale mobility is not only affected by the laws of economics，A more significant factor is the household registration system。It is precisely because of the existence of the household registration system，The separation of households can not only reflect the scale of population mobility，It has also become one of the important phenomena affecting economic and bet365 code development。Main data display of the seventh national census，The number of separated households in my country in 2020 is about 4.9.3 billion，An increase of 2 compared to 2010.300 million，Growth 88.52%。The problem of separation of people and households is a major challenge for the refined governance of urban communities，Especially prominent in very large cities。

The dual urban and rural household registration system in New China was established to adapt to the unified grain purchase and marketing system during the first five-year plan，Relaxed after the reform and opening up。Great economic and bet365 code development over the past 40 years，Make the trend of population mobility more obvious，Further expansion in scale。It emerged simultaneously with the continuous flow of rural labor from rural to urban areas，It is the flow of urban labor force from economically underdeveloped small towns to economically developed large cities。

While economic construction has made great achievements，The reform of the household registration system obviously lags behind the needs of the times，Becoming an important part of the current deepening of reforms。The State Council promulgated the "Opinions on Further Promoting the Reform of the Household Registration System" in 2014，Since then, many cities have implemented the points settlement system，Promote the optimization of local population structure through active measures，Strive to solve the various bet365 code problems caused by household separation，And for the economy、Society、Attracting talents such as people’s livelihood construction。This is in two、Obvious results have been achieved in third-tier cities，But in very large cities，The phenomenon of household separation and related issues has become a major problem in urban governance。

The population of separated households is growing rapidly，Directly affects the construction of urban governance modernization system。In order to control the size of the permanent population in very large cities，Avoiding the responsibility to provide certain public services to the resident migrant population through the household registration threshold，This also means that the local government does not have complete management rights over the permanent foreign population，There are gaps in the urban governance system。This gives bet365 code security、bet365 code security、bet365 code stability、bet365 code equity and other hidden dangers，Urban governance is also facing increasingly complex risks、Vulnerability and uncertainty。Micro-local benefits obtained by local governments and registered population through household registration binding，Not enough to make up for the macro-bet365 code losses caused by household registration binding。Some scholars believe，The household registration system creates a gap between locals and outsiders、The institutional source of political and economic differences between old citizens and new citizens，And gradually reduce and eventually eliminate the differences in the permanent population due to household registration，“It is an important reform task common to all large cities，It is also one of the difficulties in modernizing the governance of very large cities”。Some scholars also believe that，The household registration system and the separation of people and households caused by it，Hindering the protection of residents’ rights and the realization of government management efficiency。

Separation of households leads to labeling of bet365 code membership，Not conducive to economic development and bet365 code stability。Currently，Individual large cities will housing、Medical、Important livelihood policies such as car purchase are closely tied to household registration。Take Beijing as an example，As of the end of 2019, there are 2153 permanent residents.60,000 people，Among them, 745 are permanent residents registered in other places.60,000 people，The points settlement policy allows 6,000 people to settle down every year (settlement rate 0.08%），At the same time, strictly control the talent introduction indicators of state agencies, institutions and state-owned enterprises。Among the huge permanent foreign population in Beijing，Existing low academic qualifications、Personnel with poor professional skills，There are also a large number of highly educated people、Personnel with professional skills。Foreign professional and technical personnel restricted by the settlement quota，Optimizing labor structure、Improve urban innovation capabilities、Promote economic and bet365 code development, etc.，Always plays an important and positive role，But their right to vote and participate in public affairs，And children’s education、Basic rights such as employment are subject to varying degrees of restrictions。

Is household separation still a factor influencing the continued shrinking of family size，Accelerate the deconstruction of traditional society，Bringing major challenges to public services and bet365 code service industries。In recent years, my country has liberalized its two-child policy，The seventh national census data does show an increase in the number of children、Proportion increase，However, the average number of households in the country has dropped to 2.62，Not only is the average number of people per household 3 lower than the sixth national census data in 2010.10，It is also significantly lower than the standard population of a normal nuclear family 3。The separation of people and households in economically developed areas is mainly manifested as "people are present in the household but are not"，In underdeveloped areas, it is manifested as "the household is here and the people are not here"，And the phenomenon of “empty nesters” and “left-behind children” throughout urban and rural areas。Traditional family functions include reproductive functions、Economic Function、Educational function、Nursing and support function、Storage private property function、bet365 code functions, etc.，The intergenerational inheritance of these functions ensures the traditional ethics of filial piety、The maintenance of bet365 code order and public order and good customs。Family is the most basic bet365 code unit，It is the starting point for socialization of bet365 code members，Undertakes many bet365 code functions both materially and spiritually。Family is not only related to the harmony and happiness of bet365 code members，It is also the fulcrum of grassroots bet365 code governance。The superposition of family deconstruction and aging society，To the construction of public service system and the development and transformation of bet365 code service industry, etc.，Bringing unprecedented multiple challenges。

Actively respond to the problem of the sharp increase in the population of separated households，Relieving the pressure brought by the long-term household registration system on bet365 code governance and bet365 code equity，Develop targeted population-related strategies and policies，Promote long-term balanced development of population，Avoid systemic bet365 code problems，There are at least the following approaches。On the one hand，Comprehensively promote the implementation of the rural revitalization strategy，Accelerate the modernization of agriculture and rural areas，Strengthen rural infrastructure construction，Improving the level of basic public services，Fundamentally solve the problem of excessive urban-rural expected income gap pointed out by the Todaro model，Reduce the willingness of rural labor force to flow into cities on a large scale。On the other hand，We must maintain and promote bet365 code justice、Protecting citizens’ equal rights and interests as the fundamental goal，For those who have long-term and stable jobs in very large cities、Highly educated、External talents with high professional skills，Relax settlement restrictions，Reduce the household separation rate as soon as possible。In addition，Legislation should be passed、Formulation and implementation of administrative regulations and related public policies，Optimize the structure and layout of the public service system，Improve the total quantity and quality of public services，Comprehensively improve the level of urban governance，Ensure the full implementation of "stimulating the enthusiasm of all people" proposed in the "14th Five-Year Plan" outline、Initiative、Creativity，Promote bet365 code equity，Improve people’s livelihood and well-being，Continuously realize the people’s yearning for a better life”。
