How does the spatial mobility of population affect social economy?

Population mobility can accelerate regional exchanges and promote economic development; The progress of production technology can accelerate economic development-floating population-floating population who has not achieved household registration transfer.

Judging from the history of population migration in the past hundred years, large-scale population migration only occurred in the 1980s, and this migration is not limited to the change of household registration, so there are many different views on the definition of population migration in the field of demography. Starting from the time, space and purpose of population migration, Peng Xun can divide the existing definitions of population migration into three schools: broad, middle and narrow. Among them, liberals focus on the spatial displacement of population or the change of regional and geographical distribution from the spatial attribute of population migration. Starting from the purpose attribute, the middle school believes that the purpose of migration is to settle down or live. The narrow school uses two or three of the three attributes to define population migration. All three factions agree that moving to a place with a long distance and a long purpose of living is population migration. However, the three factions have different views on short-term business trips, work, vacations, tourism or seasonal, periodic and round-trip population movements. Liberals think it belongs to population migration, while middle-narrow ones think it belongs to population migration, and the corresponding population should be called floating population. Yang Yunyan and others believe that, generally speaking, floating population refers to those temporary population movements, but under the current circumstances, the commonly used concept of "floating population" includes all population movements that have not gone through the formalities of "household registration transfer", no matter whether this flow is short-term or long-term. According to the data, there are two main types of rapidly increasing population mobility: one is the urban functional floating population that increases with the economic development. Their stay in the city is generally short, and the flow direction of such floating population is determined by the urban function and urban radiation range, and its temporal and spatial distribution is relatively balanced; The other category is the labor force that enters the city to look for job opportunities. This kind of "floating population" is large in scale, stays in cities for a long time, and its flow direction is relatively concentrated, thus causing great social shocks. And the latter is usually called "temporary population" or "foreign population" according to the household registration status. Because this special group conforms to the basic characteristics of population migration in demographic research, they are also regarded as a special form of migration, that is, "informal migration" compared with "planned migration" The difference between them and the planned migration is mainly reflected in the difference of household registration status. Because hukou still plays a fundamental role in urban social and economic life, "informal floating population" can't enjoy the same opportunities and rights as "regular" residents in cities and towns to obtain means of subsistence and means of production, thus forming different immigrant groups with different hukou status in employment opportunities, industry and occupation mobility, welfare and social security. Taking Wenzhou, Zhejiang Province as an example, the floating population has played a great role in the construction of material civilization and spiritual civilization in Wenzhou.

Wenzhou has a floating population of 1.2 million, which has become the main force of Wenzhou's light industry and private enterprises. Its products are not only sold well all over the country, but also exported to foreign countries, such as Zheng Taihe Delixi products in Yueqing and Kangnai leather shoes.

Migrant workers have also played an important role in Wenzhou's municipal construction. Even in the New Year, they stick to the front line and only invite their families to Wenzhou for the New Year. Almost all pipelines of water and electricity, telecommunications and cable TV in Wenzhou are installed by migrant workers. Migrant workers brought local traditional cultural customs, improved Wenzhou's cultural taste and enriched Wenzhou's cultural life.

In their own words, Wenzhou is indeed their second hometown.
