Migrant workers refer to agricultural registered permanent residence laborers who work in local township enterprises or enter cities and towns. Migrant workers are the product of the unique urban-rural dual system in China, and they are a special social group in a special historical period. Migrant workers are divided into broad sense and narrow sense: broad sense includes two parts, one part is rural labor force who has been employed in local township enterprises, and the other part is rural labor force who has left home to engage in secondary and tertiary industries; The narrow sense of migrant workers mainly refers to the latter part. According to the investigation of relevant departments, the number of migrant workers in a narrow sense is about 654.38+0.2 billion, and the number of migrant workers in a broad sense is about 200 million. That is, migrant workers, agricultural registered permanent residence, but engaged in non-agricultural work; They live and work in the city and have made great contributions to the development of the city. In some people's minds, migrant workers are derogatory terms. In fact, migrant workers are not necessarily special people who live in rural areas but work in cities. With the improvement of China's household registration system, people who have rural household registration and work in cities, including junior and senior high school graduates who have rural household registration and work in cities after graduating from colleges and universities, will no longer have urban and rural household registration. Migrant workers are synonymous with migrant workers and the main force of urban economic development. Generally speaking, it refers to farmers and workers. Of course, it is said by China people. In America, there is no such name as farmer. They are collectively called farm workers. Literally, migrant workers and farm workers seem to have little difference, but after careful study, they are two completely different words. First of all, in terms of identity, migrant workers are farmers and farm workers are workers; Secondly, at work, migrant workers do the work in the city and farm workers do the work on the farm. Ai Jun, a sociologist and critic on issues concerning agriculture, rural areas and farmers, believes that under the dual household registration system implemented in China for many years, what we call "migrant workers" actually refers to "workers in agricultural registered permanent residence who are engaged in non-agricultural work in cities".
