Paper long abstract:

 In 2017, the number of migrants had reached 244 million in China. Rural migration reshapes the economic and social structure of China, as well as the agricultural in China.The research based the survey of the 454 rice farmers from Southern China in2015, we collected the data about household demographic information, land, income activities, cropping patterns of rice, remittance and how to use it, and also the framers' cognition for the impact of migration member for the household. We found the direct impact of rural migration for the household is the labour using patterns. Every household have more than one labour migrated to the city, which account for more than 50% of household total labour. The migrants mostly are young member (20-50), male or female, and the left-behinds are older or old female (more than 50) and the children or students. Old people are taking responsibility for caring the children and farming. Farmer is allocating more labor on nonfarm sector, which lead to less labor allocated in the farm sector. Labor saving cropping patterns or technology spread very quickly, such as zero-tillage, direct seeding, machine using or lower intensity cropping and etc. rice cultivators pay more attention to the production efficiency and profit, larger scale or median size family farm become more and more popular. Most farmer household replied that there was no impact of migration members on the left-behinds' agricultural production, but the remittance mostly is used in living cost or house building and the children's education.
