With the increasing trend of rural laborers engaging in non-agricultural employment, significant changes hove occurred to the income structure and production and management mode of forming, An increase in the age of the agricultural workforce has also occurred, resulting in a shortage of agricultural labor, creating concern regarding food production and security. Using the 2010 survey dot of the Rice Research Institute,of Liaoning province, this study established a rice production function and analyzed the influence of rural-urbon migration on rice production from the perspective of production factor inputs and the family life cycle. These empirical results indicate that the aging agricultural workforce has no obvious negative impact on rice production, because of the important role years of experience ploys in rice production and a reduction in body strength demand stemmed from agricultural mechanizotion, The positive influence of non-agricultural income obtained by migrant workers appears to offset the negative effect of on production, Young formers tend to hove on extensive management role in agriculture as a result of their negative opinion of forming and increased income from non-agricultural sources. Conversely, older formers ore not as likely to seek migrant labor elsewhere as they tend to maintain their traditional dependence on agriculture, and are also deterred by the uncertain expectation over working remittance, In conclusion, the migration of people from forms to cities is not found to be harmful to rice production. A current obstacle involves developing a means of adapting forming production and management with migrant work, meeting the new demands for food production as well as utilizing the financial resources offered by migrant work on food production, rather than reducing the number of migrant formers.
