Influences of outflow of rural labor force on grain production: evidence from China
(2.Sustainable Development and New-Type Urbanization Think Tank, Tongji University)
【Abstract】Grain security is a core problem of issues concerning agriculture, countryside and farmers in China, and the outflow of rural labor force may have a significant influence on grain security. This paper used the panel data from 2001 to 2013, based on the extended C-D production function to make an empirical analysis of the outflow of rural labor force’s influences on grain production and its regional differences. The results showed that the outflow of rural labor force had a remarkable negative influence on grain production in the main sales areas of grain. However, it had no significant influences on grain production in major grain-producing areas and areas with the balance between production and sales. Fully considering the difference of resources endowments and regional characteristics in different areas, making different policies of labor mobility and grain security will be beneficial to ensure the safety of China’s food supply.

. ① According to the definition of the United Nations’ World Food Program (WFP), grain security in a broad sense includes two aspects as the follows. The first is security of the capacity to supply grain; the second is security of the ability to get grain. Grain security in a narrow sense only refers to the former (Wang, 2011). This paper takes the narrow sense and analyzes security of grain supply. [^Back]
