Empirical Research on the Influences from Seed Subsidies and Labor Mobility on Food Yield in China

摘要

The paper puts forward countermeasures and suggestions on safeguarding national food security in terms of expediting promotion of subsidy variety, boosting land transfer, as well as speeding up new-type urbanization and others. Through investigating wheat production status to 581 peasant households in the north of Anhui Province, this study conducted empirical analysis to the influences from subsidy variety and labor mobility by means of expanding C-D production function. The result showed that the subsidies for growing superior grain cultivators have prominent yield-increasing effect to wheat yield; the labor mobility has no obvious impact to wheat yield and chemical fertilizer, pesticide, capital have obvious significance to wheat yield. Meanwhile economies of scale exist in wheat production.
