Development of China's maize industry, challenges in the future and policy suggestions.

In the past thirty years,China's maize production has been keeping growing,and now maize has become the largest crop in China in terms of both output and production area.Because the growth rate of maize demand is higher than that of production,China has become a net importer of maize since 2010,and the import volume has been increasing.This study used CAPSiM model projected China's maize future supply and demand.The results show that China's future supply and demand of maize will continue to grow,but demand will grow faster.China may have to import more maize in the future to fulfill its increasing maize demand.Based on discussions on the challenges of China's future maize production,this paper proposes policy measures to promote China's maize production in the next decades.
