Abstract:

Abstract Due to early-rice surplus and corn shortage, it is necessary to restructure the gram production. One of the most important advice to restructure the production is what so called "corn substitution": that is to decrease early-rice production and increase corn production in Southern China. However, what is the im-planting impact of the advice, and how do we adjust the grain production? Based on a regional advantageous analysis in resources and market demand, this paper makes some new suggestions and alternative restructur-ing of the grain production in South China.
