This study explores the various components of agricultural production in China from the land utilization perspective, involving changes in grain production per unit area, multi-cropping index, and adjustment of agricultural structure. Compared with the record values, different research methodologies are used to analyze the po- tential of above three components. The results indicate that grain production potential of 65.68×109kg was unexploited in 2006, in which 45.8×109kg came from the restructuring in agriculture. So we can infer that the reduction of grain production in China could be primarily attributed to agricultural restructuring in recent years. So the productive poten- tial can be fully restored by increasing agricultural investment, or recovering agricultural structure in favorable condi- tions. So we can say that China’s current condition of food security is good.展开更多

However, China＇s sustainable agricultural development faces severe tests such as agri-tech ＂short slabs＂ and poor collaborative operation. The 12＇h Five- year Plan period will bring both strategic opportunities and challenges. Brisker market demands and more agricultural inputs, a higher technical level and better policy regimes will drive development. On the other hand, agriculture will be confronted with more resource and environment constraints, fewer traditional comparative advantages and hidden hazards, etc. Over the next five years, China should stay its course to agricultural modernization based on its national conditions and the sustainable development concept and establish a ＂broad interpretation of grain security＂ to improve the productivity, risk- resistance capabilities and market competitiveness of its agricultural industry.展开更多
