Abstract: Regional specialization and regional division are important symbols of agricultural modernization. And they are also unavoidable for China’s agricultural development in the future. Since it is influenced by marketization of agricultural production and some policy factors such as cultivated land protection, agricultural subsidies and price protection, currently the direction of regional specialization and regional division is unclear in China. However, the centralized trend of agricultural production provides important clues to this question. In this paper, three main grain crops, rice, wheat and corn, are taken as the research object. Based on the provincial grain production in China from 1981 to 2013, the centralization index was adopted to reveal the evolution characteristics and evolution trend of regional centralization of the grain production in China. The results indicated that the centralization degree of grain production increased obviously. Besides, wheat production had the highest degree of centralization among the three grain crops, and presented a stable trend of centralization. However, the centralization degrees of rice and corn production both experienced a U-shaped change process, illustrating that rice and corn production had undergone space restructuring during this period. According to the trend, rice production centralized in Heilongjiang, Hunan and Jiangxi; wheat production centralized in Henan, Shandong, Anhui and other traditional wheat production regions; and corn production centralized in Heilongjiang and Inner Mongolia. Those results implied that specialized regions of grain production were likely to be formed in these areas and the surroundings. Strengthening the basic construction of farmland in these areas will help to promote regional specialization and regional division of China’s grain production.

Key words: centralization degree, grain production, regional division, regional specialization
