中国粮食生产区域分化特征和成因的实证研究

对中国在1990年和2002年粮食生产的区域分化状况进行统计分析的结果表明,工业化和城市化的发展,以及农产品市场形成条件下,稻米生产的区域分散特征、小麦生产的区域集中特征以及玉米播种面积的集中和生产产量的分散特征日益明显。计量检验显示,人均承包经营耕地面积和种植业收入比率是影响粮食生产区域分化的最主要的两个因素。

Empirical Study on Reasons and Characteristics of Regional Differentiation of China's Food Supply

Using the indexes of LQ and ID, the paper makes a statistical analysis of regional differentiation of China's food supply, with the data support from year 1990 to 2002. Meanwhile, multi-regression and key- factor regression statistical analysis was given. The results show that paddy and corn production become decentralization, while that of wheat goes obviously centralization. The contracted plantation per capita and crop income ratio are two factors, which affect the regional differentiation of food supplies.
