大豆综合比较优势时空特征动态变化研究

Studies on Time and Space Variation of Comprehensive Comparative Advantage of Soybean in Jiangsu Province

提出了一种研究大豆生产时空特征的新方法,在对大豆进行综合比较优势分析的基础上,完成对其定量分析的规范化评估,从不同的侧面对江苏省各地级市大豆生产的综合比较优势的时空特征动态变化进行了研究。

In this paper, a new analyzing method of time and space variation of soybean production in Jiangsu province, which was based on normal analysis of comprehensive comparative advantage （CCA） of soybean,was presented, which satisfied the control and management requirement of soybean production in this province. The results indicated that the normal CCA was influenced strongly by several natural and non-natural factors and can be used for scientific management of soybean production. Thus, the reasonable distributive adjustment and land infrastructure construction and scientific management of soybean production were major factors to increase soybean production level in this province.
