Regionalization of Sustainable Agricultural Development of China on the Basis of Relative Superiority Assessment
基于比较优势的中国农业可持续发展区划

On the basis of relative superiority assessment, this paper achieves regionalization of sustainable agricultural development of China.Firstly, an index system of sustainable agricultural development of China is built, including 5 supporting subsystems of agricultural resources, agricultural development, environment and ecosystem, rural society, and science-education management, and 95 factors at provincial level are selected as basic indicators. Secondly, a relative assets/debt assessing method is used to gain relative net assets values (relative superiority) of every province or municipality directly under the Central Government at the 5 supporting subsystems and the total capability. Then the assessment results are graded and shown as distribution maps by GIS. Thirdly, according to the assessment result of sustainable agricultural developing capability, the whole nation is divided into 9 agricultural developing regions (first level) and 22 sub-regions (second level). The first level reflects each region's direction for sustainable agricultural development and issues' management. The second level reflects whether or not each sub-region reaches sustainable agricultural development and its degree. Thereby regionalization of sustainable agricultural development of China is set up. Based on the above-mentioned assessment and regionalization, this paper puts forward the target of sustainable agricultural development in China: (1) The eastern area of China must enhance its level of sustainable agricultural development, increase its science input, modulate its inner structure; and focus on intensive, commercial and green agriculture. (2) The central and western parts of China must change their situation firstly, and then improve their sustainable developmental level. (3) In western China development, the key policies are focused on ecological construction, producing input, social and scientific management in rural area.
