摘要
应用比较优势指数法对江苏省水稻生产进行比较优势分析。结果表明:江苏省水稻生产具有综合比较优势和规模比较优势,缺乏效率比较优势。1980～2010年江苏省水稻生产的综合比较优势指数和规模比较优势指数一直大于1,效率比较优势指数基本小于1,3个比较优势指数均总体上呈缓慢上升趋势;与省内主要粮食作物相比,2001～2010年水稻生产的平均综合比较优势和效率比较优势高于小麦和玉米,平均规模比较优势高于玉米而低于小麦;与全国其他9个水稻主产省相比,2001～2010年江苏省水稻生产的平均综合比较优势、规模比较优势和效率比较优势分别处于第7、第7和第5位。基于上述研究结果,提出了稳定规模比较优势,提高效率比较优势,以进一步提升江苏省水稻生产比较优势的对策建议。
The comparative advantage of rice production in Jiangsu province was analyzed with the method of aggrega- ted comparative advantage index. The results showed that rice production in Jiangsu Province possessed aggregated com- parative advantage and scale comparative advantage, but lacked efficiency comparative advantage. Aggregated comparative advantage index and scale comparative advantage index of rice production in Jiangsu Province from 1980 to 2010 were always greater than 1, efficiency comparative advantage index was basically less than 1, and three comparative advantage indices all had a slow rising trend as a whole; compared with other major grain crops produced in Jiangsu Province, aver- age aggregated comparative advantage and efficiency comparative advantage of rice production were higher than that of wheat and corn, while average scale comparative advantage were higher than that of corn but lower than that of wheat from 2001 to 2010; compared with other nine major rice producing provinces of China, average aggregated comparative advantage, scale comparative advantage and efficiency comparative advantage of rice production in Jiangsu Province from 2001 to 2010 ranked the seventh, the seventh and the fifth, respectively. Based on the results, countermeasures and sug- gestions were put forward to stabilize the scale comparative advantage, and improve the efficiency comparative advantage, which resulted in further enhancement of the comparative advantage of rice production in Jiangsu Province.
