| 摘 要： | 本文分析了近30多年来广东省水稻的播种面积、产量和单产的变动趋势,并以比较优势理论为依据,运用综合比较优势指数法对广东省水稻生产的相对优势进行了研究。结果表明,广东省水稻的播种面积、总产量及在全国水稻播种面积中所占的比例均呈现下降趋势。1998-2009年间,广东省水稻的播种面积在南方13个水稻主产区中具有明显的比较优势,但水稻的单产相对较低,不具有效率优势。12年间水稻生产的平均综合优势指数为1.4626,在南方水稻主产区中位居第四。故应在保持水稻播种面积持续稳定的同时,采取多项措施,提高水稻的单产水平和综合生产能力,提升广东省水稻的比较优势和综合竞争力。

| Abstract: | Variations of rice planting area,total yield and yield per unit area in Guangdong Province during the latest three decades or more were analyzed and the comparative advantages of rice cultivation were investigated with the comprehensive advantage index based on the theory of comparative advantage.The results showed that the yearly rice sown area,total yield and its proportion in the whole national rice planting area dropped consistently.During the period of 1998 to 2009,rice sown area in Guangdong Province ... |
