| 摘 要： | 以产量优势指数为比较优势计量指标,分析了江苏省淮安市淮阴区主要的8种农作物在1995~2000年间产量在国内和省内绝对优劣势的变动情况,发现除个别作物的产量绝对优劣势随着时间的推进在个别时期会发生较大的变化外,多数作物的产量绝对优劣势基本保持相对稳定。根据该8种农作物在1995~2000年间的产量优势指数均值及其相对优势排名,还对产量国内和省内比较优势进行了对比分析,结果表明相对于不同高层次区域,作物的比较优势会表现出较大的差别。

| Abstract: | Taking yield advantage index as quantitative index, the author analyzed the changes on absolute of domestic and presidial advantage of yield of the main crops in Huaiyin during 19952000. As time went on, although yield absolute advantage of exceptional crop was found to change greatly, most crops showed relative stability. According to the mean value of the yeild advantage index of these crops and their relative advantage rank during these period, the contrast was carried out between yield comparative advantage of domestic and presidial. The result indicated the comparative advantage of crops showed great distinction comparing with the different areas of high level. |
