摘要: 1992~1998年平均,我国12个棉花主产省(区)的粮棉单产比和植棉相对效益分别为1.94~7.24和0.95~5.41。经统计分析,这一单产比和相对效益每上升1,一个省1999年与1992年棉花产量之比就分别下降34.0个百分点、上升48.3个百分比。据此比较优势分析,在1999年我国棉花总产下调的形势下,甘肃、新疆宜保持原有产量水平,江苏、浙江、山东、河北、四川5省宜适当下调,而江西、安徽、河南、湖南、湖北5省则宜酌情处理。基于近期国际棉花市场形势的变化,作者认为,与其它省份一样,2001年甘肃、新疆的棉花产量也有较大的上调空间。

Abstract: In 1992-1998, mean unit yield ratios of food grain to lint cotton and cotton-growing profits relative to other agricultural activities ranged from 1.94 to 7.24 and from 0.95 to 5.41 in 12 major cotton-producing provinces, respectively. By statistical analysis, every 1 increase in the ratio will probably cause a 34.0% decrease and 48.3% increase in the ratio of cotton yield in 1999 to that in 1992, respectively. Based on this analysis of comparative advantages in the 12 provinces, under the nation-wide condition of reducing cotton production, it is reasonable to maintain the production levels in Gansu and Xinjiang, reduce the production to rational levels in 5 provinces of Jiangsu, Zhejiang, Shandong, Hebei and Sichuan, and adjust properly the production levels in the other 5 provinces of Jiangxi, Anhui, Henan, Hunan and Hubei. Considering the change in international market in the near future, the authors believe that cotton yield in Xinjiang and Gansu will further increase, and keeps the pace with the national production in 2001.
