摘要
应用数据包络技术对我国1978-2007年八个棉花主产区的效率进行了估计.应用多目标规划的方法给出了我国2007年5亿元棉花补贴在偏重效率、偏重公平和效率公平兼顾三种情形下的分配额度.并在考虑了棉花产量不依赖进口,国家粮食安全稳定,农民获得合理收益,地区补贴均衡性等因素下推广了该模型,运用改进贪婪算法求解出各省补贴额.得出如下结论和建议:我国棉花生产补贴实际分配中比较注重公平,而缺乏效率,应重点加大对新疆等种植结构较为单一的棉花主产区的补贴力度,加大对长江流域的棉花补贴以显著扩大棉花种植面积.
We estimated the efficiencies of the eight cotton-growing provinces （autonomous region） by using data envelopment model （DEA） and employing the data from 1978-2007. And we calculated the subsidy quota on cotton under the conditions of effficiency-priority, fairness priority and giving attention to both in 2007 by using multiple objective optimization method. Moreover, we promoted the model on the considerations of non-reliance on imports, national grain stable safe supply, reasonable income for farmers and subsidy balance among provinces （autonomous region） by improved greedy method. We therefore come to the conclusion that our national actual distribution of cotton-growing subsidy is slanted toward fairness while lacking efficiency. The policy need Xinjiang and the subsidy on Yangtze River basin acreage of cotton-growing area. to intensify＂ the subsidy on main cotton-growing area as cotton-growing area, thereby significantly extending the
