基于New Cost DEA模型的棉花生产成本效率评价与分析——以新疆为例

运用New Cost DEA模型对新疆2010年22个产棉区的成本效率进行测算,结果显示:仅有1个产棉区是成本效率有效单元,其他21个产棉区都属于成本效率弱有效,其中配置效率是影响成本效率弱有效的重要原因。通过对各棉花产区的实际成本分解,可以看出除了配置效率原因导致成本增加是实际成本上升的主要原因外,技术效率和价格原因也导致了成本增加。为进一步降低实际成本,应从优化投入要素的配置结构、减少生产技术效率的冗余和降低生产投入要素的采购价格方面着手来降低成本,提高产棉区的成本效率。

Cotton production cost efficiency was calculated by the new cost DEA model in 22 cotton areas of Xinjiang in 2010. The results show that only 1 cotton area is the significant unit of cost efficiency and the others have weak cost efficiencies. The allocation efficiency is the main restricting factor in cost efficiency. In addition, the cost is increased owing to technical ef- ficiency and price. The actual cost can be reduced by means of optimizing input factor allocation, decreasing productivity redundancy and reducing purchase costs of input factors as to improve the cost efficiency in cotton areas.
