摘要

利用数据包络分析(data envelopment analysis

DEA)方法中的CCR模型

以家庭牧场经营草地面积、牲畜数量和生产性支出作为输入项

以家庭人均纯收入、人均消费支出、草地质量状况作为输出项

对内蒙古白音锡勒牧场30个调查样本进行了2级有效评价和目标改进研究。(1)生产效率的高低与草场规模有关

规模小(

200 hm

)其生产效率相对较高;(2)理论上

在维持草地质量状况不变的前提下

实现第2级DEA有效

输入项指标分别减少24.28%

21.83%和28.62%

输出项前两个指标分别增加0.78%和0.91%。实现第1级DEA有效

输入项指标分别减少49.86%

47.29%和60.79%

输出项前两个指标分别增加33.50%和7.06%;(3)加强并优化家庭牧场的经营管理

提高生产效率

是挖掘家庭畜牧业潜力

推进牧区生态环境建设的重要途径之一。

Abstract

Using grassland area

stock number

and productive expenditure as inputs and per capital annual net income

life expenditure

and grassland quality as outputs

we analyze 30 household pastures in Baiyinxile of Inner Mongolia by means of CCR

a model of data envelopment analysis(DEA)

and get the improved values of indicators.Results show that production efficiency is correlated with the grassland area possessed by households.The area of grassland less than 200 hm2 has high production efficiency.Under the assumption of no change in grassland quality

the two-level DEA validity suggests that the three input indicators decrease by 22.28%

21.83%

and 28.62%

respectively

and the first two output indicators increase by 0.78% and 0.91%

respectively.Moreover

the 1st DEA validity shows the three input indicators decrease by 49.86%

47.29%

and 60.79%

respectively

and the first two output indicators increase by 33.50% and 7.06%

respectively.Optimizing management and enhancing production efficiency in household level may play an important role in mining the potentials of household pastures and improving eco-environmental construction of natural grassland areas.
