【摘要】：研究牧民对草原生态保护补助奖励机制的受偿意愿,对完善新一轮(2016-2020)的草原生态补奖机制具有重要意义。选取甘肃省玛曲县为研究区域,通过条件价值评估法(CVM)调查研究区牧民对当前实施的减畜政策的态度和受偿意愿,初步的统计分析发现,被访牧户中有59.81%的牧户愿意减畜,而40.19%的不愿意减畜的牧户认为当前实施的补偿标准太低,无法弥补因减畜造成的家庭经济损失。通过计量模型分析发现:牧户对减畜的支持态度主要与家庭劳动力负担系数、草场承包规模、联户情况、草场健康状况以及牲畜规模呈正相关,与草场租赁情况呈负相关;而牧户对减畜的受偿意愿额度主要由牧户受教育年限、家庭牧业收入、草场承包规模、牲畜规模以及联户情况等决定;根据CVM法估算了被访牧户的受偿意愿的期望值为E(WTA)=12.61元/亩,而通过Tobit模型计算了被访牧户户均理论受偿意愿值为WTA=12.16元/亩,但在政策实施中玛曲县草畜平衡奖励标准为2.18元/亩,进一步说明现行补偿标准明显偏低。
[Abstract]:It is of great significance to study the willingness of herdsmen to compensate for the reward mechanism of grassland ecological protection, which is of great significance to improve the grassland ecological compensation mechanism of the new round (2016-2020). Select Marqu County of Gansu Province as the research area, investigate the herdsmen's attitude to the current livestock reduction policy and their willingness to be compensated by the conditional value assessment method. The preliminary statistical analysis shows that 59.81% of the pastoral households surveyed are willing to reduce their livestock. However, 40.19% of the herders who are unwilling to reduce livestock think that the current compensation standard is too low to compensate for the family economic losses caused by livestock reduction. Through the analysis of econometric model, it is found that the support attitude of pastoral households to livestock reduction is positively correlated with the labor burden coefficient of the family, the scale of grassland contract, the situation of joint households, the health status of pasture and the scale of livestock, and is negatively correlated with the situation of grassland lease. The amount of compensation for livestock reduction is mainly determined by the number of years of education, the income of the family, the scale of grassland contract, the scale of livestock and the situation of joint households. According to the method of CVM, the expected value of the willingness to be paid was estimated to be 12.61 yuan / mu, while the expected value of willingness to be paid was calculated by Tobit model as 12.16 yuan / mu. However, in the implementation of the policy, the reward standard for grass and livestock balance in Maqu County is 2.18 yuan / mu, which further shows that the current compensation standard is obviously low.
