Abstract: This study discussed the herdsmen's income under the dual background of the implementation of subsidy and reward policy for grassland ecological and the fluctuation of mutton prices,and discussed the influence mechanism of mutton price fluctuation on the effect of policy implementation. The results showed that the core of herdsmen's production decisions was based on creating the highest income. The fluctuation of mutton prices directly affected herdsmen's productive work behaviors,and had a significant positive impact on herdsmen's income. The incentive effect of policy was periodical,and incentive degree was a reverse trend with the mutton price. The "precious to sell" behavior made herdsmen to face huge financial liabilities crisis,and enter into a blind subsequent development. Therefore,the implementation of the subsidy and reward policy for grassland ecological protection should be connected with the market mechanism in order to achieve significant incentive effect,promote the change of herdsmen's production behavior,and ensure that they have stable income.

Key words: Subsidy and Reward Policy for Grassland Ecological Protection, Mutton Prices, Herdsmen's income, Productive Work Behaviors

摘要： 本文对草原生态保护补助奖励政策实施、肉羊价格波动双重背景下的牧民收入进行了研究；讨论了肉羊价格波动对政策实施效果的影响机制。结果表明，创造最高收入是牧民生产决策的核心；肉羊价格的波动直接影响牧民生产行为，与牧民收入呈显著正相关；政策的激励作用存在阶段性，激励程度与肉羊价格的变化趋势相反；牧民的“惜卖”行为使其面临巨大的金融负债危机，后续发展容易进入盲区。因此，草原生态保护补助奖励政策的实施要与市场机制挂钩，才能实现显著的激励作用，促进牧民生产行为的转变，保证牧民收入稳定。
