【摘要】：生态补偿是解决环境问题的有效方式,而确定补偿标准是其中最重要的指标之一,也是保证项目能长久有效实施的关键.拍卖方式能平衡生态系统服务提供者和支付者之间的成本效益,考虑自愿和公平的原则,是确定补偿标准的较好方法.通过构建不同风险偏好的拍卖投标者的最优报价模型,结合肃南县退牧还草生态补偿项目,分析了对保留价不同的预估范围下当地104户牧民的风险偏好和风险溢价差值.结果表明:当风险溢价差值为零、大于零以及小于零时,投标者分别为风险中性、风险厌恶和风险喜好的类型;肃南县参与此次拍卖竞标的牧民随着机会成本的增加,风险偏好从厌恶,到趋于中性,最后表现为风险喜好,其中当机会成本增加到一定额度时,风险偏好又从风险喜好反弹回风险厌恶再回到风险喜好;而随着对预估保留价不确定性程度增加,风险溢价差值表现为逐渐增大的趋势.另外,实证结果还表明,对于风险中性的投标者应公开保留价,而对风险厌恶者则应保密.
[Abstract]:Ecological compensation is an effective way to solve environmental problems, and the determination of compensation standard is one of the most important indicators, and it is also the key to ensure the long-term and effective implementation of the project. Auction can balance the cost benefit between ecosystem service provider and payer, and consider the principle of voluntary and fair. It is a better way to determine compensation standard. By constructing the optimal bidding model of auctioneers with different risk preferences and combining with the ecological compensation project of returning pasture to grass in Sunan County, the risk preference and risk premium difference of 104 herdsmen in different range of reserve price were analyzed. The results show that when the difference of risk premium is zero, greater than zero and less than 00:00, the bidders are risk neutral, risk aversion and risk preference, and the herdsmen in Sunan County participate in the auction with the increase of opportunity cost. Risk preference from aversion to neuter, the last performance is risk preference, where when the opportunity cost increases to a certain amount, risk preference rebounds from risk preference to risk aversion and then to risk preference; With the uncertainty of the estimated reserve price increasing, the margin of risk premium is gradually increasing. In addition, the empirical results also show that the risk-neutral bidder should disclose the reserve price, while the risk aversion should be kept secret.
