摘要
选择试验模型法是目前国际上用于评估具有公共物品特性的自然资源和环境物品经济价值的一种相对较新的方法。论文以浙江省温岭市耕地资源保护为例,探讨选择试验模型法在耕地资源保护经济价值评估实践的可行性。在专家咨询和小组讨论的基础上,确定耕地景观、田间设施、土壤肥力和耕地保护费为温岭市耕地资源保护的4个属性。在对温岭市246名居民进行随机抽样调查的基础上,分析了温岭市耕地资源保护不同属性的价值以及耕地资源保护不同替代方案的相对价值。结果表明,对于温岭市全体居民来说,今后耕地资源保护的实施应该重点改善田间设施和提高土壤肥力,而耕地景观的改善也同样可以增加温岭市居民的福利水平。
The cultivated land resource has multiple functions and public good characteristics.Its ecological value and social value are usually ignored in the course of public decision-making,which has resulted in over-exploitation,excessive use and inefficient allocation of cultivated land in China.Economic valuation of natural resource or environmental goods that have public good characteristics has become a research frontier and hotspot of natural resource and environmental economics in the world.Choice experiment（CE） is a relatively new method that can be used to value the economic benefits of natural resources or environmental goods that have public good characteristics.This paper attempts to apply the CE method in Wenling city that aimed to understand Wenling residents＇ preferences for Wenling cultivated land resources protection programs.A random sample survey of 246 respondents in Wenling was conducted during the summer of 2010.Survey data was analyzed using the multinomial logit models.Results from the 246 in-person interviews indicate that Wenling residents preferred land field facility and land fertility improvement as well as landscape improvement for the protection of cultivated land resources in Wenling city.They would be willing to pay 17.54 yuan/household every month to improve the landscape,and would be willing to pay 37.96 yuan/household every month to improve the land field facility and would be willing to pay 31.43 yuan/household every month to improve the land fertility.Our results show that respondents＇ mean willingness to pay is affected by their socioeconomic characteristics.Those who have higher household yearly income,better education level,more knowledge on cultivated land resource protection and its non-market value would more prefer to choose the new alternatives that will have better land fertility,land field facility or landscape.The mean willingness to pay for the cultivated land protection program which will improve the land fertility,land field facility and landscape is 28.43 yuan/
