北京自2010年起开始实施家庭餐厨垃圾源头分类工作，但居民的参与率却不尽如人意。本研究的目的是根据改进的家庭餐厨垃圾源头分类管理策略来确定居民的偏好。我们根据居民的年龄水平，确定临时样本中居民对源头分离服务的偏好以及他们接受服务属性补偿的边际意愿。我们使用多项 Logit 模型对通过选择实验收集的北京市海淀区和东城区 394 名居民的数据进行分析。结果表明，青、中、老年居民对服务属性的偏好存在差异。低补偿并不是促使中青年居民接受分居服务的主要因素。然而，平均而言，他们中的大多数人更喜欢频繁、夜间、塑料袋属性且没有教练的服务。这项研究表明地方政府有潜力相应地改善当前的分离服务。
A source separation program for household kitchen waste has been in place in Beijing since 2010. However, the participation rate of residents is far from satisfactory. This study was carried out to identify residents’ preferences based on an improved management strategy for household kitchen waste source separation. We determine the preferences of residents in an ad hoc sample, according to their age level, for source separation services and their marginal willingness to accept compensation for the service attributes. We used a multinomial logit model to analyze the data, collected from 394 residents in Haidian and Dongcheng districts of Beijing City through a choice experiment. The results show there are differences of preferences on the services attributes between young, middle, and old age residents. Low compensation is not a major factor to promote young and middle age residents accept the proposed separation services. However, on average, most of them prefer services with frequent, evening, plastic bag attributes and without instructor. This study indicates that there is a potential for local government to improve the current separation services accordingly.
