1.文章导读

为了最大限度地提高资源利用效率，循环经济使用了一系列回收方案。只有存在逆向分销渠道的情况下，才能实现最具价值的回收，即需要把二手产品进行回收再利用。回收服务的选择是消费者处置行为的最后一步。目前一些研究分析了消费者对产品处置的偏好，但大部分集中于城市生活垃圾或一次性用品，而关于电器电子产品（EEE）的研究比较少。

为了改进回收系统、设计消费者友好型服务以提高EEE的回收率，需要更好地了解消费者对回收服务的偏好。基于此需求，本研究主要解决了以下几个问题：(1)消费者偏好哪些回收服务属性；(2)产品类型是否对偏好有影响；(3)人群中是否存在显著差异。该研究考虑了家庭产生的三种EEE:手机、咖啡机和洗衣机，并对每一种选定的产品进行了基于选择的联合分析。

把经济体制转变为循环经济可以减少对原材料的依赖。循环经济要求二手产品通过逆向流通渠道进行回收和供应。 EEE是一个存在问题较多且回收不足的废物流。本文的目的是了解消费者对EEE回收服务的偏好。本文以手机、咖啡机和洗衣机为例，通过一项基于选择的联合分析，评估了布鲁塞尔消费者的偏好。研究结果强调了消费者偏好受价格驱动的本质。消费者不愿意选择焚烧，但对于再利用并没有明显偏好，甚至对于手机来说，他们更倾向于回收。这些结果也凸显了产品类型之间的巨大差异，尤其是服务类型:消费者对家用洗衣机回收的付费意愿较高，但对手机没有偏好。收入、家庭结构、职业以及储物间的可用性都会对几种回收服务偏好产生影响。但这些影响很小，并不涉及回收过程的偏好、回收者的身份、回收服务的价格以及预约条件。本研究的结果呼吁需要基于消费者的偏好来重新设计EEE分类和改进回收服务。

Changing our economic system into a Circular Economy can reduce our dependence on primary materials. Circular Economy requires used products to be collected and supplied through reverse distribution channels. Electrical and Electronic Equipment (EEE) is a problematic and under-collected stream. The aim of the present paper is to understand the preference of consumers for EEE collection services. Focusing on mobile phones, coffee machines and washing machines as examples, we assessed the stated preferences of Brussels’ consumers using a Choice-Based Conjoint analysis. The results obtained underline the price-driven nature of consumers’ preferences. Consumers also have a high reluctance for incineration but no significant preference for reusing over recycling, and even a preference for recycling in the case of mobile phones. These results also highlight the large differences among product types, especially for the type of service: consumers have a high willingness to pay for home collection of washing machines but have no preference for mobile phones. Income, household structure, professional occupation and availability of a storage room impact the preferences for several collection services’ attributes. These impacts are small and do not concern preferences for recovery processes, identity of the collector, price of collection services and appointment requirements. The results of this study call for a redesign of EEE classifications and for a refinement of collection services to incorporate consumers’ preferences.
