Circular Economy Business Models and Consumer Acceptance in the Electrical and Electronic Equipment Sector: A Comparative Study of Singapore and South Korea

This research project consists of two distinct studies. Study 1 seeks to explore design options for circular economy business models currently reported in the electrical and electronic equipment sector of Singapore and South Korea. Meanwhile, Study 2 investigates the extent to which consumers in both countries select different Product-Service System (PSS) elements, such as a product feature or service type, for refrigerators and washing machines. Study 1 employed a morphological analysis and a systematic review. Study 2 adopted an exploratory sequential mixed-methods design, consisting of a qualitative phase of focus groups followed by a quantitative survey phase that applies conjoint analysis and Kano modelling to the survey data. The project’s dataset includes research protocols and selected literature for Study 1, while for Study 2, it comprises demographic details of the participants, as well as their responses gathered from the focus groups, Kano modelling, and conjoint analysis for Study 2.

本研究项目包含两项独立子研究。研究1旨在探索当前新加坡与韩国电气电子设备领域所报道的循环经济商业模式的设计方案。研究2则探究两国消费者在冰箱与洗衣机选购场景中，对产品服务系统（Product-Service System，PSS）各类要素（如产品功能或服务类型）的选择倾向程度。研究1采用了形态分析法（morphological analysis）与系统综述法（systematic review）。研究2采用探索性序贯混合研究设计，包含两个连贯的研究阶段：首先开展以焦点小组访谈为载体的定性研究，随后实施定量调查；该定量调查阶段将联合分析（conjoint analysis）与卡诺模型（Kano modelling）应用于采集的调查数据。本项目的数据集涵盖研究1的研究方案与精选文献；针对研究2，数据集则包含参与者的人口统计学特征，以及从焦点小组访谈、卡诺模型分析与联合分析中收集的全部参与者反馈数据。
