Abstract
With the rise of the SDGs, the innovations in reuse, sharing and rental economy are attracting attention
so the purchase and sale of second-hand luxury branded goods is growing significantly. Companies
handling second-hand luxury goods have created new markets by systematically training skilled
appraisers with abundant product knowledge and the ability to distinguish between genuine and fake
items, by making a company go public, by conducting mergers and acquisitions, using Information
Technology, developing overseas markets, and improving logistics efficiency. In this paper, we will discuss
case studies of major companies using Everett Rogers' "Five Adopter Categories" model as an analytical
frame.
