This Round Table discussion delves into the thriving secondhand market, highlighting the contrast between its success in China and the hurdles faced by platforms in the US. In China, online marketplaces like Xianyu and Zhuanzhuan have effectively partnered with physical stores, appealing to younger consumers who value convenience and sustainability. In contrast, US platforms grapple with profitability due to high operational costs, return rates, and logistical issues. The conversation also examines generational differences in secondhand shopping habits, the influence of fast fashion on the market, and the "green fatigue" that affects consumer behavior in Western countries.
