The source is an installment of an IT journalist's newsletter focusing on key concepts in Chinese technology, specifically examining "社区団購" (community group buying). This business model, similar to a co-op, involves community "leaders" organizing neighborhood orders for delivery from major platforms, which gained prominence during the 2020 pandemic. The newsletter explains that major Chinese tech companies are investing heavily in community group buying not only for its immediate business potential in rural and urban areas but also as a strategy to target the rapidly aging population and the diminishing labor force. Furthermore, it posits that these community hubs could eventually be leveraged to provide essential community services like elder care, medical assistance, and household help, aligning with the tech industry's goal of using business to solve social issues.
