With the emergence of a series of physical sharing platforms such as Uber and Airbnb, the business model of the sharing economy (SE) is rapidly developing globally. Existing research on the sharing economy mainly involves three main aspects: the connotation of the sharing economy, the business model of the sharing economy, and the impact of the sharing economy. We begin by introducing the reasons why the sharing economy is booming and why customers from different positions participate in the sharing economy. Then we summarize the basic mechanisms of the consumer-to-consumer (C2C) and business-to-consumer (B2C) aspects of the sharing economy. Regarding the main causes of the sharing economy, we specifically focus on the impacts of the sharing economy on the environment, i.e., whether sharing economy is eco-friendly to the society. We consider product life cycle assessment (LCA) technology as one of the frontiers and key technologies in the fields of green design and green manufacturing. Furthermore, combined with the impact of COVID-19 on the sharing economy and the actual problems in real life, we present the future development directions of the sharing economy.

随着一系列的物理共享平台（如Uber和Airbnb）的出现，共享经济（SE）的商业模式正在全球快速发展。对共享经济的现有研究主要涉及三个方面：共享经济的内涵，共享经济的商业模式以及共享经济的影响。我们首先介绍共享经济蓬勃发展的原因以及来自不同位置的客户参与共享经济的原因。然后，我们总结了共享经济中消费者对消费者（C2C）和企业对消费者（B2C）方面的基本机制。关于共享经济的主要原因，我们特别关注共享经济对环境的影响，即共享经济是否对社会有利。我们将产品生命周期评估（LCA）技术视为绿色设计和绿色制造领域的前沿技术和关键技术之一。此外，结合COVID-19对共享经济的影响以及现实生活中的实际问题，我们提出了共享经济的未来发展方向。
