共享 (gòng xiǎng) literally combines 共 (gòng), meaning 'together' or 'joint', and 享 (xiǎng), meaning 'to enjoy' or 'to partake'. Together, they convey the idea of jointly accessing, using, or benefiting from something — not merely dividing ownership, but enabling multiple people to use the same resource simultaneously or in turn. It’s widely used in modern Chinese for digital services (e.g., shared bikes, cloud documents) and social contexts (e.g., sharing experiences, knowledge, or responsibilities).

The term carries a positive, cooperative connotation and often appears in compound nouns like 共享单车 (shared bicycles) or 共享办公空间 (co-working spaces). While it can function as a verb ('We share this document'), it frequently serves as a modifier in noun phrases. It emphasizes mutual access rather than transfer of ownership — distinguishing it from words like 转让 (to transfer) or 分享 (to share in the sense of distributing or telling).
