家里有不用的书、衣服、CD等，你会怎么处理？有人可能直接扔了，而有的人则可能会在网上发个帖子低价转让或转赠。这种旧物再利用模式就是分享经济的模式之一。

The sharing economy (aka the shared economy) refers to economic and social systems that enable shared access to goods, services, data and talent. These systems take a variety of forms but all leverage information technology to empower individuals, corporations, non-profits and government with information that enables distribution, sharing and reuse of excess capacity in goods and services. A common premise is that when information about goods is shared, the value of those goods increases, for the business, for individuals, and for the community.

分享经济（sharing economy或shared economy）指能够让商品、服务、数据以及才能等有共享渠道的经济社会体系。这些体系形式各异，但都是运用信息技术让个人、公司、非盈利机构以及政府掌握大量信息以让他们可以分配、共享及再利用过剩的商品和服务。该体系的共同前提是，有关商品的信息被共享以后，该商品对商家、个人以及社区的价值也随之增加。

Sharing economy business models emerge from our oldest instincts as humans -– cooperation, sharing, generosity, individual choice and flexibility. Models include renting, bartering, loaning, gifting, swapping and forms of shared ownership such as cooperative structures. Many of the most popular models are based on what is called a "two-sided market" which is a market where an information technology-enabled platform is developed, built and maintained by a third party but the function of the platform is to enable sharing economy activities. The most popular structures include: P2P marketplaces, crowdfunding platforms, innovation marketplaces, government to business platforms, government to citizen platforms. (Source: Wikipedia)
