The insight (obvious in retrospect) underlying Airbnb’s model – and the burgeoning sharing economy in general – is that the world is replete with under-utilized assets and resources. How much time do we spend actually using the things – whether cars, bicycles, apartments, vacation homes, tools, or yachts – that we own?
在对Airbnb模式——新兴共享经济体——的深层次思考（按其日新月异的发展速度显然只能是回顾）看来，世界上充斥着尚未充分利用的资产和资源。试想在那些自己名下的东西上——无论是汽车、自行车、公寓、度假别墅、工具或游艇——我们实际花费了多少时间？把写字楼或教室利用起来的话，一个晚上又能创造多少价值？
