"The concept of sharing is as old as human civilization. It has existed for centuries but has recently attracted a lot of attention focused on the ways in which digital technologies have opened avenues for sharing and collaboration. In cities, new digital technologies are revolutionizing the ways in which we use transport, housing, goods and other services – whether driven by economic or social reasons. Sharing has also changed the way we work. The sharing economy has virtually disrupted all sectors, creating a multitude of platform-based marketplaces that connect individuals, enterprises and communities at a peer-to-peer level. The sharing economy is making cities redefine land-use strategies, minimize their costs, optimize public assets and collaborate with other actors (for-profits, nonprofits, social enterprises, communities and other cities) in developing policies and frameworks that encourage continued innovation in this area."
