A new article “Urban Sharing in Smart Cities: The Cases of Berlin and London” has been published as part of Urban Sharing and Sharing and the City projects. The article develops a conceptual framework that specifies the roles that cities play when governing urban sharing: city as regulator, city as provider, city as enabler and city as consumer. It explores similarities and differences for these roles in the cities of Berlin and London. Both cities indirectly support urban sharing through smart agenda programmes, which aim to facilitate ICT-enabled technical innovation and emergence of start-ups. However, programmes, strategies, support schemes and regulations aimed directly at urban sharing initiatives are few. Berlin is sceptical towards urban sharing organisations, while London took more of a collaborative approach. Implications for policy-makers are discussed in the end.
