Following the 8th Conference on Regulation of Infrastructures, which took place on June 20 and 21, 2019 with a particular focus on the key challenges of digitalisation for traditional network industries in the transport, telecoms, water and energy sectors, four papers were selected for this publication due to their topical relevance. This special issue opens with an introductory article by the Members of the Scientific Committee of the conference, Professors of the Florence School of Regulation, Montero and Finger, who consider digital platforms as the new network industries and explore the network effects created by platforms. Fuentes et al. looks at the electricity sector, which is navigating major disruptions that are changing the regulatory and business landscape. The paper addresses whether these changes would help or hinder electrification, taking transportation as an example. Becchis, Postiglione and Valerio examine how platforms are giving rise to a series of regulatory challenges, with a focus on their legal definition, labour-related issues in the digital sphere and the role of data between privacy protection and competition. Knieps analyses the problem of division of labour among all-IP broadband network providers, virtual network service providers and platform operators concomitant with the implementation of adequate governance structures. Ducuing analyses the phenomenon, when several (contemplated) data sharing legal regimes appear to essentially recognise and regulate data as an infrastructure, although without explicit reference to this notion. Her research is based on three cases, namely the Open Data and PSI Directive, the on-going institutional discussion on the governance of in-vehicle data and the freshly adopted regulation of data in the Electricity Directive.
