The de- and re-regulation of the different network industries is an ongoing process at national and global levels. The question about the right mixture between market, economic, technical and social regulation remains wide open in all the network industries. The question becomes even more challenging when looking at recent infrastructure development as triggered by their pervasive digitalization. Not only are the different infrastructures transformed by their digitalization – e.g., digital transport, smart energy, etc. – calling for new approaches to regulating them, but moreover does digitalization become a phenomenon in its own right.
