Query: The Multilayer Structure of Corporate Networks   Various company interactions can be described by networks, for instance the
ownership networks and the board membership networks. To understand the
ecosystem of companies, these interactions cannot be seen in isolation. For
this purpose we construct a new multilayer network of interactions between
companies in Germany and in the United Kingdom, combining ownership links,
social ties through joint board directors, R\&D collaborations and stock
correlations in one linked multiplex dataset. We describe the features of this
network and show there exists a non-trivial overlap between these different
types of networks, where the different types of connections complement each
other and make the overall structure more complex. This highlights that
corporate control, boardroom influence and other connections have different
structures and together make an even smaller corporate world than previously
reported. We have a first look at the relation between company performance and
location in the network structure.
