We investigate ''dual headquarters involvement'', i.e., corporate and divisional headquarters' simultaneous involvement in innovation development projects hosted by subsidiaries of multibusiness firms. Drawing on selective hierarchical involvement theory and the literature on subsidiary network embeddedness, we analyze 83 innovation projects in 22 multibusiness firms and find that the number of partners in the projects, rather than subsidiary intra-and inter-divisional embeddedness acts as a driver of dual headquarters involvement. We do however find that intra-and inter-divisional embeddedness is positively related to dual headquarters involvement when the number of partners in the innovation project is relatively large. These results lend support to the idea that parenting in complex organizations entail complex headquarters structures. Our results suggest that we need to go beyond simple conceptualizations of headquarters and that considering different dimensions of the innovating subsidiary's network helps in explaining dual headquarters involvement.
