A social perspective of knowledge-based innovation: mobility and agglomeration. Introduction to the special section.

This paper introduces the special section, which aims to shed new light on the dynamics of knowledge generation and transfer with respect to human and geographical dimensions. We first provide a review of the state of the art in the two research areas, using bibliometric techniques, with the aim of tracing the evolution of the literature. We proceed by identifying some promising areas for future research and by explaining how the manuscripts included in this special section can contribute toward bridging some of the gaps that have emerged in the literature.
