While networks are widely thought to enhance regional innovative capability, there exist few longitudinal studies of their formation and evolution over time. Based on an analysis of all patenting inventors in the U.S. from 1975 to 2002, we observe dramatic aggregation of the regional inventor...

Scholars from a variety of backgrounds – economists, sociologists, strategists, and students of technology management – have sought a better understanding of why some knowledge disperses widely while other knowledge does not. In this quest, some researchers have focused on the...

Strong patterns of concentration characterize the location decisions of development NGOs. Since current theories on non-profit location choice tend to neglect such tendencies, this article develops an evolutionary economic geography approach to non-profit organizations. It focuses on increasing...

The paper tries to construct the historical methodology for evolutionary economic geography. I elevate history to the methodological foundation of evolutionary economic geography, on which concrete research methods should be based. I explore how to evolution in economic geography by placing...

In this paper we measure technological relatedness between industries using a dataset on product portfolios of plants. For this purpose we first develop a general methodology to extract data on co-occurrences of classes (e.g. industries) in a single entity (e.g. a plant) to construct estimates...

Using dynamic panel data methods on UK counties (1841-1971), we investigate long-term employment dynamics in seven distinct local industries. We study how industries benefit from specialised environments (MAR), diverse local economies (Jacobs’) and large local markets (urbanization), and, in...

This paper analyzes the effects of the evolution of knowledge base in the manufacturing sectors on regional productivity growth. Knowledge is viewed as a heterogeneous asset, and an evolutionary perspective is adopted. The results of the empirical estimations corroborate the hypothesis that...

Despite the growing number of studies, still little is known about how network structures and proximity relations between linked actors evolve over time. Arguments are put forward for the existence of co-evolution dynamics between different types of proximity configurations within networks. An...

U.S. patent data and patent citations are used to build a measure of knowledge relatedness between all pairs of 438 major patent classes in the USPTO. The knowledge relatedness measures, constructed as the probability that a patent in class j will cite a patent in class i, form the links of a...

This paper analyzes the emergence of new technology-based sectors at the regional level. We focus on the specific case of nanotechnology as representative of an industry based on a technology still in infancy whose evolution can be reliably traced on the basis of filed patent submissions. We...
