【摘要】The development of new industries demands access to local capabilities. Little attention has yet been paid to the role of spillovers from neighbour regions for industrial diversification, nor has the role of network linkages between neighbour regions been investigated. As the spread of capabilities has a strong geographical bias, we expect regions to develop new industries in which their neighbour regions are specialized. To test this hypothesis, we analyse the development of new industries in US states during the period 2000-2012. We show that a US state has a higher probability of developing a comparative advantage in a new industry if a neighbour state is specialized in that industry. We also show that neighbour US states have more similar export structures. This export similarity seems to be explained by higher social connectivity between neighbour states, as embodied in their bilateral migration patterns.
