Patent citations and the geography of knowledge spillovers: disentangling the role of state borders, metropolitan boundaries and distance
Author: Singh, Jasjit ; Marx, Matt ; Fleming, LeeINSEAD Area: Strategy Series: Working Paper ; 2010/03/ST Publisher: Fontainebleau : INSEAD, 2010.Language: EnglishDescription: 25 p.Type of document: INSEAD Working Paper Online Access: Click here Abstract: We employ a regression framework based on choice-based sampling to estimate the probability of knowledge flow, measured using patent citations. This serves to extend research on the geography of knowledge spillovers, which has hitherto analyzed metropolitan, state or national effects only separately, through a simultaneous consideration of these geographic units. Fine-grained inventor location data are used to further disentangle the role of different geopolitical boundaries and distance. In addition to national border effects, we find a puzzling persistence of state-level spillover localization, a finding not explained merely as an aggregation of metropolitan effects, or outcome of spatial or social proximity.
