Article: Sure, but Who has the Energy? The Importance of Location for Knowledge Transfer in the Energy Sector
[show abstract] [hide abstract]
ABSTRACT: Using over 250,000 U.S. patent citations, we test whether knowledge transfers in the energy sector are sensitive to distance, and whether that sensitivity has changed over time. Controlling for self-citation by inventor, assignee and examiner, multivariate regression analysis shows that physical distance is becoming less important for spillovers with time.Environment & Natural Resources eJournal. 12/2011;
