Identifying and Ranking the World's Largest Clusters of Inventive Activity

Abstract

This paper presents an empirical approach to identifying and ranking the world’s largest clusters of inventive activity on the basis of patent filings. Patent data offer rich information on the locality of innovative activity. Many researchers have already made use of these data to study individual clusters or selected clusters within a particular region. Our approach goes beyond existing work by identifying and ranking innovation clusters on an internationally comparable basis.
