Abstract
This study proposes a new Cluster Quotient (CQ) to highlight the cluster characteristics and their effect on regional innovation systems based on all US Metropolitan Statistical Areas (MSAs) in 2014. This study finds that San Diego, CA plays an important role in biotechnology industries, and the CQ index would be a better method to measure the degree of clusters than the Location Quotient index (LQ) given that the CQ method is based on the definition of a cluster and strongly correlated with high industry quotient MSAs. The study also highlights that biotechnology clusters have a positive impact on patents. An increase of 1% of the CQ generates an increase of 0.25% of patents. The result highlights that biotechnology clusters play an important role in regional innovation systems and need to be seriously taken into consideration in the field of urban planning.
