Abstract

Cluster policy is designed to facilitate inter-firm networking. We examine industrial clusters in Japan based on firm-level transaction data. Firms in clusters expand transaction networks at higher speeds, but do so significantly only with firms agglomerated in Tokyo and not with local firms within the same region. By disaggregating firms according to their main bank types, we find that cluster firms expanding networks are mainly financed by regional banks and not by banks with nationwide operations. This suggests the importance of intensive relationships with main banks for inter-firm network formation.
