Abstract

This article distinguishes between intra- and inter-megalopolitan social proximity and assesses the relative importance of such two types of proximity on a city’s inventive performance. Using invention patents data in China, we find that internal social proximity rather than external social proximity has a positive and statistically significant effect on the inventive productivity of cities within a megalopolis. Our article contributes to the growing literature of co-invention networks and urban innovation by focusing on the megalopolitan level and highlights the importance of coordination between megalopolises.
