| Abstract: | ABSTRACT An empirical regularity designated as the Number‐Average Size (NAS) Rule was first identified for the case of Japan by Mori, Nishikimi, and Smith , and subsequently extended to the United States by Hsu . This rule asserts a negative log‐linear relation between the number and average population size of cities where a given industry is present. In this paper, we utilize the cluster‐identification methodology developed by Mori and Smith to sharpen this notion of “industrial presence” by focusing only on cities that constitute at least part of a significant spatial agglomeration for the given industry. Our key result is to show that the NAS rule continues to hold (even more strongly) under this sharper definition. |
