The Network Structure of the Wholesale Market Systems in the Tohoku Region

A Network Analysis of Intermarket Transfers

Abstract

This study investigated the network structure of the wholesale market systems in the Tohoku region, using a network analysis of transfer volumes for vegetables and fruits. Our analysis revealed that a network centered on the Sendai market has long been established for vegetables and fruits, but a network for fruits disappeared in 2020. Additionally, our findings suggested that network density and degree centrality may be changed due to an increase in bilateral trading and disparity among markets.
