The network of multiple markets is becoming more important, while the amount of vegetables traded through the central wholesale market system is decreasing. We investigated the structure of the current wholesale markets network using the daily price of radish at four branch markets in Tokyo Metropolitan Central Wholesale. We applied the vector error correction model (VECM). Based on the estimated VECM, we tested whether these markets were integrated and analyzed which market had a stronger influence on the others. The results suggest that these markets are integrated and that Ota has the strongest influence on the other markets except Kita-Adachi.
