Comparison Analysis of Land Price Fluctuation in Tokyo Metropolitan Area

Abstract

We compare the land price time-series data of cities in Tokyo metropolitan area from 1993 to 2006 and plot groups of cities whose fluctuations are similar each other on a map. It is difficult to illustrate time-series data on a map directly because we have to treat it as the third dimension. But illustration of cities owning similar land price fluctuations jointly is useful for analyzing on change of land price change. We use annual increase rates as data of change of land price. Significance test is used to judge agreement between of city's average annual increase rates. Then we have found that cities reducing land price drastically indicate close fluctuation patterns but cities whose land price are falling little or rising present various land price changes.
