市町村別住宅エネルギー消費原単位の推定: 住宅の環境負荷とその地域性に関する研究その1

摘要

This study proposed two statistical methods for estimating household energy consumption by each municipality in Japan. The first one was the methodology of creating final energy consumption models, unified statistical models F, and for local statistical models, restricted statistical models G, and there application method for each municipality in Japan. This study defined the P_i that is a coefficient of difference between places, and introduced some spatial statistical concepts for reflecting the regional characteristics and to improve precision. Finally, we estimated household energy consumptions by each municipality and described them by a GIS map separately for 3,319 locations in Japan. This study proposed a useful methodology of estimating household energy consumption by each municipality in Japan. However this method needs work for applying to remote islands. The second one is the methodology of the integrated use of similar studies and improves the precision of the estimated result. The method is a kind of asymptotic convergence method by applying Bayes Statistics. We applied this method to Kumamoto city and Minamata city, and showed the results. This has resulted in the realization of efficient integration of the findings of numerous studies.%全国市町村別の住宅の最終エネルギー消费原単位を推定するため,家計調査から都道府県庁所在都市について2000年〜2011年の原単位を求め，2種類の時空間統計モデルを作成した.1つは全国統一モデル群Fで，地域を限定せず全国の原単位が用途別に推定できる.
