摘要

本研究以東京都的商圈分析做為案例研究，提出一個使用人口移動資料在空間中劃分研究單位，並且標記單位特徵的過程。研究方法使用核密度估計(Kernel Density Estimation, KDE)以及階層式分群方法(Hierarchical Clustering)逐步劃分研究單位、伽瑪混合模型(Gamma Mixture Model) 標記單位特徵。此過程得到的結果，再利用邏輯斯迴歸模型(Logistic Regression Model)解釋影響單位特徵表現的重要變數。研究結果顯示在東京都的重要幹線包含:中央線快速(JC)、武藏野線(JM)以及京葉線(JE)附近被標記為非在地商圈。此類型商圈吸引較多四十歲以上的職業人口和女性，且除了步行以外，使用各項運輸工具的比例皆較高。本研究使用新提出的方法和移動資料劃分出的研究單位，避免了主觀決定單位尺度的方式。

The study takes a trading area analysis for Tokyo city as a case study to propose a process for the study area to group into each unit and then label the characteristics. We used Kernel Density Estimation (KDE) and Hierarchical Clustering for the grouping phase and Gamma Mixture Model for labeling. After the process, we built the Logistic Regression model to describe the difference between a local and non-local shopping region in Tokyo city. The results of the study show that the non-local shopping regions are surrounding by several railway lines include Chūō Rapid Line (JC), Musashino Line (JM), and Keiyo Line (JE). This type of shopping region attracts more employed people with age over 40 and women. In addition to walking, the proportion of other modes of transport used is higher than in the local shopping regions. This study proposed the new method for grouping the mobility patterns of customers to delineate the boundary of the shopping districts.
