In Akihabara, where various specialty stores accumulate, people gather searching for limited and rare products and exchange them to share their hobbies and interests outside the store, forming a kind of public sphere.

 This paper clarifies the mechanism of forming "the place for exchanges of goods".

 To grasp this mechanism that are common in the outdoor space of Akihabara is also important in considering the value of downtown, which used to be discussed with words "bustle" and was not considered its social meaning.

 1) Geographical characteristics of group staying behavior on the street

 By patrolling Akihabara district, the distribution of places for exchanges of goods on the street was clarified from the wide-area viewpoint. Through this survey 12 locations were extracted where "appreciation and exchange" activities were concentrated, and from these locations it became clear that place for exchanges of goods tend to be formed in the near ground where manga, anime, and game content is sold.

 2) Behavior and spatial transformation of places for exchanges of goods

 From the fixed-point observation investigation, the change of the range in which space for exchanges of goods forms and the change of the behavior were analyzed. As a result, special characters of places where exchanges of goods are likely to happen were grasped from a microscopic viewpoint. It has become clear that place for exchanges of goods occurs avoiding the flow of people. It was also confirmed that the larger the number of members, the more they stayed in the environment surrounded by street objects.

 3) Behavioral psychology of people who form places for exchanges of goods

 Hearing investigation clarified what kind of behavioral psychology were seen behind forming the places for exchanges of goods, and what kind of actions were done for making their own place on the street. As a result, two types of actions were identified: "exchange of goods" and "exchange of information". It was confirmed that places for exchanges of goods occurs not only in search of a consensus of interests, but also in search of mutual empathy through the exchange of information in which people can deepen their knowledge of hobbies and preferences. It also became clear that they formed or joined in places for exchanges of goods with 9 kinds of behavioral psychology.

近年、日本各地の自治体や任意団体では、地域の魅力を発信するためのさまざまな取り組みが行われている。その中でも、写真や動画を使った地域PRは広く行われているが、競合が多いことや消費者がそうしたメディアに慣れていることもあり、地域PRが注目されづらいという現状がある。本研究では、地域資源を知るためのツールとして「おもちゃ」を利用し、地域資源の魅力を知る方法を提案する。

There is “Anthropocene” as the word which indicates the phase on which the mankind has the important influence which puts global environment and expresses a geology like new epoch. How should an area correspond to global risk in this new epoch.

“Anthripocene” will expand the interaction of the environment like pluralism with man. How is an area placed at the time when the cyber space of IoT and DX (digital transformation) connects with a global network beyond the geographical restrictions.

This time, It was considered about the state of the change in an area at the metamorphoses inside of the world as “Anthropocene” with a smart city (technical apparatus as a city), life log (digital freedom and right) and an offset (financial ecology) as the keyword.

As a result, we named the matrix for mapping the unknown era “CHI-IKI”, and concluded that the Communal hub function “OpenAlley” was important for resilient regional regeneration as the actor.

近年，不確実性を伴う販売手法（例：ガチャやくじ引き）が注目され，日本国内でも多くの企業がその手法を採用している。しかし，既存研究では，リスト内の全商品が同ランク（例：同じ商品の異なる味）の場合は，不確実性を伴う商品が好まれる一方で，異なるランク（例：異なるグレードかつ異なる味）の場合は，避けられる傾向が示された。このため，異なるランクにおける不確実マーケティングと消費者の反応については十分に解明されていない。そこで，異なるランクの条件下で，リスト内から何が選ばれるか分からない不確実性が伴う商品（ランダム商品）の選択意向に影響を与える要因として，希少性メッセージと結果の不確実性を楽しませる要素に着目し，分析を行った。結果，両要因は選択意向を有意に高めることが示された。さらに，これら要因の交互作用を検討した結果，時間的制約がランダム商品の選択意向に与える正の影響を，結果の不確実性を楽しませる要素が弱める有意傾向が示された。本研究は，不確実性を伴う販売手法に対する消費者の心理的要因を明らかにし，理論的・実務的な示唆を提供するとともに，長期的影響を探る今後の研究の必要性を指摘する。
