GEISAI自2001年開始，以每年兩次的頻率於日本舉行，至今已逾十年，2009年起原裝移植台灣，於台北市中心華山1914文創園區盛大開辦。GEISAI中文翻譯為「藝祭」，命名取自美術大學學園祭，由日本當代藝術家村上隆所領導的Kaikai Kiki公司所主辦，為一個讓各式各樣的藝術家齊聚一堂一同展覽的藝術活動。它不僅是「挖掘夢想出道藝術家的場所」，同時也是個「像跳蚤市場一樣輕鬆展示買賣藝術作品的場所」和「跟已開創的美術界接軌的新起點」。 時至今日，GEISAI儼然已成為台灣藝術家每年的一個重要活動。GEISAI最吸引人的莫過於其「無先前審查制度」，以及「黃金評審團」，提供藝術家、藝術相關人士與一般藝術迷相遇的場所，不僅給予對藝術有熱情者展演舞台，也造就了許多藝術新秀。 本研究得出幾點結論如下： 1. GEISAI的核心價值主張十年來皆本著「如何建立東方新型態的藝術市場」的態度去執行，從未改變。台日GEISAI由於國家習慣、資金組成不同，而有相對應的舉行方式。 2. 活動若能長久經營，必須堅持一核心的價值主張。明確的價值主張除能使活動更為聚焦外，也能持續吸引未被滿足的潛在消費者加入。 3. 具強烈信任感、合作無間的執行團隊為活動長期經營的要件之一。 4. 對實質付出大於無形收穫的活動而言，理想的堅持是持續經營的原動力。 / Since 2001, GEISAI has been held bi-annually in Japan for over 10 years. It took place at Huashan1914 Creative Park in Taiwan since 2009. The name GEISAI is derived from the Japanese word for "art festival." Such festivals would typically take place within a university or art school. It held by Kaikaikiki Co., Ltd belongs to Takashi Murakami. GEISAI presents a new art-collecting concept, allowing artists to exhibit their own works directly. It is a place where new artists can make their mark, where art work can be easily traded, and where the new and old can connect. Nowadays, GEISAI became an important activity of artists every year. The most attractions of GEISAI are "Non-Entry-Requirement" and "All-Star panel of judges". GEISAI provides a place where many artists gather to exhibit their works. It also provides artists and fans a place to meet face-to-face. More importantly, GEISAI provides new artists show-off opportunities and creates many new stars of art. The conclusions of this research can be summarized as below: 1. The core value proposition of GEISAI is based on "how to establish new ear art market" for 10 years. GEISAI&GEISAI Taiwan held in different way due to their national habit and capital composition. 2. Activity has to insist on its core value for the sustainable development. Specific value can not only focus on the activity but also attract unsatisfied potential customers continually. 3. A team with strong faith and cooperation is one of the key factors of sustainable development. 4. As an activity which its tangible devotion is more over than intangible income, the insist of ideal is the motivation of sustainable development.
