초록

본 연구는 새롭게 떠오르는 재테크 방법 중 아이템의 희귀성을 이용하여 출시가보다 비싼 가격에 재판매하는 리셀(Resell) 재테크에 주목하였다. 리셀 시장은 패션 분야를 중심으로 세계적으로 시장 규모가 급격히 성장하고 있을 뿐만 아니라 국내에도 열풍이 불고 있으나 아직까지 체계적인 리셀 시장에 대한 실증적인 분석은 부족하다. 이에 본 연구는 리셀의 대표적 사이트인 StockX의 스니커즈 데이터를 활용하여 리셀 시장에 관심 있는 사용자들에게 기본적인 가이드라인을 제시하고 리셀 시장의 진입장벽을 해소하고자 한다. 약 150만 개의 데이터를 수집하여 XGBoost 알고리즘과 Prophet 모형을 통하여 분석을 진행하였다. 분석 결과 리셀 거래에 유효한 영향을 미치는 요인들을 각 변수 별로 파악할 수 있었고 어떤 종류의 스니커즈가 리셀 거래를 하기에 적합한지 확인할 수 있었다. 또한 스니커즈들의 과거데이터를 통해 미래의 가격을 예측하여 추후의 수익성을 예상할 수 있었다. 본 연구는 아직 시작 단계인 리셀 분야에 대한 실증 분석을 기반으로 시장 진입 및 활용에 대한 가이드라인을 제시하고 더 나아가 마니아층 위주로 점유되던 리셀 시장을 활성화할 수 있을 것으로 기대한다.

This study noted the emergence of the Resell investment within the fashion market, among emerging investment techniques. Worldwide, the market size is growing rapidly, and currently, there is a craze taking place throughout Korea. Therefore, we would like to use shoe data from StockX, the representative site of Resell, to present basic guidelines to consumers and to break down barriers to entry into the Resell market. Moreover, it showed the current status of the Resell craze, which was based on information from various media outlets, and then presented the current status and research model of the Resell market through prior research. Raw data was collected and analyzed using the XGBoost algorithm and the Prophet model. Analysis showed that the factors that affect the Resell market were identified, and the shoes suitable for the Resell market were also identified. Furthermore, historical data on shoes allowed us to predict future prices, thereby predicting future profitability. Through this study, the market will allow unfamiliar consumers to actively participate in the market with the given information. It also provides a variety of vital information regarding Resell investments, thus. forming a fundamental guideline for the market and further contributing to addressing entry barriers.
