Abstract

As global growth has gradually declined, the Customer to Customer (C2C) market has expanded. And the growth potential of the C2C market is getting higher than in the past. Therefore, in this study, we examined what factors affect the price of used products within the C2C market. In order to examine the factors, we used data provided by Kaggle, which is a data science platform, and Mercari, Japan's largest C2C community marketplace platform. In research methods, the characteristics of the products were selected such as product categories, product status, shipping costs, product brands, and the data were analyzed using a linear mixing model to predict the price of C2C used goods. As a result, the variable that most affected the price was the shipping cost. When the seller paid for the shipping cost, the price would drop more than if the buyer had to pay. This study has been shown that the shipping costs is also an important factor in the used market, which can provide practical implications for customers of real transactions.

글로벌 저성장 시대가 지속되고 있는 현 시점에, Customer to Customer(C2C) 시장이 점차 확대되고 있으며, 앞으로의 성장 가능성도 증가하고 있다. 이에 따라 본 연구에서는 C2C시장 내, 태블릿PC 중고제품의 판매에서 가격에 영향을 미치는 요인을 파악하고자 한다. 이를 위해 일본 최대 C2C커뮤니티 마켓플레이스 플랫폼인 Mercari가 제공한 태블릿PC 중고거래 데이터를 분석하였다. 연구방법으로는 선형회귀 분석을 사용하였으며, 중고 거래가의 로그 변환을 종속변수로 하였고, 이에 영향을 주는 독립변수는 다중공선성 문제와 본페르니 수정을 통해 제품 상태, 제조사, ROM용량, RAM용량, 액세서리 포함 유무, 잠긴 상태를 선정하였다. 분석 결과, 제품상태 등급이 낮고 ROM과RAM용량이 클수록, Apple사의 태블릿PC 제품일 때, 액세서리가 있을 때, 중고 태블릿PC의 로그 가격이 높아지고, 태블릿PC가 잠겨있는 상태일 때는 그렇지 않을 때보다 로그 가격이 낮아진다는 것을 파악하였다. 로그 가격에 가장큰 영향력을 주는 변수는 RAM용량인 것을 알 수 있었다. 본 연구를 통해 판매자와 구매자의 경계가 불투명한 C2C 시장에서 중고 태블릿PC의 적절한 수준의 가격을 제공해 판매자와 구매자 모두에게 도움을 줄 수 있다.
