A Time-Series Approach to Changes in Second-Hand Consumption Perception

This study examines changes in consumer perception regarding second-hand consumption in a time series manner. The research method applied text mining to newspaper and consumer perception over three periods (from 2017 to 2019, from 2020 to 2022, from 2023 to 2024 July). The results are as follows. The amount of environmental news was not large between 2017 and 2019, but the amount has increased exponentially since 2020. Because of this, consumers would have been able to watch a lot of environmental news. Additionally, perceptions of second-hand clothing have also changed. From 2017 to 2019, the perception of low prices gradually changed to fashionable goods after 2020, and the perception of second-hand consumption shifted to environment and sustainability. In addition, it was confirmed that interest in professional platforms is now emerging as an online business. This can provide implications for second-hand fashion that extends product lifespan as concerns about environmental sustainability increase in the future.
