The Constructive Effects of Algorithms on Adolescent Consumption Patterns

In the digital age, short video platforms, particularly TikTok, have emerged as a significant driving force influencing adolescent consumption behaviors, while profoundly reshaping their consumption patterns. However, existing research has paid less attention to this emerging consumer sector. This study employs a mixed-methods approach combining In-depth interviews, questionnaires and participatory observations methods to investigate how TikTok's algorithmic mechanisms reconstruct traditional consumption behavior among adolescents. The findings reveal that adolescent consumption on short video platforms is characterized by impulsive purchasing, high-frequency micro-spending, influencers and socially endorsed purchases, and decentralized consumption. In terms of influencing mechanisms, platform algorithms guide adolescent consumption through user data analysis, content recommendation, and contextual media strategies. Furthermore, the platform leverages psychological drivers, behavioral reinforcement, and promotional strategies to further consolidate and intensify these consumption patterns. To effectively address the impact of algorithms on adolescent consumption behaviors, this study proposes strategies such as optimizing algorithm design, enhancing media literacy, and strengthening multi-stakeholder education to help adolescents develop healthy and rational consumption habits.
