It aims to address the theoretical gap in sustaining long-term consumer engagement on social commerce platforms by mitigating hedonic adaptation.A pilot study identified a vacation resort as the most suitable hedonic product for the main study. Participants were divided into high and low engagement groups to assess the impact of SCCs, PSV, and trust on HA. The manipulation check showed significant differences in engagement levels between the groups. Analysis revealed that high engagement participants had a higher hedonic response across all trials compared to low engagement participants. Regression results indicated that SCC1, SCC2, and SCC3 significantly alleviate HA, with SCC2 having the largest impact, followed by SCC1 and SCC3. PSV mediated the relationship between SCCs and HA, enhancing consumer engagement. Although trust positively influenced HA, its interaction with PSV did not significantly predict HA.These findings highlight the crucial role of SCCs and PSV in maintaining consumer engagement and satisfaction in digital contexts. The study provides insights for designing engaging social commerce platforms to mitigate hedonic adaptation, ensuring long-term success in the online retail environment.社群商務快樂適應社群商務構建社會知覺價值社會信任消費者參與Social commerceHedonic adaptationSocial commerce constructsPerceived social valueTurstConsumer engagement學術論文
