Abstract

This study explores the impact of CSR initiatives (CSRI) and CSR-supportive behaviors (CSRSB) on consumer brand loyalty (CBL), with social media influencer credibility (SMIC) as a mediating factor. A survey of 550 Chinese sports brand consumers was conducted, and structural equation modeling (SEM) was employed for data analysis. The results show that CSRI significantly influences CSRSB (β = 0.667, t = 27.538, p < 0.001) and SMIC (β = 0.685, t = 13.793, p < 0.001). Additionally, CSRSB positively affects SMIC (β = 0.472, t = 13.793, p < 0.001) and CBL (β = 0.232, t = 5.425, p < 0.001). The mediation analysis confirms that SMIC partially mediates the relationship between CSRI and CBL (β = 0.209, t = 4.830, p = 0.001), highlighting the importance of influencer credibility in consumer trust and brand loyalty. The findings suggest that brands should strategically collaborate with credible influencers to amplify CSR messages and enhance long-term consumer engagement. The study provides valuable insights for businesses on optimizing influencer marketing strategies to strengthen CSR-driven brand loyalty.
