A description of the work: This study focuses on CSR strategy using the programs of corporate-NGO partnerships from FamilyMart, the second-largest convenient store chain brand in Taiwan. In total, nine NGO programs were identified in the 2020 FamilyMart’s CSR report. The qualitative case study research was conducted and combined with documentary analysis. The data was collected from public documentaries, such as academic papers, CSR reports, corporate websites, press articles, and promoting videos online. The study applied resource-based theory to examine the contribution level on forming corporate’s sustained competitive advantages of different types of partnerships. Also, by implementing CSR approach analytical framework, the programs were analysed the intentions and implications of each type of partnership. The analyse showed that there is the possibility of transition from one type of partnership to the other one if the initial cooperation was based on a strategic CSR approach and both sectors were able to leverage and complement each other.
