With the increasing competition, most convenience stores have started to engage in cross-sectoral cooperation with different types of enterprises to enhance their own scale of operation, thereby expanding their market share and forming a common interest group. Therefore, the purpose of this study was to investigate the effects of cross-sectoral cooperation and service convenience on customer loyalty. This study was conducted with consumers who had visited family convenience stores as sampling. It found that: cross-industry cooperation has a positive effect on customer loyalty; 2. convenience of service has a positive effect on customer loyalty. This study suggests that convenience store chains should continue to cooperate with other well-known service industries and reduce the added value of time and after-sales service for consumers.
