Phygital retail experiences connect physical and digital worlds together to create unique experiences among customers. Despite the widespread uses and applications of phygital retailing, the involvement-patronage link remains unexplored. This paper thus aims to make up this gap by examining the effects of customer involvement on their patronage intentions in the phygital retail context. More specifically, building on the social exchange theory, this paper mainly addresses the effects of five dimensions of involvement on customer engagement; and the influence of customer engagement on their patronage intentions in the phygital retailing. The role of customer innovativeness as a boundary condition is also explored. Data were collected from 237 customers who experienced phygital retail stores and analyzed through structural equation modeling. The results show that five facets of involvement (i.e., risk importance, risk probability, sign, interest, and pleasure) affect customer engagement, which eventually affects customers’ patronage intentions of phygital products. This study further identifies that the effects of each dimension of involvement on customer engagement are higher (lower) among the customers with high (low) innovativeness. The findings of the study offer significant theoretical and managerial implications.
