How do the complementary elements influence the value of multi-homing products in platform ecosystem?

In the field of product development, there is an increased focus on product complementarity. This study explores how the elements of multi-homing complementarity in the platform ecosystem (complementarity type, degree of platform complementarity, and degree of complementarity with other products) affect perceived product value. The data comprise 248 samples of smart-home multi-homing products, collected from the Amazon EC platform. The results indicate that prioritizing the degree of platform complementarity can increase the number of reviews, while prioritizing the degree of complementarity with other products can reduce that number. Focusing on unique complementarity can have a negative impact on ratings. Regarding the interaction term, the interaction of unique complementarity and the degree of complementarity with other products increases the number of reviews. Thus, unique complementarity should be included in the product-development process to ensure product quality and enhance sales.
