“…Third, for the six main propositions and a total of 12 sub-propositions proposed in the conceptual model of free-to-fee switch, even if they are supported by similar research evidence in previous literatures, most of them are not consistent with our findings. Therefore, it can be divided into three categories to illustrate: - the model has clear support evidence from previous literature, which is consistent with our findings, including P2 (Varadarajan, 2020), P5 (Katila and Ahuja, 2002; Luo et al , 2018), P6 (Sheth et al , 2020), P6a and P6d (Liu and Atuahene-Gima, 2018);
- there are similar studies in the previous literature, and some cases have similar research evidence but are not completely consistent, including P1 (Mustak et al , 2021), P1a (Durst and Runar Edvardsson, 2012; Zawaideh et al , 2018), P1c (Johansson et al , 2019), P3 (Zaim et al , 2018), P4 (Petrakis and Kostis, 2012), P6b (Chaithanapat and Rakthin, 2020) and P6c (Chen and Huan, 2020; Chaithanapat and Rakthin, 2020); and
- no similar literature has been found so far, including P1b and P1d .
