“…Previous researchers found out the determinants of consumer RPI such as consumer satisfaction (Liao, Lin, Luo, & Chea, 2017;Wu et al, 2014;Zhang et al, 2011), consumer trust (S. Chou & Chen, 2018;Fang et al, 2014), the perceived service quality (S. Yang, Lu, Chau, & Gupta, 2017), and the ethics of e-retailers (Elbeltagi & Agag, 2016;Limbu, Wolf, & Lunsford, 2011). Moreover, in the EC context, with the faceless interactions with retailers, there exists always a level of perceived uncertainty (Fang et al, 2014;Pavlou, Liang, & Xue, 2007) but hitherto very few research explores the effect of perceived uncertainty on RPI such as Cheng, Liu, and Du (2017) and Chiu, Chih, Ortiz, and Wang (2018). It is necessary to do more research on the correlation between perceived uncertainty and RPI.…”
