In addition, because only a small percentage of respondents had
purchased physical products in the m-commerce environment, the

to generate bootstrap samples for CFA. In the future, when physical
product shopping becomes more common in the m-commerce
environment, its support services should be re-examined with a
larger sample, which would allow a CFA to be carried out directly
