Mention: The bold font on the diagonal is the root value of AVE, and the lower triangle is the pearson correlation of the dimension.

According to Table 4, every dimension corresponds to its own corresponding items. The standardized load of all factors is between 0.417 and 0.959, the combined reliability CR is greater than 0.7, and the convergence validity AVE is greater than 0.5, all of which are within the acceptable desirable range. Within the range, the discriminate validity starts with the square root on the diagonal. According to the recommendations of Fornell and Larcker (1981), but the square root value of AVE on the diagonal, and the lower triangle is the Pearson correlation between the dimension. The comparison results show that the root value of the dimension is greater than the correlation of other related dimensions, so the dimension has discriminate validity.
In brief, the measurement tools used in the study have already shown good reliability, structural validity, convergence validity, and discriminate validity, and overall reliability and validity are at a high level. Moreover, the measurement tools have been verified and used by researchers in different countries, regions, and different cultures, which shows that the quality of measurement tools is good enough. Based on the good quality of scale tools, the research uses a structural equation model, multiple regression model, and hierarchical regression model to further explore the influence relationship between the independent variables and dependent variables.
