4. RESULTS AND DISCUSSION
4.1 Descriptive Statistics and Correlation Analysis
Descriptive statistics including mean and standard deviation is depicted in Table 2. For the multicollinearity concerns, all correlation coefficients of independent variables are smaller than 0.8 and all variance inflation factors (VIFs) values are smaller than 10, indicating that there are no problems of multicollinearity of independent variables of the study (Hair et al., 2006). Table 2 shows descriptive statistics and correlation coefficients.
