## 2 Literature Review
The estimated and statured value of SRMR is 0.031, which meets the standards. The threshold for the NFI value is higher than 0.80, and the founded value for NFI is 0.962 (see Table 5). The value of \(\chi\)2 is 782.744 for the saturated model. The overall model fit results indicate that the model's fitness is good and acceptable. For structural hypotheses testing, path coefficient (\(\beta\)) standard errors, t-values, and \(p\)-values are stated in Figure 5 and Table 6, where the path coefficient specifies the change in outcome variable due to the predictor variable for every 1-unit, t-value is the coefficient divided by its standard error, and \(p\)-value is a significance level. The statistical results for H1 show the positive effect of EBPr on OPT, with 0.149 coefficient (\(\beta\)) value, 4.341 t-value, and \(p\leq 0.05\), confirming the proposed relationship. The calculated coefficient (\(\beta\)), t-value, and \(p\)-value are 0.072, 2.28, and <0.000, which claimed a significant impact of EBPr on SUP for hypothesis H2, which is supported. EBPr had a favorable impact on EnS and supported the fictitious H3 hypothesis, with calculated coefficient (\(\beta\)), t-value, and \(p\)-value of 0.257, 9.931, and <0.000, respectively. The results show that the direct and mediating effects of OPT are significant and supported. The direct effects of OPT on SUP and EnS are significantly positive and validated with \(\beta\)(0.233), t-value(7.368), and \(p\leq 0.000\) for hypothesis H4; and \(\beta\)(0.259), t-value(9.509), and \(p\leq 0.000\) for hypothesis H5. The mediating effect of OPT among EBPr and SUP (H6) is positive with \(\beta\) = 0.035, t-value 4.123 and \(p\leq 0.000\), which significantly confirms the proposed hypothesis. The mediating effect of OPT among EBPr and EnS (H7) is positive with \(\beta\) = 0.039, t-value = 4.154, and \(p\leq 0.000\), which significantly confirmed the proposed hypothesis. The direct effect of SUP for H8 was positive and significantly confirmed. The statistical result for H8 is (\(\beta\) = 0.231, t-value = 8.730, and \(p\leq 0.000\)). Therefore, the mediating effect of SUP among EBPr and EnS (H9) is positive with \(\beta\) = 0.054, t-value = 5.435, and \(p\leq 0.000\), which significantly confirmed the proposed hypothesis. Last, the mediating effect of SUP among EBPr and EnS (H10) is positive with \(\beta\) = 0.017, t-value = 2.237, and \(p\leq 0.05\), which significantly confirmed the proposed hypothesis. According to the results, the mediating role of SUP is higher than the mediating role of OPT, which is possible due to the enhanced quality of environmental features linked with all business operations. However, all hypotheses were significantly positive and confirmed with the proposed hypothesis. \begin{table}
