### Benefits  
#### 5.5.1 Effect Cost Ratio  
Based on the effectiveness calculation results in 5.3.5, combined with the cost present value calculation results in Table 19, the effectiveness cost ratios of the four plans are calculated according to Equation (26). The calculation results are shown in Table 26.
