Fig. 3

The Interaction Effect of Medical between H_rate and CUP2 in model 6. Notes: 1. Figure 3 illustrates the moderating role of basic medical insurance coverage rate (medical) in the relationship between hospitalization rate (H_rate) and hedonic consumption expenditure (CUP2). 2. The x-axis represents the hospitalization rate (H_rate), while the y-axis displays the predicted values of hedonic consumption expenditure (CUP2). 3. The blue, red, and green lines in Fig. 3 correspond to basic medical insurance coverage rates of 0%, 50%, and 100%, respectively. These lines demonstrate how hedonic consumption expenditure changes as the hospitalization rate increases, allowing for a comparison of the differential impacts of hospitalization rates on hedonic consumption under varying levels of basic medical insurance coverage
