Fig. 2

The Interaction Effect of basic medical insurance between H_rate and CUP1 in model 5. Note:1. Figure 2 illustrates that the participation rate in basic medical insurance (medical) plays a moderating role in the influence of the hospitalization rate (H_rate) on the survival-oriented consumption expenditure (CUP1). 2. The horizontal axis in Fig. 2 represents the explanatory variable, the hospitalization rate (H_rate), while the vertical axis represents the predicted value of the explained variable, the survival-oriented consumption expenditure (CUP1). 3. The blue, red, and green broken lines in Fig. 2 represent the changes in survival-oriented consumption expenditure as the hospitalization rate increases when the participation rates in basic medical insurance are 0, 50%, and 100%, respectively. This is used to compare the differences in the impact of the hospitalization rate on survival-oriented consumption under different coverage rates of basic medical insurance
