Fig. 5

The Interaction Effect of NRCMS between H_rate and CUP2 in model 8. Note: 1. Figure 5 illustrates the moderating effect of the New Rural Cooperative Medical Scheme (NRCMS) enrollment rate on the relationship between inpatient admission rate (H_rate) and hedonic consumption expenditure (CUP2). 2. The x-axis in Fig. 5 represents the inpatient admission rate (H_rate), while the y-axis shows the predicted values of hedonic consumption expenditure (CUP2). 3. The blue line in Fig. 5 represents the variation in hedonic consumption expenditure as the inpatient admission rate increases, for NRCMS enrollment rates of 2% and 100%, highlighting the moderating role of NRCMS enrollment rate in this relationship
