Firstly, we analyzed the influence factors of HECP using univariate and multivariate analysis. DRG grouping was conducted according to the exhaustive Chi-squared automatic interaction detector（E-CHAID） model, using HECP as target variable. Finally we evaluated the grouping results using non-parametric test such as Kruskal-Wallis H test, RIV, CV, etc.RESULTS： The 6 DRGs were established as well as criterion of HECP, using age, sex, type of surgery and whether complications/comorbidities occurred as the key variables of classification node of senile cataract cases.CONCLUSION： The grouping of senile cataract cases based on E-CHAID algorithm is reasonable. And the criterion of HECP based on DRG can provide a feasible way of management in the fair use and supervision of medical insurance fund.展开更多
This paper investigates the causal relationship between the Urban and Rural Resident Basic Medical Insurance(URRBMI)reform and household consumption in urban China using data from the Chinese Household Income Project ...This paper investigates the causal relationship between the Urban and Rural Resident Basic Medical Insurance(URRBMI)reform and household consumption in urban China using data from the Chinese Household Income Project survey and employing combination of the propensity score matching and difference-in-differences methods.The results yield three conclusions.First,the reform affected both the amount and share of household consumption.Specifically,the reform led to an increase in total household consumption,encompassing both medical and nonmedical expenditures.Among these,the proportion of medical consumption increased,while the proportion of nonmedical consumption reduced.Second,the impact of the URRBMI reform varied across consumption categories within nonmedical expenditure.Specifically,consumption for education and entertainment industries are positively impacted by the URRBMI reform in terms of both quantity and proportion.Third,low-income households benefit more from the URRBMI reform compared to middle-and high-income households.The main channels through which the URRBMI reform affects household consumption were the price effect and the crowding out effect on precautionary savings.展开更多
