Risk Characteristics of Catastrophic Health Expenditure in Multidimensional Borderline Poor Households in China

Background: Ending poverty and realizing common prosperity are the essential requirements for the localization of Marxism in China. The ongoing COVID-19 pandemic in the post-poverty era further aggravates the risk of catastrophic health expenditure for borderline poor households and increases the uncertainty of returning to poverty due to illness, potentially undermining decades of hard-won efforts to eradicate poverty in China. Methods: Based on the latest data released by China Health and Retirement Longitudinal Survey (CHARLS) database, this paper uses the Logit model to empirically explore the risk characteristics of catastrophic health expenditure of multidimensional borderline poor households based on identifying multidimensional borderline poor households. Results: The results show that factors such as family income level, child support, and medical insurance have different impacts on catastrophic health expenditure, and the risk of catastrophic health expenditure of multidimensional borderline poor households is much higher than that of non-multidimensional borderline poor households, and there is a certain difference between urban and rural areas. Discussion: The government should strengthen and improve the social security system and health service system, such as medical insurance, and more resources should be allocated to multidimensional borderline poor households, especially in rural areas.
