Although the decline in the incidence of catastrophic health expenditures (CHEs) in China is encouraging, this issue remains important. On the basis of considering selectivity bias and heterogeneity, we applied propensity score matching (PSM) to analyze the 2018 data of the Chinese Family Tracking Survey. We assigned CHE household and non-CHE household to the treatment group and the control group respectively, and used non-random data to simulate a randomized trial to investigate the impact of CHE on household consumption in China. The results of this study indicate that, when the threshold is set at 40%, the consumption of households experiencing CHEs (CHE household) is significantly lower than that of households not experiencing CHEs (non-CHE households) and that CHEs have a significant negative impact on other household consumption and a significant impact on household property and debt. This effect still exists when the threshold is set lower, with household essential consumption most affected. The occurrence of CHEs lead to a reduction in household consumption and a significantly worsening financial situation for CHE households, impacting the basic quality of life of the families. Therefore, it is necessary to further reform the medical and health system to reduce high medical expenses.
