This research analyzed 5,002 households which responded to Korea Welfare Panel Study conducted from 2010 to 2013 and conducted in-depth analysis related to CHE. Catastrophic Health Expenditure(CHE) is defined if a household`s health expenditure against ability to pay is equal or greater than threshold and the threshold in this research is 20%. This research analyzed the factors influencing CHE recurrence as well as occurrence and expecially verified the statistical significance of CHE recurrence applying the concept of state dependence. The major results of this research are as follows. First, the influence factors of CHE occurrence and recurrence are different. Second, households which had experienced CHE showed high possibility of future CHE occurrence. In other words, state dependence in CHE exists. And the level of healthcare expenditure against ability to pay of households which experienced CHE recurrence showed high level of healthcare expenditure against ability to pay in future. Third, households which had insured by private health insurance showed low possibilities of CHE occurrence and recurrence. Fourth, the three severe diseases increased the possibilities of CHE occurrence and recurrence, but the diseases not included in the three severe diseases such as diabetes and kidney ailments also increased the possibilities of CHE occurrence and recurrence.
