This study explains the concept of the incidence and intensity of Catastrophic health expenditure(CHE) in order to suggest the need for research on the intensity aspect that has been overlooked in existing domestic research fields, and to suggests that the results for each indicator are difference. This study compared the trends in the incidence and intensity of CHE using data from 2011-2016 of the Korean Health Panel, and calculated the concentration index using a single data in 2016 to derive the characteristics of each indicator. Finally, we analyzed the factors of CHE in aspects of incidence and intensity through the panel two-part model. As a result, firstly, while the incidence had little change over time, the intensity was significantly decreasing. Second, in the concentration index, both indicatos were concentreated in the low-income group, but the incidence was vulnerable to the threshold. Third, factors influencing the incidence and intensity of CHE differed from each other. In particular, it was found that the incidence was more associated with demographic factors or prevalence than insurance coverage. Existing studies on CHE in Korea have been analyzed only in terms of incidence. In the future, research on the intensity of CHE should be actively conducted.
