The data of health insurance expenditure and income of life insurance companies of China Insurance Regulatory Commission contains the figures of long-term health insurance, and long-term health insurance can not be used to calculate payout ratio by this simple method of dividing compensation by premium. For example, many products are guaranteed for life and the premium is 20-30 years. After the payment period is over, there is no way to divide the premium with 0 as the denominator. Theoretically or technically, we won't know what the real payout ratio of this business is until all long-term policies are terminated, that is, decades later. In fact, for long-term insurance, insurance companies use the actual occurrence rate rather than the pricing occurrence rate to observe the specific occurrence trend, and colleagues who do actuarial analysis in the actuarial department will do it regularly. But you can't calculate from the public data, because you don't know how to separate the different costs in the premium, and you don't have the pricing assumptions of each company.
