In 2021，the development of health insurance in China faced transformation pressure. Although the premium income still achieved positive growth，the growth rate slowed down significantly. Long-term health insurance has maintained dominance，but new premiums for critical illness insurance have fallen sharply. Huimin insurance accelerated the expansion speed and has a noticeable substitution effect on traditional products. The integration speed of cross-industry recourse was accelerated，and the brand trend of health management was more prominent. Health insurance premiums are expected to grow at a low rate in 2022. In the long run，policy dividends will still be released，and there is still ample space on the demand side.
