Advances in medical technology and the improvement in living standards have increased the average life expectancy of Taiwanese people. However, declining birth rates have caused a rise in Taiwan’s elderly population, and Taiwan is gradually moving towards a hyper-aged society. Additionally, the number of disabled elderly people and those with chronic diseases also continues to increase, but changes in traditional family structures have led to a decline in elderly care resources. These factors all highlight the urgency of long-term care now and in the future, as well as the importance of preparing for long-term care needs in the future. Currently, the government and insurance companies are actively promoting long-term care insurance and establishing related systems. However, the penetration rate of long-term care insurance is only about 2%, indicating that stronger promotion and better design of long-term care systems is needed. In this study, we used quantitative analysis to investigate the Taiwanese public’s needs and willingness to purchase long-term care insurance, in hopes of providing improvement suggestions for insurance companies and the government.
