| dc.description.abstract | This paper aims to investigate the relationship between the self-paid amount of medical materials and the scale of medical institutions, market competition in each county, and the proportion of the elderly population with a self-paid amount of artificial intraocular lenses from each medical institution.
The empirical results show that after controlling for the fixed effect of medical materials, the regional average household annual income has a significant positive effect on the self-pay amount, which means the region with higher income are more willing to use the intraocular lenses with functions and quality that meet their needs. At the hospital level, the self-pay amount in descending order is clinics, regional hospitals, district hospitals, and medical centers. But at the hospital level and hospital group, the self-pay amount in descending order is medical centers, district hospitals, regional hospitals, and clinics. The proportion of the elderly population and the increased rate of the elderly population have no significant effect on the self-pay amount because the cataract patients tend to be younger due to the long-term use of 3C products. The self-pay amount of public hospitals is lower than private hospitals and nonprofit hospitals, and there is no significant effect between private hospitals and nonprofit hospitals. | en_US |
