| Healthy and better life of the elderly is an important part of people’s better life in the new era,and it is also the core value goal of actively coping with aging.Under the background of rapid aging and aging of population,old-age security expenditure is facing huge pressure.It is urgent to speed up the optimization of the allocation of limited pension resources,improve the use efficiency and efficiency,and the premise of optimizing the allocation of pension resources is to clarify the health performance of different projects of old-age security expenditure.The existing researches pay more attention to the health performance of individual project of old-age security expenditure,mainly the impact of medical insurance on health and medical expenditure,and lack the health performance comparison of each project system of old-age security expenditure.Based on this,this paper puts forward the theoretical framework of research on the basis of Grossman’s health capital theory and Anderson’s health service utilization model.Using CLHLS2014 data,a structural equation model is established to compare and analyze the health performance and realization path of old-age security expenditure(pension,care and medical care).The results show that: first,there are significant differences in health performance of old-age security expenditure.Pension significantly improves the subjective health of the elderly,while subjective health significantly improves physical health.To a certain extent,care expenditure can improve the health of the elderly.Medical insurance reimbursement has a negative correlation with the subjective health and physical health of the elderly.In general,the health performance relationship of old-age security expenditure: pension > care expenditure > medical insurance.Secondly,each item of old-age security expenditure has economic performance,and economic performance has intermediary effect in the path of health performance of old-age security expenditure.There is an inverted U-shaped relationship between pension and out of Pocket Medical Expenditure,and a U-shaped relationship between care expenditure,medical insurance reimbursement and out of pocket medical expenditure.It shows that higher level of pension income,early intervention of care expenditure and medical insurance have economic performance.At the same time,there is a significant negative correlation between the self paid medical expenditure of the elderly and subjective health,physical health,which indicates that higher level of pension income,early intervention of care expenditure and medical insurance can significantly reduce the self paid medical expenditure of the elderly,and generate health performance through economic performance.Economic performance has intermediary effect,and there are multiple complex intermediary transmission paths,which to some extent explains the realization path of health performance of old-age security expenditure.Third,each item of old-age security expenditure also has internal logical connection.The elderly with high pension income are more able to buy care services and improve medical access,so they can increase the expenditure of care and medical insurance reimbursement.The expenditure of care and medical insurance reimbursement are negatively correlated.By adding more control variables and changing samples in different periods,the robustness of the results is tested.The findings of this paper provide a new way to improve the practice of old-age security policy.To cope with the huge pressure of old-age security expenditure under the background of aging,we should be based on the internal logic of maintenance medicine and its health performance mechanism.In the future,the health security of the elderly in China should gradually turn to a better life security system relying on pension from the treatment of diseases as the center.The internal logic of maintenance medicine can be followed to control medical expenditure,increase resource investment of pension protection,and pay attention to front-end protection.Based on this,the paper puts forward policy suggestions,including promoting the development of the combination of medical care and maintenance,promoting the coordinated linkage of maintenance and medical care,gradually turning to health and good life security,optimizing the pension insurance treatment adjustment mechanism,deepening the compensation and payment mode of medical insurance,and establishing the long-term care insurance system as soon as possible. |
