Objective： To analyze the interest relationship between different subjects involved in the process of supporting the left⁃behind elderly in rural areas，and to provide strategic suggestions for improving the reasonable allocation of rural supporting resources. Methods： Analytic hierarchy process（AHP） and graph model for conflict resolution（GMCR） were used to construct the GMCR⁃AHP model of the interest demands of the government，pension institutions，families and the elderly，analyze and optimize the conflicts among the relevant subjects in the current allocation of pension resources for the left⁃behind elderly in rural areas，and explore the global stable state of the interest balance of each subject. Results： Through conflict analysis，the equilibrium solution is YNYNNYNY，that is，the government improves supporting policies and leads the old⁃age care work.Old-age care institutions strive for more government subsidies to expand the range of old⁃age care services；children in the family can not take care of the elderly，choose institutions for the aged；the elderly themselves are eager to get more government economic policy support to ease the pressure of family pension. Conclusions： In order to alleviate the conflict of interests of various subjects under the dilemma of supply and demand of rural pension resources and rationally allocate rural pension resources，the government should lead the cooperative governance of multiple subjects and increase the investment in rural pension industry.Pension institutions should keep up with the change of policy direction and develop the service mode of combining medical and nursing care；Families take the health of the elderly as the first priority and support institutions for the left⁃behind elderly.At the same time，the old people themselves change the traditional pension concept and actively participate in the pension mode under the new situation.

Objective： The aim of this study is to explore the preferences of disabled elderly people for home-based medical care services in Beijing，with a view to enhancing the utilization rate of said services. Methods： Utilizing a discrete choice experimental design and aided by a self⁃designed questionnaire，convenient sampling was conducted for face⁃to⁃face surveys among 253 elderly individuals and their caregivers in two Beijing communities.Preferences for home⁃based medical care services among the disabled elderly were determined using a mixed logit model. Results： Significant influences（<0.05） were found on preferences for home⁃based care among the disabled elderly⁃aspects like payment costs，institutional nature，appointment method，and service content all playing a part.The order of attributes based on willingness to pay are：institutional nature，appointment method，service content and service decisions.Factors including gender，education level，disability degree，income，number of children，and marital status all affect the home care service preferences of disabled elderly individuals. Conclusion： Home⁃based disabled elderly individuals prefer lower-cost services from public institutions that can be scheduled online or offline.They prefer not to receive in-home health management services and show no preference towards service decisions or caregiver experience.These findings can be used to cater services better to the preferences and specific characteristics of home-based disabled elderly individuals.
