Abstract: Objective To understand the willingness and influencing factors of the pension model choice in the outer suburbs since the pilot implementation of the long-term care insurance policy in Shanghai, so as to provide basis for improving the elderly care service security system in Shanghai. Methods Based on Anderson model, a self-designed questionnaire was used to investigate the willingness of the pension model choice in the outer suburbs, and multiple Logistic regression analysis method was used to analyze the factors that affect the choice of elderly in the outer suburbs. Results Of the 955 elderly, 77.2% chose home-based care, 13.2% were willing to accept community-based care, and 9.6% chose institutional care. Logistic regression analysis showed that the elderly with junior high school education （OR=4.254）, who agreed with “living in an elderly care institution shows that their children are unfilial and feel ashamed when living in an elderly care institution” （OR=13.062）, who did not know much about the unified needs assessment of elderly care in Shanghai （OR=5.214）, and who were in good health （OR=7.550） might choose home-based care more than institutional care. The elderly with basic endowment insurance for urban employees （OR=0.115） and had two children （OR=0.310） might choose home-based care less than institutional care. Conclusion Shanghai should strengthen the publicity and implementation of elderly care service policies such as long-term care insurance and unified needs assessment for elderly care, change the concept of elderly care for the elderly, and improve the social elderly service capabilities in the outer suburbs.
