Abstract: In the process of the government's purchasing in-home elderly services， to improve the beneficiaries' satisfaction is an important task. Therefore， it is necessary to understand what will affect the beneficiaries' satisfaction. Based on the literature review， four influential factors of satisfaction were summed up， including quality， fairness， efficiency， and administrative cost， and theoretical assumptions were made on this basis. SPSS 20.0 was used to give the correlation analysis and multiple regression analysis based on the survey data obtained from Hefei， Yangzhou， Nanjing and Xiamen. The results showed that there is a positive correlation between satisfaction and quality or efficiency， and there is a negative correlation between satisfaction and administrative cost. Finally， based on the data results， it was proposed to construct a good interactive environment to improve the conversion ratio of quality， efficiency， administrative cost to satisfaction， optimize the efficiency to help integrate the influential factors of satisfaction， improve the quality to enrich the core of satisfaction and save the administrative cost to achieve a sustainable growth of satisfaction.

Key words: government's service purchase, in-home elderly service, satisfaction
