This study examined the gap between need and provision of community services in China and its association with older adults' life satisfaction over time. Longitudinal data from the Chinese Longitudinal Healthy Longevity Survey from 2008 to 2014 were used (3 waves, N = 16,199). Respondents reported if they needed nine types of community service and if their community provided such service. Growth curve models analyzed whether individual- and/or province-level characteristics predicted the initial level and/or changes of life satisfaction over time. Results indicated the presence of major unmet service needs in China. Available community services were mismatched with older adults' perceived needs. Unmet service needs were associated with decreased life satisfaction at baseline. However, unmet service needs were not associated with changes in life satisfaction over time. Study findings highlighted the urgent need to optimize service design in accordance with older adults' needs, which ultimately could promote older adults' well-being.
