With the gradual deepening of the aging process in China，the characteristics including empty nesting，aging and chronic diseases have become increasingly prominent. The pressure of pension issues is becoming increasingly severe. The demand for elderly care is growing, yet its supply is seriously insufficient. In order to explore the profound structural contradiction of the imbalance between the demand and supply of pensions，we conducted a questionnaire on urban residents’demand for elderly care in Jiangsu Province to clarify the current situation of their elderly care needs and the variation of needs between different groups. In order to clarify the indicators and internal causes of supply - demand imbalance, we also combined the results with the current state of pension supply in Jiangsu Province to conduct demand-oriented research on the supplydemand balance of pension services. On this basis, we propose suggestions such as updating the concept of elderly care supply, improving the level of elderly care supply and the diversity of elderly care services, promoting the development of the community home-based elderly care model，establishing a standardized elderly care community，and reforming the elderly oriented design of communities and families.
