With the rapid pace of population aging,the elderly long-term care,used to be provided by the family system,has turned into a social problem,which must be addressed now.Using data collected from Anhui and Jiangsu,this paper describes the daily living and health status of the elderly,compares the differences of demands for long-term care,and explores factors associated with the demand.Analytical results indicate that region,education difficulty in taking a bath,hemiplegia,pension,daughter or son-in-law care,hukou registration and childless all have a significant impact on long-term care demands.However,their effect varies by development level: they yield a bigger impact on the needs of long-term care service in less development areas than on more developed areas.Based on these findings,a number of policy recommendations on the improvements of long-term care service system have been proposed.
