Therefore， the government should foster multiple collaborative supply subjects of the home-based care service for the elderly， stimulate rural communities capital to participate in the collaborative supply of the home-based care service for the elderly， promote the governments guidance of and multiple participation in the supply subjects collaboration， and construct the multiple risk response mechanism among the collaborative supply subjects of the home-based care service for the elderly.

Key words: rural community, home-based care service for the elderly, collaborative supply
