The construction of the public rental housing in recent years has made significant progress, but the definition of the security objects, mainly relies on the perceptual experience of the local government or simply the "tap a head" behavior, resulting in the coverage of the security objects of the housing lacking the theoretical and technical support, so that the distribution of the social public resources is unfair. The paper takes Ningbo as an example, and proposes the countermeasures and suggestions to improve the coverage of the security objects of the public rental housing. Break the binary structures of the urban and rural areas, and promote the overall planning of the urban and rural areas of the security objects of the public rental housing. Integrate the resources of the two levels of the municipal and district levels, and promote the effective management of the security objects of the public rental housing. Improve the access accounting standards of the income, and ensure that all the security objects of the public rental housing entitled to basic living allowances are now basically receiving them. Establish and improve the screening mechanisms, and realize the dynamic recognition of the security objects of the public rental housing. The proposal of the public rental housing is to further expand the coverage of the housing security, and more widely solve the problem of the difficult housing of the "sandwich class" crowd in the cities. The features that the coverage of the people is wide, and the subsidy policies are flexible and diversified, and the operation is relatively simple and transparent, which is suitable for the establishment of the exit mechanism make it become the first choice to improve the housing security systems in all the areas. We should carry out the investigations and researches on the coverage of the security objects of the public rental housing in Ningbo, and pinpoint the clear definition and the scale calculating of the security target population of the public rental housing, help the governments reasonably arrange the construction plans of the public rental housing, ensure the relative fairness of the policies, and further improve the scientific and efficient housing security system.
