Abstract
Due to the increase of housing poor and the entire transition of economic and social condition, the amendment of Public Housing Law and its enforcement order has been tried and partly realized. However, discussions about the present public housing rent system based on both benefit and ability to pay has been rarely heard until now, even though it seems to be the core of the system. The paper firstly clarifies problems and proposes a preferable alternative for the present calculation method of public housing rent, and then verifies the effectiveness of the proposed measure by analyzing drawing ratios of public houses in Kyoto city.
