It is found tha t vacant ratio of samples in Guangzhou accounted for 20.94%, which is relativel y high. The authors argue that real estate industry of Guangzhou has made rapid progress, at the same time, people should not overlook the vacant commercial hou sing. It will benefit the sustainable development of the real estate industry of Guangzhou to carry out effective measures and actively to make use of present v acant housing.展开更多

How to evaluate the multi-functional nature of housing is very useful in both theory and in application, yet it is often ignored in China. This paper introduces an approach to estimate the multicriteria function of housing using multiattribute utility theory (MAUT) based on consumers’ ordinal multicriteria preferences as determined via questionnaires. When compared with the classic framework in which MAUT is applied, this approach needs less prior information and subjective comparisons and thus can allay many of the operational difficulties involved in assessment. Some potential applications to the China housing market are also discussed.展开更多
