The paradox matter-element extension theory is fit for the contradictive study, and consistent with the sustainable development of the real estate industry in terms of research subject, logic theory, and variability. On basis of these, this Study establishes extension-theory-based evaluation index system for sustainable development of real estate industry, in which the indices are categorized into five groups: economy and finance, social equality, ecological environment, resources utilization, and government management.
