The main contents are as follows: In chapter 1, systematic conclusions of intension and characteristic of sustainabledevelopment of real estate industry are made after the review of home and foreign research achievements; Chapter 2 analyzes status quo and trait of Chinese real estate industry in 2005, from views of investment, exploitation and sale, three parts of real estate industry, with the help of massive graphs, as well as elaborates main problems existing in real estate market; In chapter 3, the gambling thought is used to divide the developing process of Chinese real estate market into three phases, according to the change of main market participators and their behaviors; Finally, in chapter 4 and 5, a system with 72 indices in research on sustainable development of real estate industry in china is established, and theories of Catastrophe, Cosines Vector Included Angle, Entropy and CRITIC are applied to appraise the current situation of sustainable development of real estate industry in 31 provinces and cities in 2004, then the consistency test of appraisal results is carried out by Kendalls Coefficient of Concordance and Spearman Correlation Coefficient.

本文的主要内容如下：第一章在查阅大量国内外有关可持续发展理论、房地产业有关研究文献的基础上，评介了有关理论概念，并对房地产业可持续发展的内涵进行归纳、总结；第二章从房地产投资、开发和销售三个环节入手，结合大量图表，分析2005年中国房地产业的发展状况和特点，揭示我国房地产市场存在的主要问题；第三章利用博弈思想，根据市场参与主体及其行为的变化，将中国房地产市场的发展过程分为三个阶段；第四、五章构建了一个由72个指标构成的房地业可持续发展指标体系，利用突变评判法、向量夹角余弦法、熵值法和CRITIC法对2004年全国31个省市的房地产业可持续发展状况进行评价，并运用肯德尔和谐系数和斯皮尔曼等级相关系数对评价结果进行一致性检验。
