中文摘要：

通过收集整理有关大连市经济适用房和普通商品房信息,采用spss、mapinfo、surfer等软件研究经济适用房空间分布,绘制经适房位置房价等值线图、经适房距城市中心＂相对＂距离变化等值线图,结果表明大连市经济适用房以6 500元等值线为界分为普通经济适用房、单位集资建房两种类型,受成本因素、环境因素、通勤因素、基础设施和公共设施4种首要因素影响;运用AMM模型分析大连市各个经济适用房楼盘福利损失状况,发现单位集资建房均不存在福利损失而普通经济适用房除石门山经济适用房外均存在福利损失。针对存在福利损失的经济适用房楼盘,依据经济适用房距城市中心＂相对＂距离变化规律得出每个楼盘福利损失年限。
