中文摘要：

城市住宅地价不仅受到社会经济发展水平等有形因素的制约,而且还与城市生态环境等无形因素密切相关;而城市绿地系统是影响城市生态环境的重要因素,对住宅地价具有不可忽视的作用。文中以＂中国城市地价动态监测系统＂中51个绿地建设优等区城市为研究对象,以特征价格模型为基础构建模型,测算城市绿地对住宅地价的溢出系数和溢出价值。结果表明：建成区绿化覆盖率、园林绿化建设投资额、人均公共绿地面积、建成区绿地率、建成区环境空气质量优良天数比、城市森林工程造林面积等指标对住宅地价的溢出系数分别为0.0509、0.0090、0.0013、0.0060、0.0041、0.0049;在住宅地价为5000元/m^2的条件下,上述指标每增加1个单位,住宅单位地价就会分别增加254.41、45.14、6.64、30.06、20.25、24.67元。可见,城市绿地很大程度上影响住宅地价水平,研究其溢出效应,可为我国土地出让、转让等价格的完善提供依据,也为开发商的合理投资提供参考。

英文摘要：

The residential land price is not only restricted by the visible factors such as social economic development level,but also closely related to the intangible factors such as urban ecological environment. Urban green space,the important influential factor for urban ecological environment,is very important for the residential land price. The coefficient and value of the spillover effect were calculated by using 51 better greenland construction cities. The results show that the coefficients of green cover,landscaping construction investment,area of common green land average per person,green space rate,good air quality and forestry area are 0. 0509,0. 0090,0. 0013,0. 0060,0. 0041 and 0. 0049 respectively,and their spillover value per unit area are RMB 254. 41、45. 14、6. 64、30. 06、20. 25 and 24. 67 respectively on the condition that the residential land price is RMB 5000 per square meter. Therefore,since the construction of urban green space largely affects the residential land price,the research about the spillover effect provides a basis for the improvement of the remising and transfer price of urban land and a reference on the reasonable investment for developers.
