随着居民生活质量的提高和环保意识的增强,居民对环境舒适的支付意愿不断提高。居住环境的价值评估研究受到关注,但对其作用时间和空间影响程度差异的量化研究明显不足。本文以上海市黄兴公园绿地为例,综合运用市场比较法、特征定价法和多元回归分析等方法,并引入加权距离,从时间和空间两个层面分析黄兴公园绿地对周边住宅价格的影响效应,结果表明:黄兴公园绿地所带来的住宅价格增值效应既具有时间上的差异性,又与加权距离存在着显著的二次函数关系,随着距离增加其增值幅度呈下降趋势;其影响效应与加权距离存在着显著的三次函数关系,最大影响半径为1.59km,最强影响区位为0.29km。
Along with the improvement of people's living standard and the enhancement of consciousness about environmental protection,the willing to pay(WTP) for environmental amenity has increased day by day.The research on the valuation of living environment has been paid more attentions.However,there are only the qualitative impact studies,but lack of the quantitative impact analysis from the temporal and spatial views.Moreover,the existing studies have offered little theoretical support for urban policy decision-makings.It is these shortcomings that have brought out the inequality in the distribution of real estate appreciation,a waste of location resources as well as the fault of urban land planning and urban decision-makings.In the present study the authors apply hedonic pricing method,market comparative method and spatial proliferation effect theory,bring in the weighted distance,and analyze the temporal-spatial impact effects of large-scale park on the surrounding residential prices exemplified by the Huangxing Park in Shanghai city,and put forward its metric model of value spill over.The research results show that the appreciation of housing prices varies at temporal and spatial scales,displays significant conic curve relation with weighted distance and decreases gradually with increased weighted distance.The appreciation in north-south direction is more than that in east-west direction,and its impact manifests significant cubic curve relation with weighted distance.Its maximum impact radius is 1.59 km,and the strongest impact location is 0.29 km.Finally,some suggestions are proposed so as to determine rationally the location of residential development and to distribute properly land appreciation earnings.
