【摘要】：运用Hedonic法评估自然资源的经济价值是近期国外研究的热点之一。近年来,国内基于Hedonic法的自然资源外部性评估的研究也相继出现且多采用标准最小二乘法回归。本文收集513个上海市中心城区二手房房价及其特征数据,采用空间自回归的Hedonic法评估城市开放空间的经济价值,结果显示:1城市开放空间对二手房房价的影响是显著的,其中城市绿地的外部性在房价呈现显著的正相关,河流的外部性对房价的影响是非线性的;2空间干扰的存在会造成标准最小二乘法回归的标准回归模型评估有偏差,对于存在空间自相关的研究数据,应选用合适的空间自回归模型进行评估。研究结果为淡水生态系统的恢复和城市绿地的规划提供新的方向,为城市开放空间管理和决策修订给予政策指导。
[Abstract]:Using Hedonic method to evaluate the economic value of natural resources is one of the hotspots in recent foreign research. In recent years, the study of natural resource externality evaluation based on Hedonic method has also appeared one after another, and the standard least square regression has been used more and more. In this paper, the data of second-hand housing prices and their characteristics in 513 central urban areas of Shanghai are collected, and the economic value of urban open space is evaluated by spatial autoregressive Hedonic method. The results show that: 1the influence of urban open space on second-hand housing prices is significant; The externality of urban green space has a significant positive correlation with house price, and the influence of river externality on house price is non-linear. (2) the existence of spatial interference will cause deviation in the evaluation of the standard regression model of standard least square regression. For the research data with spatial autocorrelation, appropriate spatial autoregressive model should be chosen to evaluate it. The results provide a new direction for freshwater ecosystem restoration and urban green space planning, and provide policy guidance for urban open space management and decision-making revision.
