摘　　要：为估计城市公共服务的价值,并评价城市公共政策,建立了一种空间计量经济学模型。该模型考虑了空间自相关与空间滞后因素,修正了传统特征价格模型(即Hedonic方法)中由于空间相关性造成的影响。利用北京的住宅市场微观交易数据,进行了数据检验,将估计结果与传统的Hedonic方法的结果进行了对比。结果表明:空间相关性显著存在于住宅市场中;不考虑空间作用的模型将会略微高估城市公共服务的价值;该估计结果比用传统的Hedonic方法的结果更可靠。A spatial econometric model was developed to estimate the value of local public services to formulate local public policy.The model includes spatial dependence and spatial lag factors to modify the bias of the traditional Hedonic method caused by spatial dependence.The estimates were correlated using reliable empirical data for micro-transaction in the housing market for Beijing and compared with results using the normal Hedonic model.The results show that a spatial correlation effect exists in the housing market and that the local public service price is not overestimated much by models not considering the spatial dependence.Thus,the model gives more reliable results than the traditional Hedonic method.
