作者简介:
摘要:
绿色基础设施的开发利用不仅要考虑经济可行性,即政府或私人投资者的直接成本和收入,还要考虑外部性的社会福利或成本。基于随机抽样调查,针对苏州金鸡湖绿色基础设施的特点,利用条件价值法(Contingent Valuation Method,CVM)对其非使用价值进行货币化评估,并分析了相关影响因素。研究结果表明,苏州金鸡湖保护式开发的平均支付意愿满足理性选择理论,性别和年龄等社会因素对支付意愿有显著影响,整体社会效益明显。研究结论有助于政府和公众从社会效用角度审视绿色基础设施,为政府城市更新、生态恢复等决策的制定提供理论支持。

Assessment of Social Utility of Green Infrastructure Based on the Contingent Valuation Method: Taking Suzhou Jinji Lake Scenic Area as an Example
FU Xi'e
Abstract:
The development and utilization of green infrastructure should not only consider the economic feasibility, that is, the direct cost and income of the government or private investors, but also the social welfare or cost of externalities. Based on the random sampling survey, according to the characteristics of Suzhou Jinji Lake, the nonuse value of Suzhou Jinji Lake Scenic Area is monetarily assessed by using the contingent valuation method (CVM) and the relative factors are analyzed. The results show that the average willingness to pay for the Suzhou Jinji Lake protection development meets the rational choice theory, gender, age and other social factors exert significant influence on the willingness to pay, and the overall social benefit is significant. The conclusions of the study help the government and the public to examine green infrastructure from the perspective of social utility, and provide theoretical support for the decision-making of government, urban renewal and ecological restoration.
Key words:  landscape architecture  green infrastructure  social utility  Contingent Valuation Method  Suzhou Jinji Lake Scenic Area
