提要:以2016年北京市五环路范围内的市民实地调研问卷数据为例,采用选择实验法(CEM)对北京市居民对城市林业的支付意愿及行为进行了研究,测算出北京市民对不同城市林业属性状态水平的偏好、各属性的边际价值以及不同组合方案的相对价值,从而间接得出市民对城市林业的支付意愿及额度。研究结果表明:1)市民普遍倾向于较低的城市林业支付费用、较高的绿化覆盖率、较多的公园数量,尤其是较为完善的公园管理;2)教育、收入、家庭人口数以及市民化程度会对其市民效用产生显著影响,而性别、年龄对市民效用的影响并不显著;3)城市林业各个属性的边际价值存在较大差异,其中公园管理的价值最高,达到了146.36元;4)绿化覆盖率不断提高、公园数量不断增加并且有专人进行管理的城市林业组合方案是市民的最佳选择,其每年每人的支付意愿总计达到327.40元。
Abstract: Taking the field survey data of citizens in the Fifth Ring Road in Beijing as an example, this paper studied the willingness and behavior of urban residents to pay for urban forestry in Beijing using CEM, Urban forestry attributes state level preferences, the marginal value of each attribute and the relative value of different combinations of programs, which indirectly leads to the urban public willingness to pay and the amount of urban forestry. The results show that: 1) Citizens tend to pay lower urban forestry costs, higher green coverage and more parks, especially the more perfect park management; 2) education, income, household population and public The degree of the degree will have a significant impact on the effectiveness of its citizens, while the effect of gender and age on the utility of citizens is not significant; 3) The marginal value of various attributes of urban forestry is quite different, of which the value of park management is the highest, reaching 146.36 yuan; 4) Urban greening programs with increasing green coverage, ever-increasing number of parks and manned management are the best choices for the public.
