城市生物多样性保护的支付意愿及其影响因素——以成都市温江区为例

Willingness- to- pay for biodiversity conservation in urban ecosystem and its influencing factors: taking Wenjiang District of Chengdou City for exmaple

基于间接效用函数理论,运用支付卡式条件价值评估法测算了成都市温江区城市生态系统生物多样性保护的支付意愿,并利用二元选择模型和多元有序选择模型分析了影响支付意愿与支付水平的主要因素。结果显示:调查样本平均支付意愿率和最高平均支付意愿值较高,分别为63.1%和120元/年;居民年均收入对支付意愿和支付数量具有显著正影响,而居民的支付意愿和支付数量均存在距离衰减性;与对城市生物多样性缺乏认知、保护态度消极的受访者相比,认知程度高、保护态度积极的受访者的支付意愿均显著提高,但认知和态度这两个变量对支付数量的影响不显著。

Based on the theory of indirect utility function and survey data,the residents＇ WTP for biodiversity protection of urban ecosystem in Wenjiang district of Chengdu City are measured by using the Payment Card Contingent Valuation Method,and then its influencing factors are comparatively overall analyzed by using the Logit and Oprobit Models. Results show that： the probability and amount of the residents ＇ WTP are high,63. 1% and 120 yuan / year respectively; the probability and amount of the residents＇ WTP is high among people with higher income,while it is lower with the aggrandizing of distance; Compared with the respondents who lack of cognition to biodiversity protection,or with the negative protection attitude,the other respondents which have higher cognition or with strong protection attitude have a higher probability of WTP,but the influence of these variables on the amount of residents＇ WTP is not significant. Finally,the biodiversity conservation of urban ecosystem in the future are to be prospected and discussed.
