以四川温江为例,基于选择实验法采用Mixed Logit模型,对温江居民生态系统服务支付意愿的影响因素进行定量化研究。研究表明,月收入对温江居民的影响在较低支付价格意愿水平上不显著,而在较高支付价格意愿水平上表现为收入越高者支付意愿越强;温江居民年龄越长者、受教育水平越高者、家附近公园个数越多者、对温江感情越深厚者、对环保支持力度越大者、对地方政府的信任程度越高者,表现出的支付意愿越强。此外,还对温江城镇和农村居民支付意愿影响因素进行了对比分析。研究拓展了选择实验法应用领域,为区域城市生态环境改善和经济社会协调发展提供决策依据。
Taking Wenjiang in Sichuan Province as an example, the influencing factors of residents 'WTP for ecosys- tem services are analyzed. The Mixed Logit model is used in this paper based on the Choice Experiments method. Research shows that, income doesn' t relate to residents' WTP at the lower price level, but at the higher price level residents' WTP will be positive when income increases. And the older, the higher education level, the more num- ber of parks near home, the deeper feeling to hometown, the more support for environmental protection, and the more trust to local government the residents are, the more willingness to pay for ecosystem services. In addition, the influencing factors of urban and rural residents' WTP are compared in this paper. And this study expands the appli- cation field of the choice experiment method and provides the theoretical basis for local policy-makers to achieve coordinated development of environment and resources and social economy.
