摘要

本研究估计了巴希尔达尔市当地环境设施的经济价值,巴希尔达尔市是埃塞俄比亚的一个旅游景点。本研究采用选择实验评价方法,对塔纳湖、城市公园、棕榈树和街道清洁度四个环境设施属性进行了识别。本研究采用概率多阶段随机抽样技术。该分析基于对巴希尔达尔市家庭调查的原始数据。该研究为每个受访者提供了九个选择;每个选择集有三个选项,包括现状选项。本研究采用混合logit模型。结果表明,所有改进的属性水平均有正信号,且具有统计学意义。正如预期的那样,与经济学理论一致,货币成本具有负的迹象和显著性。混合logit模型表明,在某些属性层次上存在偏好异质性。根据调查结果,研究建议市政当局和有关机构预期实施假设的政策方案,以改善环境。

Economic Valuation of Local Environmental Amenities: A Case Study of Bahir Dar City, Amhara Regional State, Ethiopia
This study estimates the economic value of local environmental amenities in Bahir Dar city which is one of the tourist attraction sites in Ethiopia. The study employed choice experiment valuation method by identifying four environmental amenities attributes (Lake Tana, urban park, palm tree and street cleanliness). The study used probability multi-stage random sampling technique. The analysis was based on primary data surveyed from households in Bahir Dar city. The study presented nine choices set for each respondent; each choice set has three alternatives including the status quo option. The study employed a mixed logit model. The result showed that all improved attribute levels have positive signs and statistically significant. As expected and consistent with economic theory the monetary cost has negative signs and significant. The mixed logit model showed that there is preference heterogeneity in some attribute levels. Based on the finding, the study recommends that the city administration and the concerned body expected to implement the hypothetical policy scenario so as to improve environmental amenity.
