Relational values help explain green infrastructure preferences: The case of managing crane habitat in Hokkaido, Japan

The initial purpose of our study was to understand preferences of stakeholders on green infrastructure for flood control using a discrete choice experiment. However, the results of our study included unexpected findings. According to the utility theory of economics, an inexpensive green infrastructure scenario should have been chosen under ceteris paribus conditions, but our results differed from this expectation. Inconsistent results like ours are often interpreted as indicating bias and/or questionnaire design issues. However, our results can be interpreted using relational values. We studied green infrastructure in a large-scale flood control basin in Naganuma, a town in the Hokkaido prefecture in Northern Japan. We conducted a discrete choice experiment with town residents as stakeholders of the green infrastructure. Through the examination of choice and membership parameters of our results, we interpreted that individual identity and place attachment, which are types of re...本研究最初的研究目的为通过离散选择实验（Discrete Choice Experiment），探究利益相关者对防洪型绿色基础设施（green infrastructure）的偏好。然而，本研究得到了意料之外的结果。根据经济学效用理论（utility theory），在其他条件不变的前提下，成本低廉的绿色基础设施情景方案理应被选中，但本研究结果与这一预期相悖。 类似本研究的相悖结果通常会被解读为存在偏差或问卷设计缺陷，但本研究的结果可通过关系价值观（relational values）进行阐释。 我们以日本北部北海道地区的长沼町（Naganuma）大型防洪流域为研究对象，以当地居民作为绿色基础设施的利益相关者开展了离散选择实验。 通过对本研究结果中的选择参数与归属参数进行分析，我们认为个体认同与地方依恋属于一类……
