Replication Data for: Public Service Motivation and Not-In-My-Backyard: The Case of High-Level Radioactive Waste Disposal Sites in Japan

This study investigated the association between public service motivation (PSM) and the not-in-my-backyard (NIMBY) reaction by the public that often blocks important projects. A conjoint experiment was conducted using the scenario of hypothetical plans for the construction of a high-level radioactive waste disposal site, one of the most noxious NIMBY facilities. The results showed that overall PSM (the full scale) had no association with the public’s willingness to accept such facilities. Still, we observed significant positive correlations for the PSM dimensions of attraction to public service and self-sacrifice, and a significant negative correlation with the PSM dimension of compassion. As expected, some dimensions of PSM strengthened (moderated) the positive effect of policy attributes on acceptance. Contrary to our prediction that PSM attenuates the relationship between distance and acceptance, overall PSM, commitment to public values, and compassion amplified the relationship. Together, these findings suggest the need to promote research considering the multifaceted nature of PSM in NIMBY problems.

本研究探讨了公共服务动机（Public Service Motivation, PSM）与公众常阻碍重要项目的邻避（Not-In-My-Backyard, NIMBY）抵制行为之间的关联。本研究以高放射性废物处置场——一类极具争议的邻避设施——的假设建设规划方案为情境，开展了联合实验（conjoint experiment）。研究结果显示，整体公共服务动机（全量表）与公众接受此类设施的意愿并无显著关联；不过细分维度来看，公共服务动机中的公共服务吸引力（attraction to public service）与自我牺牲（self-sacrifice）两个维度与接受意愿呈显著正相关，而同情心（compassion）维度则与接受意愿呈显著负相关。正如预期，部分公共服务动机维度会强化政策属性对设施接受意愿的正向影响，即发挥调节作用。但与我们的预测相悖的是，我们原本假设公共服务动机能够削弱距离与接受意愿之间的关联，实际结果却显示，整体公共服务动机、公共价值承诺（commitment to public values）以及同情心维度反而增强了二者间的关联。综上，本研究结果提示，未来针对邻避问题的研究需充分考量公共服务动机的多维度特性。
