醫療設施區位具有不同的空間特性，包括：1.就醫便利性，屬於區位正面的「迎毗效果」；
2.設施對環境產生「或多或少」之「鄰避效果」，例如救護車進出產生噪音干擾 (特別在深夜時
刻，居民的感受愈加深刻)、就醫居民產生的交通量造成附近交通擁擠或停車問題、當爆發大規模
傳染病 (例如2003的Severe Acute Respiratory Syndrome, SARS) 時可能被傳染或隔離等情形，對當地居住環境產生潛在風險，導致居民對該設施接受意願的不確定性態度。因此本研究選擇屬醫學中心之「國立成功大學醫學院附設醫院」為研究標的，並以周邊五百公尺範圍之居民為對象，進行問卷調查，運用因素分析，萃取重要因素，歸納大型醫院對於鄰近住宅環境影響的諸要因。結果發現：1.就鄰避效果發現居民較重視大型醫院可能產生之「健康風險」；2.住戶存有藉空間區位的移動以改變醫院設施帶來的負面影響，屬於「距離認知因素」；3.萃取出重要影響因素，可區分為鄰避效果 (住宅環境寧適因素、健康風險因素、住宅環境安全因素) 與迎毗效果 (醫療服務因素)；4.建議可利用隔離綠帶或採適當之距離空間配置，以減輕大型醫院對鄰近住宅環境鄰避效果之影響程度。

Medical facility location considers different spatial characteristics including. 1. Accessibility of
medical service is a positive effect of YIMBY (Yes In My Back Yard); 2. Semi-Obnoxious ex.
ambulance noise (especially in late night), traffic congestion in service hours, SARS (Severe Acute
Respiratory Syndrome) like case quarantined or infected which is negative effect of NIMBY (No In
My Back Yard). This study selected NCKU (National Cheng Kung University) affiliated hospital
(medical center) as target and 500 meters range residents as samples. Then structure questionnaires
were conducted for several effecting factors in terms of housing environment. Therefore factor
analysis was used to extract key factors for explaining hospital like semi-obnoxious facility location
consideration. The result shows: 1. Residents considered more about health risks in terms of NIMBY
effects for medical center. 2. The results show resident intend to change the effects of medical center
by movement. 3. The Factor analysis extracting factors can be classified as NIMYBY effects
(neighborhood amenity, health risk, neighborhood safety) and YIMBY effect (medical service). 4.
Green belt planning is suggested to offer a buffer area for mitigating the NIMBY effects of medical
center.
