在各國地震災害頻傳的情況下，政府災前預防行為的推行配合民眾落實成為減少未來災害發生造成嚴重損失的重要關鍵，如何與民眾進行溝通執行地震預防政策的過程中，地震災害風險知覺之研究即成為擬定風險溝通策略下的參考基礎，亦為來各國長久研究的核心所在。隨著國外相關研究逐漸成熟，提出不同個人社經屬性對於地震風險知覺與其相關變數有所差異，其中年齡又被視為最具關鍵且影響決策行為的重要因素之一。年齡對於都市規劃的影響雖為近期所著重的課題，但目前於此議題上卻尚未成為深入探討之標的，國內研究探討地震災害風險之研究更為少數。爰此，本研究將運用年齡進行分類下(包含青壯年、中年與高齡者)，分別探討各年齡族群間地震災害風險知覺與個人社經屬性變數之關係，以地震高風險地區臺南市永康區為實證地區，並結合國外既有研究成果進行討論，解析不同年齡族群對於地震風險知覺的差異性。根據本文研究成果指出：其一，各別年齡族群對不同的地震災害風險知覺具差異性；其二，個人社經屬性對地震風險知覺的關係性上於對個別年齡族群上並非存在一致性，有別於過去國外研究所歸納之成果；其三，地震災害風險知覺與住宅補強行為的關係性上僅高齡族群具統計顯著性。藉由本文之研究成果，可做為未來執行住宅結構補強行為政策推動與溝通之參考。

The implementation of seismic risk reduction mitigation policies by governments and residences plays a critical role in reducing earthquake losses when the global frequency of high magnitude earthquakes increasing in recent years. The study on seismic risk perception is the importance of long-term issues, contributing to develop strategies for effective risk communication in the process of implementing earthquake disaster mitigation policies. Global research in this topic developed maturely shows the unique relationships between seismic risk perception and various personal and social-economic variables. In these serial research results, “Age” is seemed as one of the most influential variables in risk perception and mitigation behavior and is also the key topic in recent urban planning research. However, the association of each age group and risk perception expresses its disappointment with the lack of discussion, and domestic research shows restricted results in seismic risk perception. In sum, this study focuses on discussing the relationships between seismic risk perception and personal and social-economic variables in each age group with a Case study in Yongkang District City of Tainan. According to the research results, three main findings are shown as follow: (1) differences in risk perception among each age group are shown; (2) the relationships between seismic risk perception and personal and social-economic variables, differing from the past research findings, are inconsistent in each age group; (3) the statistically significant relationship between seismic risk perception and residential structural reinforcement is only shown in the Elderly. The results in this study could be referred as the implementation and propaganda of seismic mitigation policies.
