臺灣男女性平均死亡年齡之空間分析

Abstract

本研究透過空間分析方法，探索臺灣男性與女性平均死亡年齡之空間分佈現象，主要目的在於對臺灣男女性平均死亡年齡存在地區落差與空間聚集現象進行解釋說明。本研究透過以往文獻分析，將影響男女性平均死亡年齡的因素分為四個概念：經社背景因素、醫療與資源因素、環境因素與空間因素，再從各個概念中歸納出對男女性平均死亡年齡可能有影響的變數。透過迴歸分析後發現，男女性平均死亡年齡受經社背景因素的影響最大；醫療與資源因素以及環境因素對男女性平均死亡影響呈現無顯著關聯；加入空間因素的分析，發現男女性平均死亡年齡的空間自相關現象並非鄰近效應所造成，意即鄰近地區之間的平均死亡年齡不會產生彼此相互影響的現象。

Through spatial analysis methods, this study explores the spatial distribution of male and female average age of death in Taiwan, and tries to explain what factors affect male and female average age of death having regional gap. This study uses previous literature and research to classify the possible factors which interfere spatial distribution into four categories: eco-social backgrounds, medical and resources factors, environmental factors and spatial factors, and then summarizes the possible variables with significant effects to male and female average age of death from the categories. After regression analysis, this study finds that the variables of eco-social backgrounds have greatest impact on male and female average age of death. Relatively, medical and resources factors and environmental factors show no significant association. Adding variables of spatial factors into regression analysis, this study also discovers that the spatial autocorrelation of male and female average age of death are not caused from neighborhood effect, which means the average age of death between neighbor regions do not affect each other.
