中文摘要 |
宜蘭縣地處東部區域,往年因聯外交通不便、一級產業居多及就業機會稀少等因素,導致縣內之人口外移及人口呈遞減現象,但北宜高速公路之開通將大幅提升其對外交通之可及性,人口是否仍呈負成長值得加以探討。十二市鎮鄉各人口之年增減量如何變動?宜蘭縣是否已進入高齡化社會?此等人口特性變化議題及未來發展趨勢值得加以釐清。 本研究以宜蘭縣近年來之人口資料為基礎,分析宜蘭縣人口之結構特性,結果發現宜蘭縣已進入高齡化社會,且宜蘭縣十二市鎮鄉近年來僅宜蘭市與羅東鎮之人口呈現正成長,其餘十鎮鄉之人口除冬山鄉近二年外幾皆呈衰減現象。本研究進而藉由灰預測GM(1,1)模式推估宜蘭縣未來可能之人口,以提供政府部門擬議人口發展政策之參考。 |
