隨著電動車技術日新月異，產品更新速度加快亦帶來「過時恐懼」，進而影響消費者的信心與品牌忠誠度。現代消費者除追求產品性能外，更將電動車視為展現個人品味與社會地位的象徵；當產品能傳遞個人價值與社會意義時，將有效提升其購買動機。

本研究旨在探討產品過時恐懼及象徵意義如何影響消費者對電動車採用意願之影響，並進一步分析象徵意義、智能功能與充電基礎設施等因素對電動車採用意願的影響。在技術快速進步與市場持續成長的背景下，消費者行為受到兩股心理動力交織影響：一為對產品迅速被淘汰的焦慮感，二為對電動車所承載象徵意義的期待與認同。當電動車被賦予展現個人形象與社會地位的功能時，其象徵意義可能在過時風險中發揮不同的作用。

本研究透過文獻探討與問卷調查進行，並透過迴歸分析驗證各構面變數之間的關聯性，進一步釐清產品過時恐懼對消費者採用意願的影響機制。研究結果顯示，產品過時恐懼對地位象徵、環保象徵、創新象徵及貨幣價值皆具有顯著正向影響；其中地位象徵與貨幣價值在產品過時恐懼與採用意願之間具完全中介效果。此外，地位象徵、貨幣價值、智能功能與充電基礎設施皆對電動車採用意願產生顯著正向影響。
