有鑑於內政部警政署十餘年來的統計資料，酒後駕車高居A1交通事故的肇事因素排名前一二名，本研究運用內政部警政署2003-2013年A1、A2類交通事故調查報告表，探討經濟景氣對於台灣本島酒駕事故影響的因素，如失業率、所得及酒類消費量等，並深入探討經濟景氣對於酒駕死傷及酒駕駕駛人的影響。 依追蹤資料迴歸模型進行實證研究分析發現，失業率的增加，明顯增加交通事故的發生；對於酒駕而言，男女失業率對於酒駕事故則有不同的影響，仍可看出經濟景氣確實影響酒駕事故的發生，有其重要關聯性。 除了失業率外，影響酒駕事故的發生另一個大又直接的因素，即是高濃度酒類消費量，因著男性為主要喝酒族群，因此顯著正向影響酒駕事故的發生。 因此，本研究針對失業率及高濃度酒類消費提出建議，供政府相關單位參考用，以有效降低酒駕事故的發生，減少家庭悲劇的發生。 ;According to National Police Agency statistics which have been obtained for more than ten years, it is drunk driving that mainly causes A1 traffic accidents (A1 fatal).
