The main findings of the empirical analysis include: 1 The decisions concern the choices of auto ownership, mode to work, and auto use were made simultaneously and interrelatedly. 2 The decline in correlation between the choices of auto ownership and use as the number of vehicle increase indicated that to own multi-vehicles in not necessary due to the demand for auto use. 3 Both price elasticity and income elasticity for auto ownership are low. This evidence implies that auto has become a kind of necessity for household. Therefore, the effect of decreasing the tendency of auto growth by means of increasing the cost of owning auto would not be significant. The price elasticities of auto use are between -0.48 and -0.78. 4 There are same underlying factors influencing auto ownership, mode to work, and auto use including: parking time at residential location, accessibilities to work location by auto and transit, auto use unit cost, and the percentage of auto use for work. These factors indicate a direction for the formatting of future automobile policies.

本研究以台湾地区之家户个体资料从事实证分析，实证分析之主要结论如下：1小汽车持有数量、工作者工作运具选择、与小汽车使用量等选择间确有相关与联立性存在；2小汽车持有数量选择与小汽车使用量选择间之相关性会随小汽车持有数量的增加而降低，显示选择持有多部小汽车并非完全基於小汽车使用之需要；3小汽车持有之价格弹性与所得弹性均偏低，显示小汽车已成为民生必需品，欲以提高小汽车持有成本之价格手段来抑制小汽车持有，并无法竟其功，小汽车使用需求之价格弹性则在-0.48与-0.78间；4影响小汽车持有数量、工作者工作运具、与小汽车使用量等选择主要之相关或共同因素包括：家户附近停车状况、私人运具与大众运输工具之工作可及性、小汽车单位使用成本、与小汽车工作使用比率等，以上这些影响因素可为日后小汽车相关政策的研拟提供一方向。
