摘要

本研究藉由問卷調查方式，瞭解政府部門在推動油氣雙燃料車之相關執行政策與補助措施。由研究調查結果顯示，約有36.2%受訪者認為補助金額太少，且經濟誘因不足，有21.3%受訪者認為申請程序繁瑣；另對於政府推動新購或換購低污染車輛之優惠措施，希望以補助購車款或改裝費用者較高，約占42.2%，減免燃料費或停車費占34.6%次之，認為以補貼油氣價差者占21.5%。
使用油氣雙燃料車較汽油車以經濟效益分析來看，每年可節省約50,829.1元，換算成汽油燃料，每年約可節省1,585.4公升之95無鉛汽油。但目前民眾對於低污染車輛除新購或換購之補助經費外，仍需自行負擔一定比率之改裝費用，導致民眾願意去執行的意願降低。從實際情形來看，液化石油氣與汽油之價差約57%以上時，民眾改裝意願高，油氣價差約44%以下時，民眾願意改裝之誘因也下降，油氣價差約36%左右，改裝市場之改裝數量也較低。
建議政府應主導液化石油氣售價(需遠低於汽油價)，促使民眾主動改裝油氣雙燃料車，且車用LPG之價格應獨立與汽油、柴油浮動調價時一併連動調價。在人口居住密集之都會區，應提供路邊停車免費或優惠之條件，藉由多面向誘因，提升民眾使用低污染車輛之意願。

Through questionnaires, this study aims at investigating the execution strategies and subsidy measures under the promotion policy of gasoline-LPG dual-fuel vehicle by the government. According to the investigation, 36.2% of the repliers thought that the subsidy is too low to be economic incentive, and 21.3% answered that the application is too complicated. For different subsidy measures, 42.2% agreed on the subsidy of the new purchase or the change to low emission vehicle, 34.6% agreed on the reduction of fuel tax or parking fee, and 21.5% preferred on the subsidy of LPG cost.
According to the economic effectiveness analysis of this study, it is estimated that the use of gasoline-LPG dual-fuel vehicle can have an annual saving of 50,829.1 NT dollars as compared to that of the gasoline vehicle. If the saving is converted to gasoline fuel consumption, 1,585.4 liters of 95 lead-free gasolines can be saved each year.
It is found in this study that, the public’s willing to use dual-fuel vehicle is lowered because the public still has to pay most part of the cost for the change of vehicle. Moreover, when the price difference between LPG and gasoline is higher than 57%, the willing will increase; lower than 44%, the willing decreases. When the price difference is lower than 36%, the amount for the change of gasoline to duel-fuel system will slow obviously.
It is suggested that the price difference between LPG and gasoline should be kept remarkable to enhance the public to change the gasoline vehicle to duel-fuel system. The LPG price for vehicle should be modified with those of gasoline and diesel. In metro area with high population density, preferential measures for parking and other incentives will enhance people to choose duel-fuel vehicles.
