碩士 === 國立臺北科技大學 === 環境工程與管理研究所 === 97 === This study aims at investigating the economic effectiveness and quantity reduction effectiveness in the promotion of the support policy of gasoline-LPG dual-fuel vehicle by the government. It can be seen in this study that in the support of the new purchase or the change to the low emission vehicle, the public’s willing is lowered because the public still has to pay part of the fee for the change of vehicle. Moreover, it is suggested that the LPG price should be adjusted along with the change of the gasoline price, that is, certain degree of price difference should be maintained; however, based on the current status, the price difference between LPG and gasoline has been greatly reduced, and the encouragement factor for the public to choose gasoline-LPG dual fuel vehicle is not too much. Take a look from the economic effectiveness analysis of this study, it can be seen that the use of gasoline-LPG dual-fuel vehicle can have an annual saving of 43,992 NT dollars as compared to that of the gasoline vehicle, in other words, if it is converted to gasoline fuel, about 1,516 liters of 95 lead-free gasoline can be saved each year. Face with the rising international oil price, the promotion of lpg dual-fuel vehicle can urge the change of taxi in the whole nation to lpg dual-fuel vehicle, which not only saves the fuel fee, but also can disperse the energy use and can reduce the pollution to the environment. Therefore, in this study, it is suggested that the original manufacturer should introduce the liquefied petroleum gas fuel vehicle designed itself and should provide later maintenance and warranty service so as to enhance the utilization rate of the liquefied petroleum gas fuel vehicle. It is also suggested that the local government should prepare the support method for the setup of gas station for the liquefied petroleum gas so as to encourage the current gas station and gas distribution site to operate the gas adding business to the public; in other words, through the enhancement of the convenience, the willingness of the driver for changing the vehicle would then be promoted. In addition, in highly populated metropolitan area, it is hoped that road side free parking or parking for half price can be provided for oil-gas dual-fuel vehicle, biodiesel oil vehicle, oil-electricity mixed vehicle or electric vehicle, etc. so as to enhance the willingness of the public to use the low pollution environmental protection vehicle.
