친환경 자동차 구매요인에 관한 실증분석 연구

Abstract

One of transport policy targets is to promote purchase and usage of the energy-efficient and eco-friendly cars (green cars) in the market. In the aspect of the environment, a reduction of CO2 emissions is a main goal of governments’ transport policies under the post-Kyoto Protocol. The objective of this study is to suggest efficient policy tools for boosting the share of green cars under the unstable global oil prices and to evaluate the favored government policy options and subsidies to households. We confine the research scope with the auto cars which are used in households sector. In order to establish the car type choice model we have carried out a survey on the household car ownership and to examine the willingness-to-pay with the stated preference analysis. We also carried out a survey of car ownership and usage during the peak period of fuel prices, in June 2008 and found some policy implications such as preferences of mid and large cars. After estimation of the model, we have found that small size hybrid car is more elastic than mid and large size hybrid car in all policy options. The ultimate policy goal of boosting the share of green cars is a reduction of greenhouse gases. However, we should remind the several policy goals such as “economic engine of auto industry”, and “revolution of environmental tax system” at the same time. The outputs of the study can draw following policy implications. Firstly, subsidies for purchasing of the green cars and discount of vehicle taxes would be very effective to encourage the usage and purchase of the green cars. Secondly, in order to boost the share of the green cars policy mix could be implemented to accomplish the certain level of share of the green cars in the introduction stage of the green cars.
