Abstract

This study analyzes user satisfaction and perception change toward electric rental cars if an electric rental car user has encountered queue in a charging station and navigated other available stations. An ordinary least squares model of electric rental car user satisfaction and an average treatment effect model of perception change toward electric vehicles are specified. Using behavioral data collected from a survey of 196 electric rental car users, the models are estimated. Results show that the experience of turning back in a charging station has negative effect on user satisfaction and perception change toward electric vehicles. These results provide policy implications as follows: more public chargers are needed in Jeju; the installation of chargers should cover hotels; and more information on chargers should be available, including the location of charging stations.

본 연구에서는 전기렌터카 이용자가 충전소 대기수요로 인해 다른 충전소를 찾은 경험이, 전기렌터카 이용 만족도와 전기차에 대한 인식 변화에 주는 영향을 분석하였다. 전기렌터카 이용실태 설문조사 자료를 이용하여 분석을 수행하였고, 이 자료의 유효표본수는 196명이다. 분석을 위해 전기렌터카 이용 만족도에 대한 최소제곱 모형과 전기차 인식 변화에 대한 평균처리효과 모형을 설계하였다. 분석결과, 최소제곱 모형에서는 충전소 회차 경험이 전기렌터카 이용 만족도에 부정적인 영향을 미치는 것으로 나타났다. 평균처리효과모형에서는 회차 경험자의 전기차에 대한 인식 변화가 회차 비 경험자에 비해 부정적인 것으로 나타났고, 회차 경험자 자신이 회차를 경험하지 않았을 때를 가정하여 비교하면, 인식 변화가 더욱 부정적인 것으로 나타났다. 이러한 연구결과는 제주도 내 더 많은 개방형 충전기의 확충, 숙박업소 내 충전기 설치기준 마련과 충전기 보급지원, 전기렌터카 예약 단계에서 충전소 정보제공 시스템화 등의 필요성에 대한 시사점을 제공한다.
