제품효율성 분석을 통한 친환경자동차 시장의 활성화 방안 연구

Abstract

The purpose of this study is to evaluate product efficiency with the domestic eco-friendly vehicles to which attention is paid as next-generation vehicles, utilizing Data Envelopment Analysis (DEA) and present measures for securing the development direction and competitiveness of the domestic eco-friendly vehicle industry through this. This study included eco-friendly vehicles, including electric vehicles, hybrid vehicles, plug-in hybrid vehicles, and Liquefied Petroleum Gas (LPG) vehicles for the analysis. As for research data, with the domestic cars sold in the South Korean vehicle market, this study added and utilized data on general passenger cars sold from 2015 through 2018 and LPG vehicles sold for ordinary people in 2019 through the production and selling statistics of the Korea Automobile Manufacturers Association (KAMA) for the analysis. The input variable used for DEA analysis was car price. As output variables, converted fuel efficiency, engine power, and car body volume were used, and dummy variables indicating gasoline, hybrid, and Sport Utility Vehicle (SUV) were used. The results of empirical analysis in this study are as follows: First, to verify the usefulness of the indicator for measuring efficiency for the evaluation of the product efficiency of eco-friendly vehicles, this study conducted a comparative analysis of the technical efficiency model and allocative efficiency model based on the DEA model. To do so, this study estimated the weighted value of the efficacy given to consumers through Two-Stage Least Squares (2SLS) analysis utilizing the IV Logit model and utilized that in the measurement of allocative efficiency. Second, to examine if there is any difference in product efficiency according to the background variable by the type of consumption in the domestic vehicle market, a non-parametric approach was made. Third, This study extracted data by each measurement indicator of the input variable and output variables for the comparisons of all models of vehicles in detail by class and type and then conducted a comparative analysis of the prices in detail with the gasoline models occupying the largest proportion of sales as internal combustion vehicle models in the domestic vehicle market, utilizing them. Through this, this study conducted a comparative analysis of the economic differences with gasoline models by each model of eco-friendly vehicles. This study has a significance that it verified if the product efficiency utilizing the allocative efficiency of the DEA model would be a more useful scale to explain the efficiency of the domestic vehicle market and analyzed the efficiency from the consumer point of view through that.
