A Study On The Factors Affecting Private Car Type Choice

With the continuous improvement of living standards and quality of life,private small car ownership has been increasing year by day,and the problems of road traffic congestion,traffic carbon emission and non-renewable energy consumption caused by the use of private cars are becoming more and more serious.The research on the choice behavior of the consumers in the gasoline automobile market and the new energy automobile market can not only enrich the study of traffic demand analysis,but also can be used to forecast the private car ownership rate.can provide the basis for car sellers,the production of cars to provide guidance.At the same time,it can provide the basis for the Government to make the relevant laws and regulations and adjust the policy from the government level by studying the preference of the choice of private car models.In this paper,a questionnaire survey was conducted to collect the personal and family information of the respondents,the existing vehicles and the usage information,and to consider the purchase of new energy models when buying a second car.A total of 439 questionnaires were issued and a valid questionnaire accounted for 85.9%.In the first part,according to the domestic car sales market and the ownership rate of different models,the household car is divided into 8 types,and the MNL model is constructed by using the information RP Data.In the second part of the survey data to buy a second car to consider the intention to purchase new energy models of the SP data to build MNL model.The variable parameter calibration and the significant test of two models were carried out by R language software.To analyse the factors and significance of the owners of private cars when they buy the existing models,and the factors and significance of considering the purchase of a new energy vehicle when they purchase the second car.The results of RP Data show that the ratio of vehicle price to income,the square of vehicle price and income ratio,the space of vehicle,the fuel consumption of vehicle,the number of household population and income and other variables have significant influence on consumers ' purchase intention when they buy traditional gasoline models.The estimated results of SP data show that the cost,price,mileage,the subsidy to purchase new energy models,the distribution density of charge piles,and the degree of recognition of new energy models can significantly affect consumers ' intention to buy new energy models.Age,sex,and academic background of different groups on the purchase of pure electric vehicle type of purchase intention is also different.The results obtained by the two parts of this paper can provide the guidance for automobile manufacturers to attract more consumers and the design and evaluation of the production vehicles,and provide the basis for the relevant departments to make reasonable restriction policies.At the same time,this study can provide reasonable suggestions for the popularization of new energy models and provide the basis for the relevant functional departments to formulate reasonable scientific policies.
