Research On Purchase Intention Choice Model Of Electric Vehicle Considering Latent Variables

With the excessive dependence and use of fossil energy,the problem of energy shortage and environment pollution is becoming more and more serious.Therefore,human beings are facing a series of severe challenges,and it is extremely urgent to seek a sustainable development path.In order to achieve sustainable development and maintain the living environment of human beings,governments of various countries put sustainable development on the national agenda and began to explore new industrialization development directions in order to reduce the dependence on fossil energy.In this context,electric vehicles have developed rapidly because of their improtant characteristics of saving energy and protecting the environment.Governments of various countries began to gradually promote electric vehicles with the intention of expanding their share in the automobile industry.However,because some consumers still do not understand the related technologies and performance of electric vehicles,and lack of understanding of the development and current situation of electric vehicles industry,they are still in a wait-and-see state in choosing and purchasing electric vehicles.Therefore,there are still some problems such as low sales volume of electric vehicles and low consumer acceptance,and the actual occupancy rate of electric vehicles is still quite different from the expected results.Therefore,starting from the psychological perspective of consumers,it is of great practical significance to explore the internal mechanism and psychological process in the process of their choice of electric vehicles,dig deep into various factors that affect consumers’ choice of electric vehicles,therefore,it is of practical significance to put forward practical promotion measures.In this study,a decision-making behavior framework for electric vehicles is proposed,which covers three influencing factors:individual socio-economic attributes,vehicle attributes and psychological latent variables that are difficult to observe directly,and a hybrid choice model is constructed to explore consumers’ choice behavior of electric vehicles.First of all,this study summarizes the existing literature,sorts out and analyzes various influencing factors in the process of consumers’ electric vehicle decision-making,and sorts out the external factors and internal factors that influence consumers’ electric vehicle choice behavior.According to the actual sitaution of this study,we set up a questionnaire containing various influencing factors,including personal socio-economic attributes,vehicle characteristics and related internal psychological factors that affect consumers’ choice behavior.The investigation method of combining Revealed Preference survey and Stated Preference survey was adopted to conduct random sampling field investigation in various business districts with large traffic volume in Urumqi.Secondly,the structural equation model is used to model and analyze the acquired data,and the multiple indicators and multiple causes models are constructed to study the correlation between each psychological latent variable and between different socio-economic attributes and each psychological latent variable,to explore the psychological process and internal mechanism in the decision-making process of consumers’ electric vehicles,to analyze and depict the internal psychological characteristics in the process of consumers’ choice of electric vehicles,and to study the differences and preference differences of people with different socio-economic attributes on each psychological latent variable.Finally,according to the results of the latent variable model,the adaptive value of each psychological latent variable is calculated,which is introduced into the random coefficient logit model as a new explanatory variable,and a Hybrid Choice Model considering psychological latent variables is constructed to explore the interaction of individual socio-economic attributes,vehicle attributes and psychological latent variable.This study provides a research framework for electric vehicles,which covers three factors: individual socio-economic attributes,vehicle attributes and psychological latent variables.The results show that psychological latent variables such as preceived usefulness have a significant impact on consumers’ electric vehicle choice behavior,and consumers’ electric vehicle choice behavior is influence by both directly observable factors and psychological factors that are difficult to observe directly.The maximum error between the random coefficient logit model and actual choice probability is 7.79%,while the maximum error between the hybrid choice model and actual choice probability is 4.05%,which indicates that the hybrid choice model has better estimation effect than the random coefficient logit model,and can better describe the decision-making process of consumers’ electric vehicles.The research results can provide theoretical support for relevant departments to further promote electric vehicles.
