Abstract: Starting from consumer preferences, via a series of field interviews and questionnaire surveys, accessing to the demand-side of the first-hand data and using factor analysis and the Logit regression, the paper draws a conclusion that consumers pay attention to social- environmental benefits, technology properties, internal conditions and external attributes which consistitute four main factors of supporting infrastructure layout. In addition, consumers' awareness of the car has also changed, who pay more attention to the attitude of energy saving and emission reduction, preferring to buy more energy saving and better environmental-friendly models. On the basis of demand-side research, based on the actual situation of Chinese electric vehicle industry and its charging infrastructure, we can overcome technical bottlenecks, promote decentralized charging piles, integrate oil and electricity refueling station, and take full account of consumer preferences to further improve the supporting infrastructure layout of Chinese electric vehicles and promote the industrialization of electric vehicles.
