Table 5 shows statistical information of the estimation results. The causes for
individuals’ latent preferences are the social-demographics of the respondents. All of the
variables are classified into two categories (dummy variables). We find that men over 50
years old are more environmentally concerned and have more positive attitudes toward EVs.
One possible reason is that the men over 50 years have relatively higher income, which
enables them to buy EVs easily. Besides, they have a higher expectation of the future
prospects for EVs, compared to other respondents. Thus we would as well recommend that
this group of consumers be taken into consideration by auto makers and in policy
development to achieve a high acceptance of EVs.
