Based on China's new energy vehicle subsidy policy and considering geography factors and individual user experiences, this study discusses the popularity of new energy vehicles in medium-sized cities in China, identifies the reasons and factors may affect the diffusion of NEV.

The research focuses on Dalian, China, a city with subsidized new energy vehicle (NEV) policies. This study examines Dalian's NEV promotion policies through official documents and city council meeting minutes, comparing them with those of Beijing and Shanghai. NEV users in Dalian are surveyed on their experiences and reasons for adoption, while gasoline vehicle users are interviewed for additional perspectives to analyze alongside NEV data.

According to the Comparison with Shanghai and Beijing, Dalian lacks traffic restrictions, which while not directly proving the low NEV popularity, shows that individual users face fewer external influences. Environmental awareness is low among both vehicle types of users. Most gasoline vehicle users prefer Japanese brands for trust in the technology, while NEV users prefer BYD brand due to their suspicion of other Chinese EV brands. Secondly, the geographic factors in Dalian, particularly the low winter temperatures reducing battery activity by almost half, lead some users to prefer PHEVs, addressing range issues. Then, policy incentives, such as tax exemptions for PHEVs used mainly as gasoline vehicles, also affect choices. Media and social influence play a role, with petrol car users exposed to negative EV news and NEV users swayed by recommendations or media promotion, though skepticism about Chinese EVs persists.Even though the low temperature in Dalian affects battery activity, and that there are many other cities in China with similar environmental problems, the popularity of new energy vehicles in those cities are also very high. The popularity of new energy vehicles in Dalian is mainly based on users' own perceptions
