Battery recycling policies for boosting electric vehicle adoption: evidence from a choice experimental survey

Electric vehicles must be widely accepted because of environmental concerns and carbon restrictions. Previous research has looked at consumer policy preferences and their influence on electric vehicle adoption. However, none have investigated the impact of policies linked to battery recycling on electric vehicle adoption. This study used a discrete choice model (the panel-data mixed logit model) to evaluate 552 actual consumer choice data from Southwest China collected via an online questionnaire. Our results indicate that (1) 75% of respondents feel that electric vehicles enhance the environment and are eager to embrace them. However, the lack of strong recycling policies may hinder their adoption of electric vehicles. Specifically, the four battery recycling policies significantly impact electric vehicle adoption. (2) Consumers appreciate producer-oriented incentives more than consumer-oriented incentives to a lesser extent, such as mandated battery recycling policies and electric vehicle battery flow tracing policies. (3) Consumers place a larger willingness to pay on charging station density than vehicle attributes. (4) Regarding consumer heterogeneity, the usual young group in higher-rated cities prefers electric vehicles, while customers who own a car are more inclined to buy electric vehicles. Finally, more management insights and policy recommendations are provided based on these findings to help government and producer policymakers.

Techno-economic analysis of the adoption of electric vehicles

Significant advances in battery technology are creating a viable marketspace for battery powered passenger vehicles. Climate change and concerns over reliable supplies of hydrocarbons are aiding in the focus on electric vehicles. Consumers can be influenced by marketing and emotion resulting in behaviors that may not be in line with their stated objectives. Although sales of electric vehicles are accelerating, it may not be clear that purchasing an electric vehicle is advantageous from an economic or environmental perspective. A techno- economic analysis of electric vehicles comparing them against hybrids, gasoline and diesel vehicles is presented. The results show that the complexity of electrical power supply, infrastructure requirements and full life cycle concerns show that electric vehicles have a place in the future but that ongoing improvements will be required for them to be clearly the best choice for a given situation.

Noise abatement and traffic safety: The trade-off of quieter engines and pavements on vehicle detection

Road traffic sounds are a major source of noise pollution in urban areas. But recent developments such as low noise pavements and hybrid/electric engine vehicles cast an optimistic outlook over such an environmental problem. However, it can be argued that engine, tire, and road noise could be relevant sources of information to avoid road traffic conflicts and accidents. In this paper, we analyze the potential trade-offs of traffic-noise abatement approaches in an experimental study, focusing for the first time on the impact and interaction of relevant factors such as pavement type, vehicle type, listener's age, and background noise, on vehicle detection levels. Results reveal that vehicle and pavement type significantly affect vehicle detection. Age is a significant factor, as both younger and older people exhibit lower detection levels of incoming vehicles. Low noise pavements combined with all-electric and hybrid vehicles might pose a severe threat to the safety of vulnerable road users. All factors interact simultaneously, and vehicle detection is best predicted by the loudness signal-to-noise ratio.     

Adoption of unmanned aerial vehicles for pesticide application: Role of social network,resource endowment,and perceptions

Unmanned aerial vehicle technology is a promising alternative for sustainable agriculture production to more traditional technologies used in China. This paper considers factors affecting adoption of unmanned aerial vehicles for spraying pesticides among farmers in Jilin Province, China. Gender (male), percentage of income from agriculture, cultivated land area, within-family village leadership, number of borrowing channels, and positive attitudes towards the technology had a positive effect on adoption intention. Positive attitude toward traditional technology and higher income had a negative effect. Policy recommendations include continued work in improving access to rural financing, facilitating early adopters, and technology promotion.

Examination of trust and sustainability concerns in autonomous vehicle adoption

The latest developments regarding autonomous vehicles (AVs) have drawn the attention of tech-savvy individuals and marketers. AVs are expected to cause a major change in the markets of vehicle selling, transportation and logistics. Therefore, it is crucial to understand consumer acceptance so that the companies in these markets can develop their penetration strategies accordingly and technology companies can shape their technology development strategies. This study aims to examine individuals' adoption attitudes toward AVs by considering trust and sustainability concerns. This was achieved by expanding the technology acceptance model (TAM). A survey of 391 participants was conducted and the data were analyzed using structural equation modeling (SEM). The results confirmed previous technology acceptance models by showing the relationships between perceived usefulness, perceived ease of use, and behavioral intention. Moreover, the direct and indirect effects of trust on behavioral intention were also shown. This study provides evidence to extend the TAM to the adoption of AVs by uncovering individuals’ sustainability concerns.     

Technology-push and demand-pull factors in emerging sectors: evidence from the electric vehicle market

Despite consensus on the mutual dependence of the technology-push and demand-pull factors, their interactions can depend on industry life cycles and domestic market status. Using patent and Google search traffic data, this study brings robust evidence supporting the hypothesis that technology development occurs ahead of market demand in the U.S. electric vehicle sector, while this is not the case in Germany. Market demand does not precede technology development in either country. This shows the importance of the technology-push factor and the role of the lead market in the electric vehicle sector. This study elaborates technology-push and demand-pull hypotheses with a focus on industry life cycles and domestic market status and contributes to the discussion on technology-push, demand-pull and mixed policies in emerging sectors.     

Formation of free-charging industry alliance for new energy vehicles
