In order to protect the environment and reduce energy consumption, new energy vehicles have begun to be vigorously promoted in various countries. In recent years, the rise of intelligent technology has had a great impact on the supply chain of new energy vehicles, which, coupled with the complexity of the supply chain itself, puts it at great risk. Therefore, it is quite indispensable to evaluate the risk of the new energy vehicle supply chain. This paper assesses the risks faced by China’s new energy vehicle supply chain in this period of technological transformation. First of all, this paper establishes an evaluation criteria system of 16 sub-criterion related to three dimensions: the market risk, operational risk, and the environmental risk. Then, variable weight theory is proposed to modify the constant weight obtained by the fuzzy analytic hierarchy process (FAHP). Finally, a risk assessment of China’s new energy vehicle supply chain is carried out by combining the variable weight and the cloud model. This method can effectively explain the randomness of matters, and avoid the influence of value abnormality on the criteria system. The results show that China’s new energy vehicle supply chain is at a high level. Through the identification of risk factors, mainly referring to the low clustering risk, technical level risk and information transparency risk, this paper can provide a risk prevention reference for corresponding enterprises.

New energy vehicles(NEV) as a new thing for sustainable development, in China, on the one hand has faced the rapid expansion of the market; the other hand, for the new NEV users, the current NEVs cannot keep up with the degree of innovation. This paper demonstrates the reasons for the existence of this systematic challenge, and puts forward the method of UX research which is different from the traditional petrol vehicles research in the early stage of development, which studies from the user's essence level, to form the innovative product programs which meet the needs of users and being real attractive.

In recent years, in order to promote the independent development of the new energy vehicle industry, Chinese government has decided to reduce the consumption subsidies for new energy vehicles until the subsidies are completely withdrawn. The reduction of consumption subsidy has a great impact on the production and sales of new energy vehicles in the whole vehicle market. However, does the reduction of this subsidy also have an impact on other enterprises in the new energy vehicles industry chain? This paper tests this problem using data from 2016 to 2018, and finds, through empirical analysis, that during the period of subsidy decline, the profitability of component enterprises is significantly positively correlated with this subsidies, while the r&d investment of enterprises is significantly negatively correlated with this subsidies. The results show that in terms of profitability, the reduction of consumer subsidies not only has an impact on the whole vehicle industry of new energy vehicles, but also has an adverse impact on the core component companies in the industrial chain. However, in terms of r&d, the reduction of subsidies has more negatively strengthened the input and attention of R&D in component companies.

With pm2.5 and environmental pollution problem of urban smog, energy conservation and environmental protection has become an important subject in the current car development, so the new energy vehicles get more and more favor from the government and enterprises. But the new energy vehicles’ market share in our country is still small and the technology is not mature. This paper summarizes the experience and lessons in the development of new energy vehicles at home and abroad, and then based on which analyses the reasons that restrict the development of the new energy vehicles, finally puts forward the countermeasures of new energy vehicles development from the government's macro policy, battery technology, management mechanism, public participation and so on. In addition, it also puts forward a new opinion that encourages and guides the social capital to participate in the operation of the new energy vehicle infrastructure construction and operation, then provides a model for our country’s new energy vehicles future development.

From the perspective of crude oil price, this paper investigates the effects of new energy vehicles on air quality by applying a time-varying parameter–stochastic volatility–vector autoregression model. NEVs benefits from the continuous adjustment and improvement of subsidy standards by the Chinese government, and the share of new energy vehicles in the market has been continuously improved. The empirical results show that the increase in new energy vehicles can reduce PM2.5 emissions, which is also consistent with the energy and environment theoretical model, and replacing traditional energy with new energy is helpful for controlling environmental pollution. Oil price has a direct negative impact on PM2.5 concentration, and the influence of new energy vehicles on air quality is also regulated by changes in oil price. A high oil price leads to an increase in driving costs, and consumers are more inclined to purchase new energy vehicles, which achieves the purpose of improving air quality to a certain extent. To improve the air quality, the relevant departments should adjust the subsidy policy of new energy vehicles according to the change in oil price and appropriately increase gasoline or diesel consumption taxes to provide development space for the new energy vehicle market.

In this paper, multidimensional evaluation model is made to select and analysis the new energy vehicles developing direction, namely to maturity, cost, energy resources, pollution and greenhouse gas emissions, energy efficiency and technical characteristics. And the research results show that, China should take the new energy vehicle technology line with "oil-electric hybrid, pure electric, improved hybrid- hydrogen fuel cell (hydrogen power), rechargeable hybrid" as the main line, and adjustment should be made with the technology innovation, industrial development, conditions and so on.

The corporate average fuel consumption (CAFC) and new energy vehicle (NEV) credit policy (2021–2023) was officially released in June 2020. As a mandatory regulation for automobile manufacturers to produce new energy vehicles, its impact on the output of new energy vehicles needs to be systematically evaluated. In this study, we build an enterprise policy compliance model to simulate the dual-credit policy requirements for the production of new energy vehicles from 2021 to 2023 under different scenarios. The results show that the production of new energy vehicles from 2021 to 2023 is required to reach 1.78 to 3.97 million under different scenarios. Three factors, i.e., switching from New Europe Driving Cycle (NEDC) to World Light Vehicle Test Procedure (WLTP) fuel consumption improvement of conventional vehicles, and credit per new energy vehicle, have a more significant impact on the new energy vehicle production than others. Under the minimum guarantee scenario, a 10% change in the above three factors will lead to a 2.5%, 1.5%, and 0.5% reduction in the production requirement for new energy vehicles.
