China?s current vehicle emissions caused by air pollution problems have become increasingly prominent. How to improve new energy vehicle market share, and effectively guide the consumer buying behavior become a problem, which the government and social have to be solved. In this paper, according to establish the stochastic evolutionary game model between the government and consumers in the car market, introducing of random factors analysis on the impact of evolutionary stability ,will obtain the stable strategy of government and automotive consumers. And on the basis of it, we study the government support, cost of vehicles, the use of cost, the utility of automobile use for the ways of evolutionary stability, with case further illustrates the external disturbance factors on consumer purchase of new energy vehicles in evolutionary game process stability. Studies show that: the increasing government subsidy policy, the reducing life cycle costs of new energy vehicles and the improving effectiveness of new energy vehicles will lead the model?s evolution to the orientation of consumer purchasing new energy vehicles.

Abstract Background: Battery charging mode is a prevalent method of transshipping power to new energy vehicles. Unfortunately, due to the limited capacity of batteries, typical new energy vehicles can only travel for approximate 350 miles on a single charge and require hours to be recharged. Battery swapping mode, as a novel alternative, can offer ideal solutions by depleted batteries being exchanged for recharged ones at swapping stations in the middle of long trips, thus will inevitably influence potential consumers’ purchase behaviors accordingly.Methods: To examine the impact of swapping mode and charging mode on consumers’ purchase intention, this paper examines a duopolistic market consisting of two new energy vehicle makers (i.e., new energy vehicle maker with swapping mode and one with charging mode), who adopting swapping mode and charging mode to service consumers, respectively. Considering swapping mode characterized with low initial investment and ease of use for consumers, the new energy vehicle makers with charging mode, capitalize on battery extended warranty service in response to rivals’ utilization of swapping mode, thereby non-cooperative game models are formulated, in which government subsidies are taken into account, both the optimal production decision for the new energy vehicle maker with swapping mode maker and one with charging mode are analyzed under three scenarios: without extended warranty service, with extended warranty service, and with extended warranty service and subsidy.Results: The results show that two makers’ market dominance relies on the ratio of the swapping station’s convenience to the extended warranty service and the valuation incremental rate. Additionally, we also find that the government subsidy can dramatically improve the performance of the new energy vehicle maker with swapping mode at the initial stage, but if the subsidy is insufficient size at the sequent stage, this will lead to policy failure and inefficiency in propelling the diffusion of swapping mode.Conclusions: The emerging swapping mode technology is a promising innovative one in boosting new energy vehicle diffusion, which will supplement to charging mode, thus reduce climate change dramatically

Exhaust pollution and energy crises are worsening worldwide. China has become the largest motor vehicle producer; thus, promoting the use of new energy vehicles (NEVs) in China has important practical significance. In this paper, considering the limited rationality of governments, NEV enterprises and consumers, we study the subsidy policy of the China NEV market using the evolutionary game and system dynamics (SD) methods. First, a tripartite evolutionary game model is developed and the replicator dynamics equations and Jacobian matrix are obtained. A SD simulation of the model was conducted to further clarify the impact of the initial market proportion and three variables used in the model. The results show that the initial market proportion affects the evolution speed but does not affect the evolution result when the three group players all choose a mixed strategy. For governments, they should not hastily cancel price subsidies provided to consumers; rather, they should dynamically adjust the rate of the subsidy decrease and increase the consumers’ extra cost for purchasing fuel vehicles (FVs). NEV enterprises should appropriately increase their investments in the research and development (R&D) of NEVs.

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.

In recent years, with the double pressure of energy crisis and environmental pollution, the development of new energy vehicles has become China's emerging strategic industry. In order to promote the development of new energy sedans, it is important to study the government subsidy of new energy sedan industry based on the consumer demand. This article firstly elaborates the government support experience of new energy sedan industry in foreign countries. Secondly, we demonstrate the necessity of government policy subsidy. Thirdly, we analyze the economy of new energy sedans based on the consumer demand. Then we make further analysis on the economy of new energy sedans according to the fuel price and the change of technical cost. Finally, we analyze the data, and put forward the government subsidy to promote the development of new energy sedans based on the consumer demand.

Based on the crash test of new energy vehicles, the mechanical response data of power batteries during the collision process were collected, and the average impact strength curve of power batteries of typical new energy vehicles in China was obtained. The average impact strength curve was mathematically processed to obtain the impact strength characteristic value and tolerance by using the equivalent trapezoidal wave and the least square method, thereby determining the test conditions of the dynamic strength of the domestic new energy vehicle power battery. The differences are analyzed by comparing with ISO 12405-3 test conditions, which provides an important reference for the revision of power battery test standards in the future.

The development of new energy vehicles is inseparable from the drive of consumers. Therefore, to explore the influencing factors of purchase behavior from the consumer's personal level is helpful for businesses to adopt corresponding sales strategies and the government to adopt relevant policies. Based on the individual level of consumers, this paper constructs a new energy vehicle purchase behavior prediction model from the review text, and explores the predictive effect of consumer personal factors on the purchase behavior of new energy vehicles. First of all, this paper proposes a quantitative method of consumer individual level factors, which combines word-of-mouth reviews with statistics. In this method, word2vec is used to train word vectors in word-of-mouth corpus to mine initial keywords, and core keywords are selected through statistical correlation analysis. Secondly, based on the core keywords of consumers' personal level, the gbdt model is constructed to predict the purchase behavior of new energy vehicles. The results show that the probability of correctly predicting consumers' purchase behavior is more than 72%.

Purchase subsidy has been adopted to accelerate the diffusion of New Energy Vehicles (NEVs) in China. With a Multi-stage Difference-in-Differences (DID) method, this research investigates the impact of purchase subsidy on Research and Development (R&D) efforts of NEV enterprises. The results indicate that purchase subsidy for NEVs has a positive and significant impact on R&D efforts of NEV enterprises. The impact increases when the purchase subsidy rate decreases. When considering the influences of government procurement and exemption on purchase tax, the positive impact of purchase subsidy still remains significant. The policy implications are that the purchase subsidy rate should be reduced, and stricter technological requirements should be set to couple with the purchase subsidy.

Recycling and gradient utilization (GU) of new energy vehicle (NEV) power batteries plays a significant role in promoting the sustainable development of the economy, society and environment in the context of China’s NEV power battery retirement tide. In this paper, the battery recycling subjects and GU subjects were regarded as members in an alliance, and an evolutionary game model of competition and cooperation between the two types of subjects was established. Evolution conditions and paths of the stable cooperation modes between these two were explored. Suggestions were proposed to avoid entering a state of deadlock and promote the alliance to achieve the “win-win” cooperation mode of effective resource recovery and environmental sustainability. The results revealed four types of certain situations, two types of uncertain situations, and one type of deadlock situation for the evolution of alliance cooperation. The factors of the market environment are evident in not only changing the evolution paths and steady-states of the alliance but also in breaking the evolution deadlock. However, the sensitivity of the members in the alliance to different types of parameters varies greatly. It is difficult for the government to guide the formation of an ideal steady-state of cooperation or break the deadlock of evolution by a single strategy, such as subsidies or supervision. The combination of subsidy-and-supervision or phased regulation should be adopted. Only increasing subsidies is likely to weaken the function of the market and have a counterproductive effect.
