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.
New energy vehicle technology is a new type of vehicle based on the concept of sustainable development in China. In terms of functional use, it can reduce the content of toxic gas and carbon dioxide in vehicle exhaust and reduce the impact on urban air quality by means of electric energy or mixed energy. At the same time, with the characteristics of new energy, it can effectively alleviate the problem that non-renewable energy is almost exhausted, and make the construction of urban economic system more suitable for the development situation of sustainable development concept. In this paper, based on the analysis of the types of new energy vehicles, it is expected to provide a good reference for the subsequent research and development of new energy vehicles.
As a new industry, the healthy development of new energy vehicle industry is of great significance for effectively solving environmental problems and energy crises. The purpose of this study was to analyze the technological innovation process of China’s new energy vehicle enterprises and construct the evaluation index system of technology innovation efficiency of China’s new energy vehicle enterprises and SBM model-based network DEA model from the two aspects of technology research and development stage and achievement transformation stage. The overall technological innovation efficiency and staged efficiency of 16 listed new energy vehicle enterprises in China were measured and combined with the Malmquist Index Model. The technical change and efficiency change of 16 listed new energy vehicle enterprises in China, spanning from 2012 to 2018, were analyzed. The results show that the average overall efficiency of technological innovation of 16 new energy automobile companies is 0.5515, and the standard deviation is 0.2341. It reflects the low overall efficiency of technological innovation of Chinese new energy vehicle enterprises and the uneven development and the huge gap between different enterprises. From 2012 to 2018, the M index is less than 1, and the technical level change (TC) has a greater negative impact on the M index.
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.
