Study On Thetechnology Maturity Of New Energy Automotive Industry

As an important means of transport, the automotive brings convenience to us, while there are many problems such as energy crisis, air pollution, and so on. Under this background, the development of new energy automotive industry has become an important measure to alleviate the crisis of energy and environment. China also attaches great importance to the development of new energy automotive industry, and make it as a strategic emerging industry to focus on support from the fiscal, financial market, etc. But the rapid development of new energy automobile industry is affected and restricted by the technological maturity, so taking a research of technology maturity of new energy automotive industry is conducive for China to make correct selection of technology strategy.This paper focuses on the evaluation of technology maturity of new energy automotive industry. Firstly the research background, research significance, and related research at home and abroad were analyzed, and the innovation point of this paper was put forward. And then we describes the theoretical basis of this research required, such as the theory of TRL classification assessment, technology forecasting theory of TRIZ, social network analysis, media exposure method, technology maturity theory and method, and the orbital evolution, track transition of technological trajectory, which laid the theoretical foundation for the research of the following chapters. Secondly, based on the summary and analysis of the present research on the technology maturity, we proposed an evaluation system of multi dimension of technology maturity based on the bibliometrics and analysis of patent statistics. And then we took empirical calculation and analysis to the technology maturity of hybrid vehicles, pure electric vehicles and fuel cell vehicles of the three main types of new energy automotive by using the proposed evaluation system of multi dimension of technology maturity. And taking the hybrid vehicle as an example, we verified the validity and the objective accuracy of results calculated, through a thorough analysis of the index trend. After that, according to the results of technology maturity of each technology track of new energy automotive industry, combined with present situation of development of China’s new energy automotive industry, we put forward the selection of technological strategy for the development of new energy automotive industry in China. The strategy of technology improvement should be taken by the hybrid vehicle, the strategy of technology catch-up to pure electric vehicles, and the technology leading strategy to fuel cell vehicles. Combined with China’s special national conditions, the specific countermeasures of China’s new energy automotive industry development were put forward from the government level. Finally, we made summarizes to the front research of this paper, and put forward the problems and future prospects.
