Patent Analysis On Electric Vehicles And Research On Developmental Countermeasures In China

The automotive industry is one of the leading industries in the process of industrialization of a country, and whose developing level is an important indicator of industrialization in a country. However, the energy consumption structure of traditional vehicle not only has made a pressure on the growing energy crisis and environmental problems. But also do not meet the concept of low-carbon economy.Faced with such contradictions, developing new energy vehicles, especially electric vehicles, becomes an important way to relieve and improve the current plight of the automotive industry. Therefore, developing actively electric vehicle industry, and formulating developmental countermeasures according to our country conditions, has important strategic and practical significance for China.As one of the most important manifestations on research and innovation, patent contains a wealth of technical information, market information and legal information. Through a comprehensive analysis on patent documents, we can reveal the important information such as R&D strength, R&D direction, R&D focus, and market developmental strategies about relevant industry or enterprise. Full use of this information to improve their innovation, developmental capability, and the overall competitiveness, we can have a multiplier effect. So having an analysis on patent information at home and abroad in electric vehicles can provides an important reference for formulating electric vehicles industry developmental countermeasures in China.This dissertation, firstly, discusses patent analysis theory and technology development of electric vehicles, which is the basic research for comparative analysis of electric vehicles patents at domestic and foreign. And patent analysis theory includes the significance, methods and applications of patent analysis, Etc; Technology development of electric vehicles include the developmental history, main types, key technologies, and current outstanding issues.Secondly, the patent analysis theory was introduced into the patent study of electric vehicles at home and abroad, and with which, we have respectively an analysis on some indicators, such as annual distribution, technology distribution, main Applicants and inventors in the form of visual, as to have an detailed comparative analysis on the differences and gaps between domestic and foreign in developmental trends, R&D strength, R&D focus, Etc.Then, Combine with the results of patent analysis and other information necessary, we have a comprehensive analysis of the advantages, weaknesses, opportunities and threats of our electric vehicle industry with SWOT analysis from the various aspects,such as technology, talent, resources, innovation and developmental environment, and based on which, we propose developmental strategy of electric vehicle industry in China. Finally, Integrate the concludes of patent analysis and SWOT analysis, especially, the selected developmental strategy of China's electric vehicle industry, draw lessons from the developmental experience of foreign electric vehicle industry,and based on the Domestic development initiatives, we formulate developmental countermeasures for electric vehicle industry from the national, industry and enterprise levels,which can provides an important reference and decision support for the electric vehicle industry in China...
