| Patent is an important support for China's innovation-driven development and construction about intellectual property powerful nation.With the rapid growth of the number of patents in China,the issue of patent quality is attracting more and more attention.And the improvement of patent quality has become an urgent practical problem for China's development of innovation.Therefore,China implements the patent quality improvement project,and the emerging industry has become the key area and important grasp for the improvement of patent quality in China.However,it is urgent to carry out empirical research to understand how to improve the patent quality in emerging industries.More importantly,the distinction in economic and technological level between different regions inside China is quite obvious.So research on the quality of Chinese patent requires further consideration of the heterogeneity between regions.In this context,this thesis selects integrated circuit manufacturing,graphene and high-speed railway as typical emerging industries.Then the patent quality status and its influencing factors of typical emerging industries in China are respectively studied from the national and regional level through the comprehensive application of patent bibliometrics,multi-index evaluation,econometrics and other methods.Based on large sample data,this thesis want to explore what is the patent quality,how to evaluate patent quality,what is the patent quality disparity between China and other major economies,what is the difference about patent quality between each region in China,what are the main influencing factors of patent quality,and what are the influencing paths and actual effects of influencing factors by above research.On this basis,this thesis put forward some effective suggestions on improving the patent quality of emerging industry in China.(1)Research on the concept definition about patent quality and the construction of evaluation index system.On the basis of existing research and discriminant analysis of related concepts,this thesis defines the concept of patent quality from three dimensions which includes technical quality,legal quality and economic quality.Then the "three dimensions-whole process" patent quality evaluation system which respectively suitable for single patent and group of patents are constructed based on the three quality dimensions and four forming stages: patent creation,patent application,patent examination and patent authorization.(2)Research on the domestic regional measurement of patent quality in typical emerging industries.Firstly,this thesis constructs technology classification systems and patent retrieval strategies respectively for three typical emerging industries.Then the Chinese patent database for emerging industries is built by searching and downloading patent data.Secondly,patent qualities of various regions in typical emerging industries are evaluated by text mining technology.Then the evaluation results are tested based on the results of the China Patent Awards.Finally,the difference characteristics between each domestic region for patent quality in typical emerging industries are revealed from the angel of time distribution,patentee type,technical subfields,quality dimension,single patent quality,etc.The research shows that the patent quality difference in various regions of China is obvious.(3)Research on the international measurement of Chinese patent quality in typical emerging industries.Firstly,this thesis downloads patent data and builds an international patent database for emerging industries by the patent retrieval strategy in English.Secondly,patent qualities of the world's major economies in typical emerging industries are evaluated by text mining technology.Then the evaluation results are tested according to the actual development status of various economies.Finally,the in-depth comparative analyses between China and other major economies for patent quality in typical emerging industries are respectively conducted from the angel of development trend,patentee type,technical subfields,patent office,quality dimension,etc.The research concludes that there is a gap between China and other major economies for patent quality in general.(4)Research on the influencing factors and influencing paths of patent quality in China.Firstly,based on content analysis method,this thesis identifies 58 influencing factors in five categories by field interviews and literature research.Among them,the patent subsidy policy,the standard and quality of patent examination is more important.Secondly,an influencing factor analysis model for patent quality is proposed on the basis of existing research.Finally,the influencing paths of important influencing factors are explored according the above model.The research also concludes that influencing factors which belong to innovation subject category is important,and that patent promotion policies should focus on enhancing the research investment and improving the patent management level of innovation subject.(5)Empirical research on the influencing factors of patent quality in Chinese typical emerging industries.Firstly,this thesis builds a function by selecting important factors in every category.Secondly,the econometric analysis is carried out by using the variable coefficient and constant coefficient panel data regression model.Finally,the regression results are tested from two aspects which include enterprise patents analysis and indirect effects analysis.This research concludes that the increase in research and development investment of patent owners,the delay of subsidize time of regional patent subsidy policy,the revision of the third patent law of China,the improvement of patent examination standards,the improvement of patent agent quality,the improvement of the economic level of the region and other factors has obviously promoted the improvement of patent quality and its three dimensions in Chinese typical emerging industries.Based on the above research,this thesis puts forward some suggestions for improving the patent quality in emerging industries from three dimensions which include technical quality,legal quality and economic quality.In addition,the suggestions are offered on the basis of each region's patent development strategy.The research results in this thesis have certain theoretical and practical significance for focusing on key issue we face on the implementation of the national intellectual property strategy,and for promoting the construction of intellectual property powerful nation and implementation of patent quality improvement project. |
