Research On Breakthrough Paths And Strategies Of Graphene Production Technology Based On The Perspective Of Patent Analysis

Graphene is one of the most important development areas of China’s strategic emerging industries.It has great values of potential applications and markets in the fields of energy storage,electronic information,composite materials,medical,aerospace and other fields.In2015,the Ministry of Industry and Information Technology,the Development and Reform Commission and the Ministry of Science and Technology jointly promulgated the “Several Opinions on Accelerating the Innovation and Development of Graphene Industry”,clearly proposing strategic tasks such as expanding the graphene industry,building a pilot industry and developing key technological innovations.The innovation and breakthrough of graphene preparation technology has become the forerunner of the new step of industrial revolution.As the gap between China and developed countries in the manufacturing sector continues to shrink or even partially catch up,Chinese companies not only face increasingly strict technological blockades in developed countries,but also face greater technological development paths as industry leaders.As an emerging industry,the development of graphene requires strong technical innovation support.China’s graphene industry is facing new challenges of opportunities,paths and value creation models for technological innovation.The theories and methods of the technological innovation management that need to keep pace with the technological innovation practice of enterprises.Through the patent information mining and analysis in the industrial field,establishing a knowledge-driven decision support system,realizing the path scientific guidance and practice of industrial technology innovation,can provide more efficient and reliable guidance for industrial development,and also a strategic decision for industrial development.During the period from 2016 to 2018,more than 74000 patents were produced for graphene in the world,which will help transform future patent achievements into industrial achievements.Through the patent analysis in the field of graphene production,the technological innovation trend of graphene production is obtained,and then the breakthrough path of graphene production technology has important theoretical significance and application value for the current technological innovation of graphene preparation in China.Based on this,this paper takes the world graphene patent as the research object,constructs the graphene patent text knowledge base through the deep mining of the patent text,establishes the innovation evaluation system based on the entity association relationship,and proposes the path of the breakthrough of graphene production technology in China.Correspondingly,the main research content of this paper is divided into the following three parts:The first part is the navigation analysis of global graphene preparation patents.Using the Inco Pat patent database,in view of the current state of patents in the global graphene production,from the “global-China” level,the development of the graphene industry,patent application trends,key patent arrangements,and main applications in the field of innovation,we conduct comprehensive and multi-level patent navigation analysis.The graphene production technology,distribution trend and key R&D trends in key high-tech application areas such as lighting materials and electronic devices are obtained.It provides scientific and reasonable support for patent evolution analysis and innovation evaluation,as well as breakthrough innovation strategies.The second part is the evolution analysis and innovation evaluation of graphene patents.The knowledge map construction technology is used to complete the extraction of patent information,realize the core related matters and key processes in the patent text,and establish a patent text mining knowledge base.Based on the knowledge base,through the similarity analysis algorithm on the entity relationship,a knowledge base citation relationship of patent process information is established,and a new technological innovation evaluation system is constructed.In this way,an innovation evaluation system is established through patent related relations and citation relations.The evaluation of the major innovations in the graphene production is given.Finally,a technical breakthrough path and strategy based on patent knowledge graph is proposed.The technological breakthrough path and corresponding strategy are the strategic decision-making basis for the rational layout of the industry and the support of technological innovation.Based on the patent knowledge graph and the innovation evaluation system,this part establishes the technical breakthrough path of graphene prroduction.Then the core technology path of graphene preparation is reviewed.Finally,the breakthrough path of core technology for extracting graphene by patent knowledge map is proposed.Finally,the corresponding technology development strategy is proposed.Graphene and its application technology are the long-term strategic development direction of high-tech materials industry.Its technological breakthrough path and strategy are an important part of current technology innovation management research.At present,there is no mature research to introduce patent text knowledge graph and patent knowledge innovation evaluation of technology innovation.In order to solve this problem,this paper introduces text mining and intelligence analysis methods into the breakthrough path research of graphene production technology,and further systematically studies the technological breakthrough path based on knowledge graph.Through the application of data mining methods,a scientific research method for graphene technology innovation management is systematically proposed.Therefore,in-depth study of this issue will help to enhance the ability of industrial innovation to drive development,rational allocation of industrial innovation resources,improve the overall quality and competitiveness of the industry,and strengthen the leading role of technological innovation in industrial planning and development decisions.It also has profound guiding significance for management practice and application.
