Research On The Development Of Chinese Search Engine Technology Based On Patent Analysis

Since the 21 st century,it has become the consensus of all countries whichknowledge has become an important driving force for economic development.Developing knowledge-intensive high-tech industry has also become a strategic measure in many countries.Under the background of rapid development of the Internet economy,the market share of the search engine is also growing rapidlyin the whole Internet industry.Presenting rich profit margins and diversified profit model,the search engine has been recognized as the "fourth pot of gold of Internet after advertising,online games,wireless value-added.As the basis and core technology of collection and processingInformation in Internet industry,the applicationareaof search engine technology is quite extensive.Published in October 29,2015,"Thirteen Five-Year Plan Recommendations"to expand the economic space of network,implement the "Internet+" action,develop internet of things,implementing national big data strategy,promote open sharing of data resources,which can't carry out without the participate of search engines.Under the background of recession and looking for economic transformation,information technology industry is becoming a research hot spots in each country.Currently,in order to gain a leading edge in the future market,countries and companies have alreadymadethe layout in the field of patents,It has formed a competition of three pillars the United States,Asia and Europe currently.Exploring the intellectual property question of the search engine industry is of great significance to the realization of the depth of integration of information technology and industrialization,Formation of information technology innovation,enhance the level in the international industrial chainrelying on our new generation of information technology,realize the change from large to strong of China's information industry.This research takes the search engine industry as the research object,Based on patent date from CNIPR and INCOPAT Innovations Index,combined with the information of patent application and patent law status,through the patent application trend,technical field,country distribution,patent applicant and other indicators,a comprehensive analysis of the competitive situation of China's search engine industry is carried out from competitive environment and competitive strength two dimensions.Furthermore,by further excavation of the patent text clustering,a comprehensive understanding of the state and discovery trends of the technical field will be found.At the same time,through a large number of data statisticsin a certain period of time,this paper establish economic modelbetween the patent output and the total output value of China's search engine industry,the patent output and economic output of enterprises,the purpose is to test the effect of the patent.The analysis results show that: there is a significant correlation between the patent output and the output value of the search engine industry,and a strong correlation between enterprise patent output and economic performance,the regression correction model and statistical data established in this paper are in line with the requirements of statistical indicators.Finally,combined with the above analysis,this paper explores the problems in the industry,and put forward relevant suggestionsin order to provide support to the government and industry,and summarized the limitations of this research,and the prospect of further research on the patent of the search engine is proposed.
