基于专利数据挖掘的我国直缝焊管技术创新与发展研究
Research on Innovation and Development of China's Longitudinal Welded Pipe Technology based on Patent Data Mining
摘要
Abstract
Drawing upon the databases of the National Intellectual Property Administration and the China Patent Information Center,a technical path for searching,organizing,and analyzing patent data has been designed by adopting combination weighting-association network models,K-means clustering,and the Apriori algorithm.The construction of a patent dataset was undertaken with the objective of searching,organizing and quantitatively and visually analyzing relevant patent data for longitudinal welded pipe technology.The analysis reveals that the development of longitudinal welded pipe technology patents in China has undergone two distinct phases,with the year 2000 serving as a significant demarcation point,and is currently experiencing a period of substantial growth.At the macro-regional level,research and development capabilities were categorized into six clusters based on industry research and development trends,exhibiting characteristics of high regional concentration and uneven development,with extreme R&D performance in eastern coastal regions.At the meso provincial and municipal levels,Jiangsu province has been identified as a leading region in terms of both patent quantity and technological innovation.At the micro-competitive entity level,overall technological concentration is low,indicating no risk of patent monopoly.The technical opportunity analysis indicates that considerable development potential persists in the welding processes and alloy materials domains,particularly in auxiliary equipment used in welding processes and pipe fitting processing technology.Notwithstanding their relatively high innovation complexity,these regions possess the potential to evolve into future technological epicenters.关键词
