基于专利计量分析的全球糖尿病健康管理发展态势研究

Research on the development trend of global diabetes health management based on patent bibliometrics

目的:从专利计量的视角分析全球糖尿病健康管理发展态势。方法:2021年2月26日在德温特专利数据库检索全球糖尿病健康管理专利数据4 804条,进行数据清洗及同族专利合并后共计857条专利数据,利用excel和德温特数据分析工具DDA对专利申请趋势、技术来源国与市场布局、专利权人分布情况和类型、技术研发热点进行计量分析,利用气泡图、技术功能矩阵、词云图等对计量分析的数据进行可视化展示,以比较国内外糖尿病健康管理专利技术布局现状和发展特点。结果:全球糖尿病健康管理专利从1980年开始申请,中国糖尿病健康管理专利从2003年开始申请,至今呈缓慢增长态势;拥有糖尿病健康管理有效专利最多的国家依次是美国、中国、韩国、瑞士、日本,分别为153件、89件、50件、31件、14件,有效专利占比约为95%;全球糖尿病健康管理有效专利主要市场区域依次为美国、中国、韩国、欧洲专利局、日本及加拿大。中国约98%的专利布局在本国,专利申请中企业占比远低于美国(49% 比 95%)。中国与全球糖尿病健康管理专利的研发热点一致,均围绕“系统”展开,包括健康管理系统、糖尿病管理系统、血糖管理系统、葡萄糖监测系统和健康管理设备等。结论:美国和中国是糖尿病健康管理专利的前两大主要技术来源国和市场布局国,但中国专利申请国际化战略尚未展开,专利产业化程度有待提升。未来全球糖尿病健康管理专利研发将会继续表现出以信息系统、设备和工具为主导的发展态势。

Objective To analyze the development trend of global diabetes health management from the perspective of patent bibliometrics.Methods Data from 4804 global diabetes health management patents were retrieved from the Derwent Innovation patent database,and after data cleaning and merging of patent families,a total of 857 patents were used in Excel and big data analysis tool Derwent Data Analysis tool to analyze patent application trends and technology sources.Quantitative analysis of country and market layout,distribution and types of patent holders,technology research and development hotspots,visual display of quantitative analysis data using bubble charts,technical function matrices,and word cloud graphs and other methods were performed to compare the layout of domestic and foreign diabetes health management patent technologies,as well as status and development characteristics.Results The filling of global diabetes health management patent application began in 1980,and the Chinese diabetes health management patent application began in 2003,showing a slow-growth trend.The United States had the most effective patents for diabetes health management,followed by China,South Korea,Switzerland,and Japan,with 153,89,50,31,and 14 patents respectively.These five countries account for approximately 95%of effective patents.The main market areas for effective patents on global diabetes health management were the United States and China,followed by South Korea,the European Patent Office,Japan,and Canada.Approximately 98%of China′s patents were located in the country,and the proportion of companies in China′s patent applications was much lower than that of the United States,Japan,and Switzerland(49%vs 90%or more).The research and development hotspots of China′s and global diabetes health management patents were consistent with the various systems,including health management systems,diabetes management systems,blood sugar management systems,glucose monitoring systems,and health management equipment.Conclusions The United States and China were the top two major technology sources and market distribution countries for diabetes health management patents;however,China′s patent application internationalization strategy has not yet been launched,and the degree of patent industrialization requires improvement.In the future,global diabetes health management patent research and development will continue to show a development trend dominated by information systems,equipment,and tools.
