中国发明与专利（知识产权情报学学报）

[目的/意义]通过分析中美之间在对方国开展专利申请的变化趋势和布局特征，对两国之间专利布局与双边经济贸易之间的关联性进行实证分析，旨在为中国加快高水平海外专利布局提供启示和对策建议。[方法/过程]基于incoPat专利数据库和中国统计年鉴，采用专利计量分析方法和可视化图表分析工具分析了中美在对方国专利申请的变化趋势，展示了专利技术的布局特征，重点讨论了专利布局特征与双边进出口贸易额、对外投资额、经济合作营业额等指标之间的关联性，开展了中在美专利申请与双边经贸合作关联性的实证分析。[结果/结论]中在美申请专利数与专利申请年份、中向美出口贸易额、中从美进口贸易额、中国科技研究与实验发展经费支出和美在华申请专利数之间均存在统计学上显著和正向的高度相关性，反映出二者之间的关联十分密切，为中国与主要贸易伙伴国建设共同发展繁荣的专利共同体和互赢互利的经贸合作关系提供了决策性参考。

[Purpose/Significance] Through analyzing the changing trends and layout characteristics of patent applications between China and United States(US) in each other's countries, an empirical analysis was conducted on the correlation between patent layout and bilateral economic trade between the two countries, aiming to provide inspiration and countermeasures for China to accelerate its high-level overseas patent layout. [Method/Process] Based on the incoPat patent database and China Statistical Yearbook, using patent econometric analysis methods and visual chart analysis tools, this study analyzed the changing trends of patent applications between China and US, presented the layout characteristics of patent technology, and focused on discussing the correlation between patent layout characteristics and indicators, such as bilateral import & export trade volume, foreign investment volume, economic cooperation turnover, etc. An empirical analysis was also conducted on the correlation between patent applications in China and US, and bilateral economic & trade cooperation. [Result/Conclusion] Research results illustrate high correlations between the number of patents applied by China in US with the year of patent application, or the export trade volume from China to US, import trade volume from China to US, expenditure on scientific and technological research and experimental development in China, or the number of patents applied by China. These high correlations are statistically significant and positive, and well reflect very close relationships between two factors, which provide decision-making reference for China and its major trading partners to build a common and prosperous patent community and mutually beneficial economic & trade cooperation.
