：经过多年的飞速发展，我国国内专利数量已经位居世界前列。然而我国的国际专利在世界范围的发展与影响仍然缺乏基于实证数据的系统研究。文章基于美国专利商标局（USPTO）发布的专利数据，从近400万件专利及引用网络中分析我国相关专利的发展态势与国际交流情况，以期为我国深度参与国际技术活动提供政策启示。研究发现，中国专利与特定地区的技术交流频繁，在某些技术领域具有显著特色，整体保持着良好的发展态势。不过，在USPTO专利数量和影响方面仍然与其他发达国家和地区存在明显差距。

After decades of fast development, China has listed at the top position in the world in terms of the amount of domestic patents. However, systematic research based on empirical data still lacks in the world-wide progress and impact of international patents from China. Based on 4 million patents and their citation network from the USPTO database, this study intends to unveil the international development and communication of USPTO patents from China, thus providing policy implications for China's deep involvement in world-wide technology activities. We find that, on the one hand, Chinese patents maintain frequent communications with certain areas in the world, exhibit prominent characteristics in certain technology fields, and keep a good momentum. On the other hand, however, China still has to catch up with other developed areas regarding its total number and impact of USPTO patents.
