中国的互联网平台（BAT：百度、阿里巴巴、腾讯）在技术竞争力方面与美国的参与者（GAFA：谷歌、亚马逊、Facebook、苹果）相比，正受到越来越多的关注。本文利用中国和美国专利信息的文本信息，分析了百度对谷歌的技术追赶过程。基于文档级的嵌入结果，我们进行聚类分析，并生成新的指标的技术累积性和影响力的基础上邻居专利的内容空间。结果显示，百度遵循的是美国而不是中国的技术趋势，这表明百度在技术发展过程中积极寻求赶上美国玩家。与此同时，百度专利的影响力指数随着时间的推移而增加，反映了其技术竞争力的升级。
Internet platforms in China (BAT: Baidu, Alibaba, Tencent) are receiving growing attention in terms of their technological competitiveness compared to US players (GAFA: Google, Amazon, Facebook, Apple). Using text information of patent information in China and the US, this study analyzes Baidu’s technological catching up process with Google. Based on document-level embedding results, we conduct cluster analysis and generate new indicators of technology cumulativeness and impact based on neighbor patents in the content space. The results reveal that Baidu follows a trend of US rather than Chinese technology which suggests Baidu is aggressively seeking to catch up with US players in the process of its technological development. At the same time, the impact index of Baidu patents increases over time, reflecting its upgrading of technological competitiveness.
