      abstract = {A new generation of information technology (IT), such as  artificial intelligence, cloud computing, internet of  things, has been transforming production and business  across the world profoundly. While Chinese internet  companies begin to play an increasingly important role in  the global digital economy by pushing forward the  technological frontier, existing studies focus on their  business models and ignore their rising technological  capabilities. Based on natural language processing (NLP)  based text mining and network analysis of patent data, this  paper examines whether and how IT companies realize  technological catch-up through innovation in emerging  economies by comparing three leading internet giants in  China, namely, Baidu, Alibaba and Tencent with their US  counterparts. In particular, it investigates these three  technological companies' innovation strategy by analyzing  their (1) patent portfolios, technological focus, patenting  patterns and trends, and (2) the technological difference  between them and their US peers.},
