As a new economic form, the digital economy has become a crucial driver of economic growth. The relationship between the sixth-generation mobile communication (6G) and the digital economy is characterized by mutual promotion and dependence, with significant value in key technology research and intense international competition. This study systematically reviews the principles and current development status of key 6G technologies from three dimensions: 6G wireless technology, network technology, and security technology. It evaluates China’s global competitiveness in these key technology directions, specifically including wireless artificial intelligence (AI), massive MIMO technology, terahertz communication, intelligent reflecting surfaces, integrated sensing and communication, distributed networking, space−air−ground integrated networks, AI‑native networks, computing power networks, physical layer security, network layer security, and data security and privacy protection. The study strongly recommends expedit
