According to China Economic Net News, on December 18, the 2019 APEC SME Business Forum was held in Shenzhen. Zhang Nan, Chairman and CEO of Canaan Technology, attended the forum and delivered a keynote speech on "Connecting Everything with Computing and Integrating the World with Intelligence". Zhang Nanzhang said that the 2020 generation will be the 10 years of intelligent upgrading of the entire industrial economy, and the key to intelligent upgrading is whether it can improve the efficiency of social operation and improve people's lifestyle. And 5G, AIoT and blockchain will become the new infrastructure. As computing power and algorithms sink to the edge and end, enterprises will realize the transition from digitalization of business processes to intelligent production and service capabilities. Digital means is only an auxiliary for enterprises, and smart devices and smart services are new productivity. At the same time, the intelligentization of terminal equipment will bring smoother human-machine interaction and become a new user contact and value window.
