Recently, the 4th issue of “China Internet Communications” magazine, managed by the State Internet Information Office and hosted by the China Cyberspace Research Institute, was published in 2024 to commemorate the 30th anniversary of China's full access to the international Internet. Yang Yuanqing, Chairman and CEO of Lenovo Group, was invited to post an article reviewing the development process of Lenovo and China's 30-year intertwined internet turbulence, and put forward three major perceptions of the development of China's digital economy, and a judgment on how to develop new types of productivity in the AI era. Yang Yuanqing pointed out that a 30-year history of the development of the Internet in China is a history of breakthroughs and innovations in information and communication technology in China. It is also a history of China's continuous deepening of reform and opening-up, gradual strengthening of comprehensive national strength, and continuous integration into globalization. Since its establishment 40 years ago, Lenovo has taken root in the computer industry, insisted on technological innovation, pioneered international expansion, and deeply cultivated the real economy. It has contributed to the popularization of the Internet in China, to the globalization of Chinese manufacturing, and to the integrated development of China's digital economy and real economy.
