In recent years, the construction of digital industrial clusters in China has become more and more popular, and some places have carried out many positive explorations. What are the characteristics of digital industrial clusters with international competitiveness? Compared with the previously identified advanced manufacturing clusters and strategic emerging industrial clusters, what are the differences? What experience has each region formed in promoting the development of digital industrial clusters? Starting today, this edition will launch a series of reports on "Focusing on Digital Industry Clusters" to get close to the front line, understand the progress and look forward to the future.

A number of scientific research achievements and home-made alternative products, such as the world's first 128 layer 3D flash memory chip and China's first 400G silicon optical module, have achieved breakthroughs here. Speech recognition and artificial intelligence, visual recognition and core algorithms, optical fiber manufacturing and silicon optical chip research and development... Since the 18th National Congress of the Communist Party of China, with the continuous and rapid development of China's digital economy, a number of internationally competitive digital industry highlands, digital industry clusters and digital industry clusters have grown from scratch, from small to large, from weak to strong, providing strong support for promoting high-quality economic development in China. According to the statistics of China Electronic Information Industry Development Research Institute, more than 60% of the 25 advanced manufacturing clusters in China are dominated by digital economy. The vigorous development of the digital economy has driven the industrial cluster to speed up and shift gears. "Hello, I just arrived in Hangzhou...
