The nation's total data output reached 41.06 zettabytes last year, up 25 percent year-on-year, while the added value of core industries of the digital economy accounted for about 10 percent of GDP, according to the "Digital China Development Report 2024" released at the summit.

Liu Liehong, head of the National Data Administration, said more efforts are needed to increase the supply of high-quality data and speed up the integration of data elements with AI, technological innovation and industrial development, in a bid to drive the high-quality development of the data industry.

By the end of this year, new computing power in major computing hubs will account for more than 60 percent of the country's total, and the use of green electricity in the newly built big data centers is expected to exceed 80 percent, he noted. Liu also called for efforts to accelerate the cultivation of a national integrated data market and establish standards and systems for data circulation and trading.
