The Internet is known as the "fifth space" and is often regarded as the "biggest variable".

  Currently, China has the largest digital society in the world, with more than 1 billion netizens. Regarding the Internet, the "biggest variable," some of Xi Jinping's clever metaphors are profoundly enlightening.

  The biggest variable is, first of all, the arrival of the digital society.

  "The one who knows the leakage in the house is under the roof; the one who knows the leakage of government is in the grass." This is an old saying.

  At the Internet Information Work Forum held on April 19, 2016, Xi Jinping quoted this sentence and said that many netizens call themselves "grassroots", and the Internet is now a "grassroots".

  Netizens come from ordinary people. When ordinary people go online, their public opinion will also go online.

Xi Jinping used "grass fields" as a metaphor. On the one hand, he emphasized the role of the Internet in reflecting social conditions and public opinion, and on the other hand, he also pointed out the significance of building a good network ecology.

  "Positive energy is the general requirement, managing it is the last word, and using it well is the real skill" "Building concentric circles online and offline" "Cyberspace is not a 'lawless place'"... Since the 18th National Congress, Xi Jinping has Cyberspace ecological governance has been mentioned on many occasions. Correspondingly, with the follow-up of a series of policies, regulations and special governance in the past ten years, China's comprehensive network governance system has been continuously improved.

  During the Spring Festival this year, from the online shopping craze led by "Going to the Market on the Cloud" to the "out-of-circle" interaction between cultural and tourism departments and netizens, to the lively and warm "Online China Festival" in various places, the public can intuitively feel that a sunny day A clear cyberspace is what the people want and what the government wants.

  The biggest variable also comes from network security challenges.

  "Internet core technology is our greatest 'vital gate'", Xi Jinping once emphasized the importance of Internet core technology to network security and national security.

He explained with the image of "building a house", "It's like building a house on someone else's wall foundation. No matter how big and beautiful it is, it may not be able to withstand the wind and rain, or even be vulnerable."

  The development of information technology continues to expand people's cognitive boundaries for "security".

From cyber violence and online fraud to hacker attacks and artificial intelligence weapons, while the Internet allows humans to enjoy convenience, the "double-edged sword" effect of the technology itself has become increasingly prominent.

  As early as 2014, Xi Jinping put forward the important conclusion that "without network security, there is no national security", elevating network security to a strategic level of national security.

  Over the past ten years, China's network security capabilities and key core technologies in the information field have continued to improve, regardless of the promulgation of regulations such as the Cybersecurity Law and Data Security Law, or the leadership of technologies such as 5G and Beidou.

In addition, since 2014, the National Cyber ​​Security Publicity Week activities held nationwide for ten consecutive years have made "cyber security for the people, and cyber security depends on the people" a consensus among the people.

  The largest variable that can become the largest increment.

  In the Internet age, there are many challenges, but even greater opportunities.

  Xi Jinping once said clearly that in today's world, informatization is developing rapidly. If we do not advance, we will retreat, and if we advance slowly, we will retreat.

"We must strengthen the construction of information infrastructure, strengthen the in-depth integration of information resources, and open up the information 'main artery' for economic and social development."

  The metaphor of a "main artery" accurately reveals the key to seizing the new development momentum of the interactive network.

  In the past ten years, big data, artificial intelligence, industrial Internet, Internet of Things... China has built the world's largest network infrastructure, mobile payment, one-code universal access, live streaming, etc. The development potential and innovation vitality stimulated by the Internet , and also profoundly changed the production and lifestyle of Chinese people.

  Of course, the "arteries" must be connected and shared with the world.

In recent years, China has released the "International Cooperation Strategy for Cyberspace", proposed the "Global Data Security Initiative", and launched the "Global Artificial Intelligence Governance Initiative"... "Building a community with a shared future in cyberspace" has become China's plan for global Internet development and governance.

  The path to benefit always goes with the times.

For China, informatization has brought golden opportunities to the Chinese nation; for the world, the Internet has increasingly become a new driving force for development, a new territory for maintaining security, and a new platform for mutual learning among civilizations.

  Understanding this "biggest variable" and turning "variables" into "increments" are issues of the times faced by China and the world.
