What kind of application space can be opened up when data flows westward and computing power flows eastward? An enterprise park in Xiamen, Fujian, is patrolled by unmanned security vehicles that can perform AI recognition and risk warning. The real-time audio and video, laser radar, and millimeter wave radar data collected by the vehicle are transmitted to the Ningxia Zhongwei Cloud Data Center through the 5G network, completing AI recognition and risk warning in just 100 milliseconds. The interconnection of computing power creates new possibilities for industries and regional synergy. With the booming development of the digital economy, the value of data as a factor of production is increasingly prominent, and computing power has become a new key productivity after heat and electricity. From transportation and meteorological services to data training, film and television rendering, online games... whether it is urban governance or enterprise operation, computing power support is needed. China is a country with abundant computing power resources, but computing power resources are distributed in a scattered manner, with idle and scarce computing power coexisting. For example, in the G60 Science and Technology Innovation Corridor of the Yangtze River Delta, the computing power in Songjiang, Shanghai is tight, and there is a large-scale queuing phenomenon between enterprises and scientific research projects. The utilization rate of computing power in Hefei, Anhui is about 65%. Solving the problem of supply-demand mismatch relies on building a unified data market and computing power market. And this is precisely an important aspect of building a unified national market. The interconnection of computing power requires not only the vigorous dismantling of "fences", but also the cultivation of "soil". Data elements have characteristics such as liquidity, high reusability, intangibility, and non exclusivity, which have natural advantages in assisting the construction of a unified national market. The interconnection of computing power aims to break down regional and industry segmentation, and enable computing power from different architectures, entities, and regions to move from "local data centers" to "national networking". Government departments, telecom operators, Internet enterprises and other various entities should work closely together to build mechanisms, build platforms, set standards, create ecology and other multi-dimensional forces, so that computing power can be truly connected into a network. The interconnection of computing power is a topic for high-quality industry development and a proposition for regional coordinated development. In 2022, China will launch the "East Digital West Computing" project to orderly guide the demand for computing power from the east to the west. This is the top-level design for cross regional allocation of computing power resources and connecting the main arteries of the digital economy. As one of the national hub nodes of the integrated computing power network, Ningxia leverages its advantages such as suitable climate and abundant renewable energy to reasonably allocate computing power resources, coordinate computing and electricity, and promote the development of digital industry clusters. At present, Ningxia provides cloud computing services to more than 4000 enterprise users, and more than 20 large models have been trained in Ningxia. In recent years, riding on the east wind of "East Data West Calculation", data highways have been connected one by one, and data centers have "grown" in the western region. The advantages of data and computing power have been continuously transformed into economic growth momentum. Practice has shown that building a unified national market provides valuable opportunities for various regions to seize the digital economy and reshape their development advantages. Jumping out of a corner and looking at the overall situation, focusing on the needs of the country, thinking about one's own abilities, and adapting to local conditions to layout industries, can achieve greater development and greater achievements in the process of seizing positions and making up for them. The interconnection of computing power and universal access are the goals and advantages. In Guiyang, Guizhou, Zhong'an Technology Group Co., Ltd. has partnered with communication companies to build a "5G+AI digital twin factory", reducing operating costs and improving production and sales coordination efficiency. Qingyang, Gansu Province, has achieved precise monitoring and regulation of crop growth environment through the demonstration site of intelligent solar greenhouse IoT application. Thanks to the interconnection of computing power and the continuous reduction of computing power costs, more enterprises and rural areas can use and afford new technologies, allowing new stories of digital empowerment development to continue to emerge. Building a big market and connecting it into a network is just the first step. To fully leverage the amplification, superposition, and multiplication effects of digital technology, it is also necessary to focus on weaknesses and solve problems. For example, the core of computing power interconnection is data flow. In the process of cross regional and cross enterprise transmission and sharing, how to ensure data security and user privacy? From a long-term perspective, building a unified national market cannot be achieved overnight. Strengthening problem awareness and guidance, and solving any problems that arise, can make the market more prosperous. Unicom is the market, nurturing opportunities, and accumulating new momentum. Taking computing power as the fulcrum, leveraging the economic cycle, and promoting the deepening and solidification of the construction of a unified big market, the Chinese economic ship will surely ride the wind and waves, move steadily and achieve long-term success.
