The recently held 2023 Smart Expo Industrial Metaverse Forum provides a deep understanding of the key elements, supporting technologies, scenario applications, and industrial system structure of the industrial metaverse, and explores new models for the development of industrial metaverse applications. The industrial metaverse is a higher form of industrial internet development, and the development of the industrial metaverse needs to be based on the great development of the industrial internet. At present, the industrial internet is accelerating the comprehensive connection between the industrial chain, value chain, and supply chain, building a new industrial service system, and effectively helping enterprises improve production efficiency and reduce costs. In the new wave of technological revolution and accelerated industrial transformation, the industrial internet plays a crucial role. Our country has a complete manufacturing system, a large market, multiple scenarios, and strong policy support. The foundation for developing the industrial internet is solid. Currently, the industrial internet has become an important force in accelerating the digital transformation of our manufacturing industry and supporting high-quality economic development. However, it should also be noted that small and medium-sized enterprises still have weak awareness of digital transformation, have a "thousand enterprises and thousands of faces" in the implementation of industrial internet, have low standardization level, insufficient industrial collaborative support ability, key technologies are subject to human constraints, insufficient safety guarantees, and a structural shortage of talent, which seriously restrict the high-quality development of China's industrial internet. To promote the large-scale application of industrial internet, we must adhere to the combination of problem oriented and goal oriented, seize key links such as technology, mode, service, and supervision, and break through the difficulties and obstacles in the development of industrial internet. Further accelerate key technological innovation, improve the industrial development ecosystem, improve new infrastructure, enhance the effectiveness of integrated applications, strengthen security capabilities, and overall enhance the level of industrial internet. Cohesive Industrial Internet Technology Innovation and Hardware Replacement. We will establish a sound innovation system with enterprises as the main body and collaboration between industry, academia, and research. We will make good use of mechanisms such as "unveiling and leading" and "horse racing" to accelerate the development of core technologies such as cloud computing, big data, optical displays, and artificial intelligence. We will also promote the upgrading of key equipment technologies such as control chips, optical devices, sensors, and memory, and break through technological bottlenecks that restrict large-scale applications. Accelerate the promotion of equipment interconnection, data innovation and application, and equipment platform security. Accelerate the construction of new infrastructure such as digitization and computing power, support industrial enterprises in using advanced technology to transform their networks, promote centralized construction of data center areas, and improve the level of cross regional computing power scheduling. Deepen the scale integration and application of industrial internet. Promote innovation in the application models of industrial internet in technology research and development, production, operation and maintenance, and supply chain management. Encourage basic telecommunications enterprises, internet platform enterprises, industrial enterprises, etc. to play a good role in the "team competition" of enterprise digital transformation. Promote the "chain network collaboration" between the industrial internet and the industrial chain supply chain, and promote the popularization and application of the industrial internet in key industrial chains such as electronic information and engineering machinery. Encourage and support leading enterprises to drive upstream and downstream enterprises to integrate into the industrial internet, and promote the understanding and use of the internet by small and medium-sized enterprises. Continuously deepen the integration and innovative application of "5G+Industrial Internet", cultivate and create a batch of "5G+Industrial Internet" application benchmark demonstrations. Promote the industrial internet to be rooted in industries, industrial parks, and county-level economies. Create an inclusive, prudent, and moderately relaxed governance environment. Adhere to inclusive and prudent supervision, and comply with
