The Ministry of industry and information technology released the big data industry development plan for the 14th five year plan on the 30th. According to this plan, it is expected that by 2025, the estimated scale of the big data industry will exceed 3 trillion yuan, and the average annual compound growth rate will be maintained at about 25%. With the rapid development of digital economy, the big data industry has also ushered in a "tuyere". What will be the focus of developing the big data industry? As a strategic emerging industry focusing on data generation, collection, storage, processing, analysis and service, big data industry is the key support to activate the potential of data elements. The plan is clear. By 2025, the estimated scale of big data industry will exceed 3 trillion yuan. In particular, it is proposed that the value evaluation system of data elements is preliminarily established; The industrial foundation has been continuously consolidated and breakthroughs have been made in key core technologies; Form a number of big data products and services with leading technology and wide application. Innovation is the driving force of industrial development. "In the next few years, big data technology innovation will not only be at the level of cutting-edge technology development, but also the innovation ability and independent control level of the whole industry chain will be further strengthened, the underlying support ability of basic software and hardware will be continuously improved, and the integration and innovation of big data and cutting-edge technologies will be further deepened," said Yu Xiaohui, President of China Institute of information and communications. Zhang Li, President of China Electronic Information Industry Development Research Institute, believes that the open source of big data software and hardware has become an irreversible trend. We should widely gather intellectual resources, industrial resources and service resources to ensure the continuous iteration of industrial innovation as much as possible. In particular, the Ministry of industry and information technology proposed to accelerate the cultivation of data element market, strengthen the research and development of key products, innovate service modes and formats, and promote the deep integration of big data with various industries. Yu Xiaohui said that at present, China's big data product and service system focusing on "data resources, basic hardware, general software, industrial application and security" has initially taken shape, and industrial application innovation is active. By comparing the big data of energy consumption such as power consumption, load rate and loss, and combining with the data of enterprise production, State Grid Hangzhou Fuyang district power supply company provides enterprises with energy consumption diagnosis report and personalized energy consumption service; Combining big data in production, energy consumption and supply chain, a large number of small and medium-sized enterprises use digital technology to promote green production... The practice of big data services has been carried out in many fields. According to Tianyan survey data, there are more than 264000 big data products and service related enterprises in China. "In the future, we should also focus on cultivating professional and scenario based big data solutions, establish a map of big data products, and accelerate the development of data services to specialization, engineering and platform." experts believe that we will also accelerate the construction of industry big data platform, create mature industry application scenarios, and promote the deep integration of big data with various industries and fields.
