The pattern of internet consumption has been established and the industrial internet era has begun. Moreover, industrial internet is twice as big as internet consumption, and in the future it will be generating mega-enterprises of billions of market value. However, china's industrial internet is generally at an exploratory stage, with bottlenecks such as lack of large-scale applications, lack of an open cooperative mentality and insufficient professional deep-farming capacity. Lemon beans serve as an early vertical industrial internet platform in the country, with major teams coming from well-known electronics and electronics manufacturing groups, with abundant resources. In april 2015, industry sensitivity was used to explore industrial internet construction and applications. Three years of mapping have successfully addressed the lack of large-scale internet applications in industry; the creation of a super-industrial internet platform that creates value for enterprises from the creation of r & d, informatization to the purchase and sale of the whole process. It currently covers five major industries (home appliances, smart electronics, vending machines, air cleaners, new energy vehicles). Three main platforms (the procurement supply chain management saas large data platform, the seal joint creation platform and the cross-border electrician platform) enable enterprises to upgrade their management, products and markets. At present, boshi, kanga, mei, hae-shin, fujin ice, the cold chain and tens of thousands of smes are users of lemon beans. Lemon beans are convinced that in the future, the entire chain of enterprise procurement, r & d and marketing will be carried out on the internet; the manufacturing business model is also shifting from a short-board to a long-board effect. This determines the future of the internet in industry. It will also work to become an industrial internet leader. Unlike the traditional b2b model, where the supply side is the starting point, lemon beans move from addressing many problems in the procurement supply chain to business services. The use of internet technology to destabilize supply chain management in traditional manufacturing industries has helped smes in industry to rapidly improve supply chain competitiveness, making professional procurement simple and enabling smes to have the procurement competitiveness of large enterprises。
