B2B is the exchange of products, services and information between enterprises through the Internet. Nowadays, the development speed of Internet-based B2B is very rapid, and it is urgent for small and medium-sized enterprises to carry out B2B. What are the authoritative B2B websites? Please 2014 top ten B2B website complete. I won't go into the details here. Category of inter-enterprise e-commerce: From the perspective of the types of inter-enterprise commerce targeted by the inter-enterprise e-commerce system, the current inter-enterprise e-commerce system can be divided into international e-commerce system for international trade business, e-commerce system for general business process and electronic banking system for payment and clearing process. The business activities between enterprises are relatively standardized, which can be divided into three stages: pre-transaction, transaction and post-transaction. According to these three different stages, the corresponding e-commerce system for the general business process also has three stages, which have great differences in technology. First, support pre-transaction (Pro-Trade/Transaction) e-commerce system. It mainly supports business information exchange and trade negotiation. This is one of the least technical requirements of the entire inter-enterprise e-commerce business. At present, most of the electronic commerce application systems in China are of this kind. (2) E-commerce systems that support Trade/Transaction. It mainly supports the exchange of various business documents or documents in the process of business activities between enterprises. Such systems generally have high requirements for the reliability of data exchange. Technically, there must be two points to ensure: first, the accuracy of data exchange; The second is the legal effect of document message record, which is usually guaranteed by the formulation of corresponding laws and the security of the application system. Support for Post-Trade/Transaction e-commerce systems. This kind of system mainly involves banks, financial institutions and payment issues, so the reliability and security of data exchange have high requirements. That is, it requires not only absolute reliability, but also strict confidentiality of account numbers, digital signatures (CA), bank accounts, and so on. The use of e-commerce system to complete the entire transaction between enterprises, not only requires the two sides of the transaction to be open to each other, but also must be connected to banks, certification bodies and other units, data transmission is mainly based on the Web. To complete the entire process of e-commerce transactions, it is not only necessary for enterprises to apply e-commerce systems, but also for enterprises and service organizations related to business activities to provide e-commerce service applications, such as banks to provide online banking services, e-commerce to provide certification services, etc. It is a systematic social project. Advantages of B2B: The implementation of e-commerce between enterprises will drive down the cost of enterprises and expand the source of enterprise income. The following will be analyzed in four aspects: procurement cost, inventory cost, turnaround time and expanding market opportunities. 1. Reduce procurement costs By establishing inter-enterprise e-commerce with suppliers, enterprises can realize online automatic procurement, which can reduce the manpower, material and financial resources invested by both parties for transactions. In addition, the purchaser can obtain discounts through the integration of the internal procurement system and unified procurement from suppliers. For example, Wal-Mart connects more than 3,000 supermarkets in the United States through the network to carry out unified procurement and distribution, and saves a lot of procurement costs through bulk procurement. 2. Reduce inventory costs Through the establishment of inter-enterprise e-commerce system with upstream suppliers and downstream customers, to achieve sales to determine production, production to determine supply, to achieve efficient operation and unity, to maximize the control of inventory. For example, by allowing customers to order online, Dell realizes the efficient operation of enterprise business processes and greatly reduces inventory costs. 3. Enterprises can also establish a unified e-commerce system with suppliers and customers to achieve direct communication and transactions between suppliers and customers, and reduce turnover links. For example, Boeing's spare parts are purchased from suppliers, and a large part of these spare parts are used to meet its customers' aviation maintenance aircraft. In order to reduce the intermediate turnover link, Boeing through the establishment of e-commerce website to achieve direct communication between Boeing suppliers and customers, greatly reducing the turnover time of spare parts. 4. Expanding market opportunities By establishing online business relationships with potential customers, enterprises can cover the market that is difficult to cover through traditional channels and increase the market opportunities of enterprises. For example, Dell, through online direct selling, 20% of its new customers come from small and medium-sized enterprises. Through the establishment of inter-enterprise e-commerce with these enterprises, the transaction costs of both sides are greatly reduced, and the benefits of online purchasing for small and medium-sized enterprise customers are increased. B2B development trend: As far as the B2B market development momentum is good, but there is still an immature side of the B2B market. This immaturity is reflected in the many innate trading advantages of B2B transactions, such as online price negotiation and online collaboration, which have not been fully developed. Regarding the development and evolution of B2B in the next 1 to 2 years, there are the following eight predictions: (1)B2B websites will show a "one-sided" pattern of giants dominating the world. The geometric nature of revenue growth determines that the first website to achieve sufficient scale and mobility will be larger than even B2C consumer portals or retail giants; And even if the latecomers can be ranked second, the effect in this respect will be greatly reduced. (2) It is difficult for industry B2B websites to diversify from the industry. Such sites can only compete in a specific industry or field, and may make some progress in areas closely related to the industry they operate in, but it is difficult to penetrate other industries. (3) There will be a combination of industry and functional websites focusing on complementary advantages. Although industry websites have industry advantages, they lack functional expertise, while functional websites lack industry experience and customer relationships. The combination of the two can cross the gap between industry and functional websites to achieve complementary advantages. In such a combination, industry websites will mainly turn to customer relationship management. (4) Software vendors will break system platform boundaries. According to the different system platforms, the current software suppliers can be divided into three different camps: trading software suppliers (such as Ariba and CommerceOne), auction software suppliers (such as Moai and OpenSite) and trading platform suppliers (such as Broadvison). This pattern of fragmentation will be broken by the emergence of mergers and acquisitions among software vendors. (5) The transactional model will add derivative services. The current trading model is still limited to the spot market, and with the increase in the number of customers and the increasing familiarity with the market and the improvement of software platforms in terms of functions, this type of trading is expected to provide derivative services such as futures and freight yards. (6) Except for large enterprises, the centralized model will be abandoned. The early B2B business software model of centralizing catalogs, auctions, and transactions on a standalone basis will give way to a model focused on B2B websites. (7) A new type of superweb (ASP) that provides infrastructure and service sharing will emerge. Although it is difficult for industry websites to overcome industry barriers, this does not mean that they can only use independent infrastructure and service support, new websites that provide shared back-office systems and functional websites (ASP) that serve different industry websites in the form of rental are expected to become popular in the near 1 to 2 years. (8) Traditional commodity exchanges will be swallowed up. Not only do commodity exchanges lack consistency, they have difficulty integrating powerful trading capabilities to match B2B sites, and they lack business processing integration capabilities, and eventually the traditional commodity trading territory will be swallowed up by B2B sites." "Dinosaurs in the Age of e" will be the best interpretation of the traditional Commodity Exchange.
