[0018] 1. Fixed price method; public auction or price-increasing auction: both forms are seller-driven, and the buyer cannot identify the seller
Either at the price determined by the seller, or at a price higher than the buyer's expectation; in many cases, it is difficult for buyers and sellers to negotiate efficiently on price and other transaction conditions, and information
asymmetry is serious
[0019] 2. Reverse Auction (Reverse Auction): It is buyer-driven. For ordinary individual consumers (or
purchasing companies), because they are in a weak position in market information, it is difficult to realize the information screening of sellers. The market price and its
product characteristics cannot be well and accurately grasped, and it is difficult to accurately give bidding information such as the expected purchase price of a specific commodity, which is at a
disadvantage in commodity transactions, so it cannot protect the interests of consumers to the greatest extent. This reduces the enthusiasm of consumers to buy; moreover, this form must first have a large number of purchase items, so the operation is more difficult and it is not easy to make a deal
[0025] In most cases, the platform side directly organizes or participates in product sales and direct management of transactions, which hinders the development of the platform itself and cannot provide better services to users, which violates the essential requirements of e-commerce development; it also makes
transaction management rigid, and users Lack of necessary flexibility and
operability in the various stages of transaction release, transaction condition maintenance and modification, and transaction termination. Direct self-service management and operation of transaction release and termination cannot be realized. Buyers and sellers cannot timely conduct information on transaction conditions and other information according to market changes. Online maintenance and modification cannot realize real-time dynamic tracking of the transaction status, so that the expected transaction conditions or purchase requirements cannot be dynamically set;
[0026] Lack of effective
information transmission, screening or communication mechanisms, poor interaction between buyers and sellers, and serious information
asymmetry; poor communication between buyers who are or are about to participate in ordering the same product;
[0027] Neither of these two forms can satisfy some buyers with
special needs. For example, some buyers are willing to purchase goods in advance at a slightly higher price, or some buyers are willing to wait to buy goods at a slightly lower price; or , if the transaction cannot be completed in this cycle, willing to keep your order automatically valid in the next cycle;
[0028] These two forms also cannot meet more needs of sellers, and cannot implement differential pricing strategies for different buyers to earn more profits. The product sales cycle is rigid, and any product must be sold at the end of the agreed sales cycle. Slow down the seller's product sales and capital turnover progress, reducing sales profits;
[0029] The second form deals with a relatively high target price for all purchases that exceed the target purchase volume, which cannot maximize the protection of the buyer's interests and reduces the buyer's enthusiasm for purchase to a certain extent;
[0030] As for the third form represented by the cloud network online
group buying http: / / www.cbuy.com.cn / operated by Beijing Cloud Network Unlimited Network Technology Co., Ltd., it cannot actually be realized at all, because the final
transaction price of the commodity is actually It is calculated based on the total purchase volume of all registered buyers, and among these buyers, those whose bid (expected price) is lower than the final
transaction price cannot conclude a transaction, so the total purchase volume of the final transaction must be less than the corresponding final
transaction price. The purchase volume required by the seller
