Description

 Online commodity bargaining method and system

Technical field

 The present invention relates to an online bargaining method and system, and more particularly to an online commodity bargaining method and system in which a plurality of traders participate in a bid auction. Background technique

 With the maturity of Internet technology and information technology, the scale of the Internet has been expanding, and the number of network users has increased rapidly. The Internet has been applied to all walks of life in society, and is closely related to people's daily work and life. Online auction refers to an auction method that simulates the traditional field auction process on the Internet and realizes bidding and closing transactions through the network form. The essence is still to focus on price competition, establish exchange and interaction mechanisms between buyers and sellers, and jointly determine the transaction price and quantity of goods, so as to achieve a balanced market economy process.

 In an online auction, the auctioneer establishes trading rules and agreements for the owner of the auction website, and the specific auction activity is usually controlled by the seller himself using various auction functions provided by the website, such as setting the auction end time, auction reserve price, and auction. Starting price and so on. Online auctions also include new ideas such as system proxy bids, markups, “Buy It Now”, credit ratings, additional trading opportunities, and third-party payments.

 For example, the entire business model of Chinese e-commerce company Taobao and the US e-commerce company EBAY is based on online auctions. Online English auctions are the most common form of online auctions, with multiple buyers participating in the auction, and those with higher prices compete. After the auction deadline, the system closes the auction function, and the highest bidder gets the auction and pays at the highest price.

 However, the form of this auction has the following disadvantages:

 (1) Set a longer trading time, reduce transaction efficiency, and increase e-commerce costs.

Usually, the auctioneer has to set a longer trading time in order to attract more bidders to ensure the maximum utility. Usually, the auction time set by the seller will be close to the maximum allowable time allowed by the website; In order to guarantee the winning of the goods, the bidders have to pay attention to the transaction at any time to adopt the appropriate strategy. In this way, too long auction time will bring additional costs to buyers and sellers, and it does not effectively reflect the convenience and efficiency of online transactions, especially for perishable and easy-value products with high time characteristics, such as food and electronic products. As well as goods with high storage costs, etc.; in addition, the auction time is too long, and the customer will be less satisfied because they cannot get the goods quickly.

 (2) It is easy to breed problems such as "under the net", "malicious quotation", "sniper", "winner curse", etc., resulting in unfair competition and reduced user satisfaction.

 Since the essence of online one-way auction is still one-way auction, it will inevitably lead to problems such as "conspiracy" and "winner curse". In addition, due to the network characteristics of online one-way auction, it is easy to have an uncontrollable "sniper". "Hand" phenomenon, which is unfair to most unprofessional Internet users, reduces the satisfaction of most network users on online transactions, and has a certain hindrance to the promotion of the entire e-commerce.

 In addition, the entire business model of the US e-commerce company Pricel ine. com is based on the reverse auction model. The reverse bidding is dominated by the buyer. The buyer gives a detailed specification of the goods to be purchased. The bidders are bidding in turn, the price is getting lower and lower, and finally the lower bidder wins the bid, and the direct beneficiary is the buyer. Pricel ine. com also has sellers to lower the price every other cycle until the first bidder bids to reverse the auction mode. This mode is more suitable for time-sensitive, easy to change, depreciating goods such as concert tickets, Tickets, etc. However, this reverse auction is not conducive to the implementation of the buyer's strategic procurement and the effective formation of the supply chain, and can not effectively monitor the seller's credit and past performance.

 Embodiment 1

 An embodiment of the present invention provides an online commodity bargaining method. Referring to FIG. 1, FIG. 1 is a flowchart of an online commodity bargaining method according to an embodiment of the present invention. As shown in the figure, the online commodity bargaining method includes: Step 110: Receiving The selling price of the goods transmitted by at least one seller;

 Step 120: Receive a purchase price of the commodity transmitted by at least one buyer;

 The above steps 110 and 120 may be performed in no particular order, and the two may be performed simultaneously, which are two processes that do not interfere with each other. At least one seller or buyer, log in to the server, find the item that they want to sell or purchase, and send the price of the sale or the price of the purchase to the server under this item.
