Description

Technical Field [0001] The present invention relates to a commodity trading apparatus and a commodity trading apparatus that apply a dynamic commission,

The present invention relates to a commodity trading technique, a commodity trading device for calculating a commodity that is dynamically changed by a transaction volume and a transaction price of a commodity, processing a settlement of a buyer including the commodity, ≪ / RTI >

The online trading market is becoming more active. Online transactions that can buy and sell not only real goods but also virtual goods such as game items online are increasing.

Among them, the online transaction market where users become dealers or buyers are increasing. For example, in online sites such as "Used Country "," Chubpu ", transactions for user's products are increasing. The seller who sells the product can freely register the sale price of the new product or the used product, and the purchaser who purchases the product can apply for the purchase of the transaction and pay the purchase price corresponding to the selling price of the seller After receiving the merchandise of the seller. Here, the service provider providing the online transaction service to the seller and the purchaser imposes the commission fee on the buyer.

Especially, the service provider providing the service of the commodity transaction among the users takes the profit model in the form of taking the charge of the free or the fee. In the case of paid fees, the service provider generally applies a fixed fee rate for all or part of the goods.

One of the most important factors in transactions between users is speediness. By promptness, the seller and the buyer must conclude the transaction promptly. If there are no products or the price is unsatisfactory, the promptness of the transaction is not guaranteed and the transaction is delayed. If there is no commodity, it is a force majeure factor, but if the price is unsatisfactory, the price will change for the promptness of the transaction. For example, prices are falling for the sake of quick trading. Assuming that commodity prices fall along with commodity prices, the speed of transactions can be further assured.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

1 is a schematic block diagram of a commodity trading system 1 according to an embodiment of the present invention.

The commodity trading system 1 according to an embodiment of the present invention is constructed based on a wired and wireless network and includes a plurality of commodities that provide online transaction services for commodities to user terminals 3 connected to the commerce site 200 A transaction server 2 and a user terminal 3. [

The wired and wireless networks in the present invention typically include all communication networks capable of data communication using various protocols such as a mobile communication network, a wired and wireless public network such as the Internet, and a private network.

The commodity trading server 2 is a commodity trading apparatus provided by the present invention and provides an online transaction service for a commodity to a user terminal 3 connected to a transaction site 200. [ The product does not have special restrictions such as a physical product or a virtual product. That is, the user may trade new goods, used goods, online coupons, vouchers, and the like.

Here, the commodity trading server 2 imposes a predetermined fee each time a commodity transaction is concluded through the transaction site 200. [ The commission corresponds to a fee for the online transaction service charged by the commodity trading server 2 to the users. The commission information is displayed for each individual commodity transaction through the transaction site 200, and the commodity price including the commission is paid by the purchaser when the commodity is concluded. The commodity trading server 2 updates the commission for each individual transaction at a predetermined cycle. The commodity trading server (2) does not apply the fixed commissions collectively but calculates the commission that fluctuates every cycle and applies the commission to each transaction of the individual commodities.

Preferably, the commodity trading server 2 determines the commission rate so that the transaction can be concluded promptly for the same commodity transaction. In order to determine the commission rate, the commodity trading server 2 collects the commodity trading volume information. The commodity transaction server 2 can apply a low commission rate when the promptness of the transaction is hindered due to the low volume of the commodity because the promptness of the commodity contract is increased if the price of the commodity is lowered due to the characteristics of the commodity.

The user terminal 3 is not limited to a computer terminal, a mobile terminal, or the like, provided that the user terminal 3 can access a website through an Internet connection. The user becomes a seller and can register a commodity on the transaction site 200, becomes a purchaser, and can purchase a commodity on the transaction site 200. [

Here, the user terminal 3 may be provided with a dedicated application for receiving the online transaction service through the transaction site 200. For example, in the case of a mobile terminal, it is possible to use the online transaction service by accessing the transaction site 200 through a web browser, and it is possible to use the online transaction service through execution of the application.

2 is a schematic internal structure diagram of the goods transaction server 2 of Fig. FIG. 3 is a schematic internal structure diagram of a goods transaction server 2 according to another embodiment of the present invention. Hereinafter, the goods transaction server 2 will be described with reference to FIGS. 2 and 3. FIG.

The commodity trading server 2 according to an embodiment of the present invention includes a trading volume collecting unit 21 for collecting a transaction amount for each commodity to be online traded, a ranking calculating unit 22 for calculating a commodity ranking of the collected trading volume, And a transaction concatenation unit 24 for concluding a transaction when the settlement process is successful for the settlement amount of the buyer including the calculated fee and the fee calculated by the commission calculation unit 23 for calculating the commission corresponding to the fee.

The transaction amount collection unit 21 collects transaction amount information for the same goods. The amount of transaction information to be collected includes at least one of the number of sales registration of products, the number of purchase registration, and the number of transactions.

The ranking calculation unit 22 calculates a higher ranking based on the collected transaction amount as the transaction amount increases. For example, the first place with the highest trading volume is ranked first in the highest ranking.

Preferably, when the ranking calculating section 22 calculates the ranking by using a plurality of pieces of the sales registration number, the number of purchase registration, and the number of the transaction completion pieces of goods collected by the transaction amount collecting section 21 as the transaction amount information, Calculate the average of trading volume information. Appropriate averaging methods such as arithmetic averaging and weighted averaging can be applied to the averaging method, and there is no particular limitation. The ranking calculating section 22 calculates a higher rank as the calculated average value is larger.

Here, the weight may be applied when calculating the average. For example, in order to speed up the transaction, a weighted average value of the trading volume can be calculated by assigning a predetermined weight to the number of transaction concludes> sales registration> number of purchase registrations in order. For reference, the fastest of transactions and the number of transactions are the most relevant, so the largest weight can be applied. Also, the second largest weight can be applied to the number of sales registrations, since it is determined that the supply of the commodity is more related to the promptness of the transaction than the demand of the number of purchase registrations.

The commission calculation section 23 calculates a higher commission rate as the calculated ranking of the commodity-related transaction amount increases, and calculates the commission rate by multiplying the calculated commission rate by the selling price of the seller and the purchase price of the purchaser. Of course, the highest commission rate is determined for the first rank product. The commission calculating section 23 updates the calculated commission for each commodity page of the seller and the purchaser corresponding to the commodity. That is, the users viewing the sales page or the purchase page can inquire the purchase / sale after viewing the payment amount including the sales price / purchase price and the commission fee.

Here, the dynamic calculation of the fee commensurate with the transaction amount is intended to provide promptness of the transaction. For example, when the amount of transactions is large, commodity trading takes place actively, so that the commission calculation section 23 can set a high commission. On the other hand, if the transaction amount is small, the promptness is not guaranteed due to the delay of the transaction, so that the fee calculation section 23 lowers the commission to encourage the buyer's purchase, thereby assuring the promptness.

Furthermore, the ranking calculating section 22 and the fee calculating section 23 can perform processing corresponding to each predetermined period. The predetermined period can be a unit of time, day, week, month, and the like. For example, when the daily cycle is set, the ranking calculating section 22 calculates the ranking based on the day before day trading volume, and the fee calculating section 23 determines the commission rate based on the calculated ranking. On the other hand, execution processing using the above-described period may be replaced with real-time processing. In other words, the ranking calculating section 22 and the fee calculating section 23 can perform calculation of ranking and fee in real time using the most recent transactions.

The transaction concatenation unit 24 concludes the transaction by accepting the transaction or automatically matching the counterparty. The terms of the transaction are that the purchase becomes> = sale and the settlement of the payment including the fee is completed by the buyer. The transaction concatenation unit 24 processes the payment for the payment amount of the purchaser, and ends the transaction when the process is successful. That is, when the settlement amount is paid by the purchaser, the transaction is concluded, and the merchandise of the seller is delivered to the purchaser through online or offline, and becomes the ownership of the purchaser.

In the case of the transaction acceptance of the other party, the transaction concluding unit 24 receives the fact that the seller views the purchase page of the buyer and then submits the purchase of the goods to the buyer. Of course, the transaction concluding unit 24 can receive the purchase acceptance of the commodity by registering the purchase price beyond the selling price of the seller after the purchaser views the seller's sales page, and can perform the settlement processing of the purchaser.

In the case of the automatic matching, the transaction concluding unit 24 concludes the transaction by matching the sales item with the purchase item on the condition of the registered sales application and the purchase application, on the condition that the seller's purchase price is abnormal. Here, when the difference is caused by the purchase price exceeding the selling price, the difference generated becomes the profit of the commodity transaction.

For example, assuming that the buyer has a purchase price of 2,000 won and the commission rate is 10% with respect to the seller's selling price of 1,000, the transaction concluding unit 24 concludes the sale and purchase order, And a fee of 200 won. Then, the transaction contracting unit 24 settles the 900 won, which is the sum of the seller's commission of 100 won and the settlement amount of 2,200 won, to the sales price of the seller, and the remaining 1000 won (purchase price-sales price) +100 won (seller commission) +200 The sum of the won (commission fee) is 1,300 won.

Here, according to the service policy, the transaction concluding unit 24 may hold the payment information of the prepaid purchaser in advance, and may automatically complete the settlement process upon concluding the transaction. At the time of prepayment, the purchaser can pay the commission in advance and avoid the later changed commission. In the case of automatic matching, the transaction concluding unit 24 may transmit the matched transaction information to the seller and the buyer, respectively, and request transaction approval. The seller registers the transaction approval, and the buyer registers the transaction approval by completing the payment.

Here, the transaction concluding unit 24 may conclude the transaction with the burden of at least one of the seller and the purchaser. For example, it is possible to charge commodity fees only to either the seller or the buyer.

In addition, the transaction concatenation unit 24 may apply various priorities to speed up the transaction based on the automatic matching service policy. For example, when the 'time priority' is applied, the transaction concluding unit 24 selects the buyer in the order of the first purchase request among the purchase application amounts larger than the payment amount added to the seller's price, . As another example, when the 'amount priority' is applied, the transaction concluding unit 24 selects a buyer having the smallest difference among the purchase application amounts larger than the settlement amount, and concludes the transaction with the seller. Of course, "time priority" + "amount priority" may be applied in parallel.

Referring to FIG. 3, there is shown another embodiment for calculating a commission based on a price (difference value) instead of an example of calculating a commission based on the transaction amount.

In another embodiment of the present invention, the commodity trading server 2 further includes a price collecting unit 211. Since the above description can be used for the ranking calculation section 22, the fee calculation section 23, and the transaction concatenation section 24, only differences will be described.

The price collecting unit 211 collects the sales price registered by the seller and the purchase price registered by the buyer with respect to the transaction of the goods.

Here, the ranking calculating section 22 obtains the difference between the average value of the sales price and the average value of the purchase price satisfying the transaction concluding condition " average purchasing price-average selling price " = 0 ", and the larger the difference value ) We rank high rank of goods. The difference value is the profit of the goods transaction server 2. Then, the commission rate and commission based on the rank are determined, and the transaction is concluded for the buyers whose purchase price of the buyer is higher than that of the seller. If the purchase price is less than the selling price, it is impossible to conclude the transaction. Therefore, the fee calculation section 23 calculates the minimum commission rate or the minimum commission to apply to the individual transaction case.

If the difference is large, the purchase price is high due to the excess or surplus of the demand due to the shortage of supply. Even if the commission is relatively high, it does not affect the promptness of the transaction. On the other hand, the smaller the difference value, the more convergence between supply and demand. If the commission is lowered, the promptness of the transaction can be increased by the demand inducement. In particular, if the purchase price is less than the selling price, the purchase price can be lowered with a minimum fee.

FIG. 4 is an example of a commodity transaction server 2 of FIG. 2 and FIG. 3 for calculating a commission, and FIG. 5 is an example of a completion rate table referenced by the commodity transaction server 2 of FIG. The following description will be made with reference to Figs. 4 and 5. Fig.

Referring to FIG. 4, the commodity trading server 2 of the present invention can calculate a commission based on a transaction amount or a price (difference value) according to another embodiment.

Furthermore, the commodity trading server 2 can calculate the commission in which the transaction amount and the price are applied in parallel. The higher the transaction volume and the larger the difference in price, the higher the ranking is determined, and the higher the ranking, the higher the commission rate can be calculated. At this time, each unique weight is applied to the transaction amount and the price, and the commission rate may be calculated by an average calculation formula. Then, the commission rate of the present invention becomes larger as at least one of the transaction amount and the difference value becomes larger. The commission increases as the commission rate and sales price increase.

Referring to FIG. 5, the ranking calculation unit 22 sorts the collected transaction volumes by product and ranks the products according to the order in which the transaction volume is large. The commission calculation unit 23 can inquire the commission rate from the commission rate table 230 with the above rank as a key. The commission rate table 230 corresponds to the commission rate DB of the present invention.

On the other hand, the fee calculation unit 23 may calculate the commission rate by a calculation method based on a unique calculation formula instead of the inquiry method inquiring the commission rate from the commission rate table 230. For example, the calculation of the ranking can be omitted and the commission rate can be calculated through the calculation formula using the total trading volume as a denominator and the commodity trading volume as a numerator by the 'calculation method'.

Further, a maximum value may be applied to the commission rate or the fee in accordance with the service policy. For example, a commission rate or fee that exceeds a set maximum is replaced by a maximum commission rate or a maximum commission.

6 is a schematic flowchart of a commodity trading method according to an embodiment of the present invention.

The commodity trading server 2 provides an online transaction service for commodities to the user terminals 3 connected to the transaction site 200. By the online transaction service, the user becomes the seller and registers the commodity and the selling price. The sales information of the registered product is provided to the user terminal 3 of the buyers. In addition, the user becomes a purchaser and registers the goods and the purchase price. The purchase information of the registered goods is provided to the user terminal 3 of the seller. The seller or buyer can view the transaction application information of the other party and then accept the sale or purchase.

In the process of providing the online transaction service, the commodity trading server 2 collects at least one of the number of sales registration, the number of purchase registration, and the number of transactions concluded for each commodity as a commodity trading amount (S10).

When the transaction amount is collected, the commodity trading server 2 calculates a higher rank of the commodity as the transaction amount collected for each set renewal period is larger (S20).

Here, when the commodity trading server 2 collects a plurality of transactions among the number of sales registration, the number of purchase registration, and the number of transactions concluded in the step S10, an average is calculated for each collected transaction amount, High ranking. Weights may be applied to each transaction volume so that a weighted average can be calculated.

When the ranking of the transaction amount is calculated, the commodity trading server 2 calculates the commission according to the order (S30). The higher commission rate is multiplied by the selling price of the seller, and the commission is calculated. That is, the higher the rank, the higher the commission, and the commission is proportional to the commodity price. The commodity trading server 2 updates the calculated commission on the commodity page of the corresponding commodity.

Here, the commodity trading server 2 can inquire the commission rate from the commission rate DB by ranking the commodity trading server 2 according to the 'inquiry method'. In addition, the commodity trading server 2 may calculate the commission rate by omitting calculation of the rank of the step S20 in an arithmetic form based on the transaction amount according to the 'calculation method'.

For reference, the steps (S10) to (S30) may be performed in units of a predetermined period. Assuming that the cycle is day, the commission rate applied in today's cycle of n days is determined based on the trading volume calculated in yesterday's cycle corresponding to n-1 (n > = 2) days. Also, it is possible that the commission of the goods page currently being inquired by the real-time processing is dynamically generated and updated based on the latest transaction amount.

When the commission is calculated, the commodity trading server 2 calculates the purchase amount of the purchaser by applying the fee calculated at the seller's price and the purchase price of the purchaser, respectively, and concludes the transaction of the purchaser who paid the purchase amount (S40). Of course, the terms of the transaction are that the sale is <= purchase price, and payment of the payment amount including the fee is completed by the buyer.

Here, when the user accepts the purchase application of the commodity or the application for sale of the commodity, the commodity trading server 2 handles the conclusion of the transaction. In addition, the commodity trading server 2 can automatically process the sales of the seller and the purchase of the purchaser to process the transaction. The commodity trading server 2 concludes a transaction between the seller and the buyer by applying at least one ranking method among 'time priority' and 'amount priority'.

Meanwhile, according to another embodiment of the present invention, in step S10, the goods transaction server 2 collects the sales price of the seller and the purchase price of the buyer for each product. In step S20, the commodity transaction server obtains the average value of the collected sales price and purchase price, calculates the difference value by subtracting the average value of the selling price from the average value of the purchase price, and calculates the commission rate by calculating the commission rate according to the calculated difference value. Subsequent processing is the processing of steps S30 and S40.

Then, the commodity trading server 2 can be an embodiment in which the embodiment according to the transaction amount and the embodiment of the commodity price (the difference value between the selling price and the purchase price) are concurrently performed. That is, the commodity trading server 2 can estimate the commission by calculating the commission rate considering the transaction amount and the difference value.

In the above-described embodiment, the term "part" is not used to denote the hardware classification of the goods transaction server 2. Accordingly, a plurality of constituent parts may be integrated into one constituent part, and one constituent part may be divided into a plurality of constituent parts. The constituent unit may mean a constituent part of hardware, but may also mean a constituent part of software. Therefore, it should be understood that the present invention is not particularly limited by the term "part ".

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It goes without saying that various modifications and variations are possible within the scope of equivalence of the scope.
