Description

DIFFERENTIAL PRODUCT SALE SERVICE PROVIDING METHOD WITH MULTIPLE PURCHASING GROUPS CHARACTERIZED BY PURCHASING PRICE SUGGESTED BY CONSUMERS}

The present invention relates to a method for providing a product sale service, and more particularly, to a method for providing a differential product sale service for classifying a purchase group according to a purchase desired price proposed by a buyer.

The most fundamental starting point for a market economy is the price, determined by supply and demand. In providing any type or intangible product or service, the supplier seeks to profit by selling the product at a price that is higher than the cost of producing (providing) the product (service), and the consumer at the lowest possible price And to receive services. As a result, the selling price of the commodity is determined at the point of satisfying the buyer and the supplier. Even if the selling price is determined, the selling price changes again as various variables of the market such as demand and supply change. The market is functioning in a stable state by determining a new selling price at a point in the environment that can satisfy both the consumer and the supplier.

The basic concept of the microeconomic market economy is an auction as an example of a system where a consumer can directly experience in the field. In an auction, one or a few commodities are bidding for a desired price as many buyers compete, and only one or a few of the bidders who bid the highest price can finally win the purchase. . That is, in auction-based trading, for a limited supply, only one or a few buyers will be satisfied, and the other buyers, unfortunately, hope to be chosen as the winners at the next opportunity.

On the other hand, another example showing the pricing process of the market economy, such as reverse auction (reverse auction) is carried out in the same manner as the auction by changing the position of the seller and the consumer. In reverse auction transactions, sellers bid on goods or services they offer at the lowest possible price, and the consumer sells the goods and services while closing the deal with one or a few sellers who submit the lowest price among them. The price is determined. As described above, in the auction or reverse auction transaction, the buyer or seller participating in the auction has the advantage of closing the deal at a price desired by the buyer.

However, in spite of these advantages, the auction or reverse auction method has a problem in that a large number of trade participants participate in the pricing process, but only one or a few transactions are finally made. However, this problem is also somewhat solved as the Internet technology is developed. As the consumer's access to auction or reverse auction sales increases, B2C (Business to Consumer) e-commerce of auction or reverse auction is activated. You can check it through

On the other hand, the development of Internet technology has also greatly influenced the seller's strategy of determining the selling price of a product or service, and as a result, the seller has a practice of selling a product at a single price for a certain product. In addition, it is possible to determine the selling price of the product differently according to various variables of the market such as the selling time of the product, the buying pattern of the consumer, and the purchasing history. One of the successful pricing strategies in such a situation is a sales strategy that varies in selling price for each selling time, which is applied in an industry that sells air tickets or hotel accommodation tickets.

However, in contrast to the fact that price differential strategies over time have gained a favorable response in the market, the strategy of selling products at different prices according to the consumer's purchasing pattern and purchase history has not yet responded to the market. Selling strategies in which a seller sells the same product at different prices for each consumer are likely to undermine the fairness and norm of the price that the consumer perceives. This problem can be found in several marketing studies, such as the article entitled “Dynamic Pricing and Consumer Fairness” by Haws et al., Published in the December 2006 Journal of Consumer Research, Vol. 33, pages 304-311. That is, consumers feel that auction or reverse auction pricing methods are more equitable than the sellers unilaterally determine and present differential prices. However, as discussed above, auction or reverse auction has a limit that the number of final successful bidding is limited. Therefore, each product can be sold at a different price, without compromising the price norm (or perception of fairness) of the price of the consumer, and at the same time, it is possible to enter into a transaction without restriction on the number of trading participants who participate in the transaction. New pricing methods are needed.

The present invention has been proposed to solve the above problems of the existing proposed methods, according to the distribution of the purchase price suggested by the buyer to divide the buyer into at least two or more purchase groups at different prices for each purchase group Selling the product, but for the highest purchase group to which the buyer with the highest desired purchase price belongs, sell the product at the purchase price suggested by each buyer, and presenting a price lower than the highest purchasing group in the distribution of the desired purchase price. By allowing sellers to sell products at the desired discount rate suggested by the seller, the buyer can actively determine the purchase price, improving the buyer's price satisfaction, and the seller can also sell the product at the desired price. Reduce the burden, It is an object of the present invention to provide a method for providing a differentiated merchandise selling service that distinguishes a purchasing group according to a purchase price proposed by a buyer, which can conclude a transaction without limitation for the buyer.

In addition, the present invention, even if the buyer directly participates in the selling price determination process of the product, even if the same product is sold at different prices according to the buyer, without compromising the fairness of the pricing process recognized by the buyer, Another object is to provide a method for providing a differential merchandise selling service which can be classified according to a desired purchase price proposed by a buyer.

In addition, the present invention, if the seller satisfies certain requirements, by entering into a deal with all buyers participating in the purchase, the buyer's proposed purchase that can increase the buyer's participation to promote the seller's sale of goods It is another object of the present invention to provide a method of providing a differential merchandise selling service that classifies a purchasing group according to a desired price.

2 is a diagram illustrating a flow of a method of providing a differential merchandise selling service for dividing a purchase group according to a desired purchase price proposed by a buyer according to an embodiment of the present invention. As shown in Figure 2, the differential product sales service providing method for classifying the purchase group according to the purchase price proposed by the buyer according to an embodiment of the present invention, the step of receiving a product set from the seller (S100) Providing product information to the purchaser's terminal (S200), receiving a desired purchase price from the purchaser and participating in the purchase of the product (S300), if a sale restriction is satisfied, signing a purchase contract (S400), Determining a reference price and classifying the buyer into one of the purchasing group (S500) and granting the right to purchase a product having a discount rate applied according to the purchasing group (S600), and establishing a purchase contract to the buyer. The method may further include transmitting at least one of a message, a reference price, a purchase group to which the buyer belongs, and a sale price of the product (S700). have.

In operation S100, the service providing server 200 may receive the product information, the desired discount rate, and the sale restrictions of the sale product from the seller. Products sold using the present invention may be in various forms, such as services, gift certificates, coupons, as well as general goods, the seller may set various items related to the sale of goods and products using the seller terminal (100). The desired discount rate (D%) is a degree that the seller intends to sell the product at a discount rate, and may be 0% or more and 100% or less. On the other hand, in step S100, before the service providing server 200 provides a product from the seller terminal 100, the seller to notify the buyer, the original selling price (P) before the discount sale is applied, the buyer can present The minimum selling price, that is, the lower limit (E) of the desired purchase price that can be entered by the buyer may be set.

Meanwhile, the sale restriction received by the service providing server 200 in step S100 may include at least one of a discount sale time of a product, a minimum sale price (E) that can be sold, a maximum number of people who can purchase a discount, and a minimum number of people who can purchase a discount. It may include. In other words, the sale restrictions mean various matters applied to the discount sale, and if the sale restrictions are satisfied, the purchase can be made.

Among the restrictions on the sale, the time when the discount is applied may be designated as a predetermined time such as 1 day or 12 hours, but may be designated as “until the number of buyers exceeds the maximum number of people”. In addition, the sale restrictions may include items requiring payment at the same time as the completion of the sale contract or within a predetermined period. In this case, the payment method may include a variety of payment methods commonly used, such as credit card, account transfer, real time automatic transfer, mobile payment, mobile phone micropayment, payment using various points.

In operation S200, the service providing server 200 may provide product information to the purchaser terminal 300. The purchaser may determine whether to purchase the product by receiving and confirming various product information using the purchaser terminal 300. In this case, the service providing server 200 may assist the purchaser in determining whether to purchase a product by further providing a sale restriction to the purchaser terminal 300. The product information provided to the purchaser terminal 300 in step S200 may include various information such as a product name, a product image, a product video, and a method of using the product. The service providing server 200 may perform step S200 through a web page provided by the service providing server 200, but may provide various social media including social network services (SNS) such as Twitter and Facebook. You can also do

In operation S300, the service providing server 200 may receive a desired purchase price S from the buyer, and participate in the purchase of the product. The desired purchase price S that can be input from the buyer may be equal to or greater than the minimum selling price E set by the seller or less than the original selling price P, but may be freely inputted from the buyer. However, the seller sets the desired purchase price S in advance in step S100 to 10 won, 100 won, 1000 won, etc., so that the desired purchase price S input from the plurality of buyers becomes too dense and complicated. You can stop it. In operation S300, the service providing server 200 receives a purchase request price S from the buyer, so that the buyer may participate in the purchase of the product.

In operation S400, the service providing server 200 may conclude a purchase contract when the sale restrictions are satisfied. That is, if the sale restriction set by the seller is satisfied, such as when the discount sale time set by the seller in step S100 passes, or the purchaser participating in the purchase is less than the maximum number of persons who can purchase the discount and more than the minimum number of persons who can purchase the discount, the service is provided. The server 200 may conclude a purchase contract by entering into a purchase contract. When the contract is completed, the buyers participating in the purchase may be converted into a state in which payment is possible.

In step S500, the service providing server 200 determines the reference price (M) from the distribution of the desired purchase price (S), and is divided based on the reference price (M) according to the desired purchase price (S) entered by the buyer. A buyer can be classified into any one of two or more purchasing groups. That is, in step S500, the buyers may be divided into two or more purchasing groups by using the reference price M determined from the distribution of the desired purchase price S input from the plurality of buyers. In this case, the reference price (M) may be a representative value of the desired purchase price (S) distribution, and in particular, may be at least one of various representative values such as a median, a mean or average, and a mode. Can be. In addition, when classifying a purchase group, the purchase group may be divided into a purchase group of more than or greater than the reference price or a purchase group of less than or less than the reference price, depending on whether the reference price is included. That is, the reference price (M) is determined to distinguish the purchase group in step S600, which will be described later. If the purchase group is two, the reference price (M) will be one, but if the purchase group is three, the reference price (M) is It can be two. On the other hand, step S500 may be performed simultaneously in time with the purchase contract conclusion of step S400. Hereinafter, the distribution and reference price of the desired purchase price input from the buyer will be described in more detail.

Among various probability distributions that a random variable can have, a normal distribution expressed as [Equation 1] is proposed by de Moivre, Gauss, Laplace, etc. Probability distribution, which is the most basic and important probability distribution in statistics.

[Equation 1]

Where x is a random variable, μ is a mean of the probability distribution, and σ ² is a variance of the probability distribution. In particular, Laplace and Lyapunov confirmed the importance of the normal distribution by proving the Central Limit Theorem. The central limit theorem means that the sample mean extracted from any independent population is In other words, if the sample size is large enough, the proposition is close to the normal distribution regardless of the distribution of the population. Therefore, when applying the central limit theorem to the present invention, it can be expected that the distribution of the desired purchase price input from the buyer in step S300 becomes closer to the normal distribution as the number of buyers participating in the purchase increases.

3 illustrates an example of a distribution form of a purchase price input by a buyer in step S300 of a method for providing differential product sales service for classifying purchase groups according to a purchase price suggested by a buyer according to an embodiment of the present invention. One drawing. As shown in Figure 3, the distribution of the purchase price desired by the buyer in step S300 of the differential product sales service providing method for classifying the purchase group according to the purchase price proposed by the buyer according to an embodiment of the present invention The shape may be closer to the normal distribution as the number of buyers participating in the purchase becomes larger. In FIG. 3, when a normal selling price is 100,000 won, as a result of receiving a purchase request price from a buyer in a price range larger than at least 10,000 won from the buyer, the average is 50,000 won and the price distribution has a form close to a normal distribution. The figure was shown.

On the other hand, in step S500, the purchase group can be divided into two groups based on the reference price with respect to the distribution of the desired purchase price input from the buyer. In this case, the reference price may be a representative value such as an average and a mode, but may be set to a median value in consideration of the number of buyers participating in the purchase.

4 is an example of dividing a purchase group into two groups according to a distribution of a desired purchase price in step S500 of a method of providing a differential product selling service for classifying purchase groups according to a purchase price suggested by a buyer according to an embodiment of the present invention. It is a figure which shows. In FIG. 4, based on the median, that is, the purchase price suggested by the buyer corresponding to the top 50%, of KRW 60,000, the purchase group is divided into the upper purchase group and the lower purchase group. Has been shown.

According to an embodiment of the present invention, in step S500, the purchase group may be divided into three groups based on the reference price with respect to the distribution of the desired purchase price input from the buyer, wherein the reference prices are two, respectively, higher 33%, top 66% and so on. That is, when dividing the purchasing group into three, one reference price may be distributed between the median of the distribution of the desired purchase price and the highest desired purchase price, and the other reference price is the desired purchase. It can be distributed between the median of the distribution of prices and the lowest desired purchase price.

5 is divided into three groups according to the distribution of the desired purchase price in step S500 of the differential product sales service providing method for classifying the purchase group according to the purchase price suggested by the buyer according to an embodiment of the present invention An example is shown. In FIG. 5, the purchase price is 70,000 won, which is suggested by the top 33% of buyers, and 30,000 won, which is the price suggested by the top 66% of buyers. Results are shown in which the cohort is divided into a top purchase group, a middle purchase group, and a bottom purchase group.

In operation S600, the service providing server 200 may grant the buyer the product purchase right to which the discount rate is differentially applied according to the purchase group to which the buyer belongs. Preferably, the purchase group to which the purchaser who inputs the desired purchase price which is the highest belongs belongs may be given a right to purchase a product to purchase the product at the purchase desired price. In other words, if the desired price is entered too high, the product is purchased at that price, so that the buyer cannot unconditionally suggest a high price. In addition, according to an embodiment, when the purchase group is divided into two in step S500, a desired discount rate (D%) set by the seller in step S100 for the lower purchase group to which the buyer who inputs the lowest desired purchase price belongs. This can give the right to purchase the applied product. In this case, if the buyer suggests a price that is too low, it may result in the purchase of the product at the price set by the seller rather than the price suggested by the buyer. You can make tens of thousands. In other words, the buyer may not be able to present the desired price for purchase unconditionally high or unconditionally, so that the distribution of the desired price for purchase is formed at an appropriate price line. For example, as shown in FIG. 4, when the purchasing group is divided into a higher purchasing group and a lower purchasing group, the upper purchasing group is granted a right to purchase a product at a desired price range, and the lower purchasing group is a seller. A desired discount rate, for example, a right to purchase a product to which a 10% discount rate is applied can be granted. Therefore, buyers belonging to the upper purchasing group can purchase products at the price suggested by the buyer, and price satisfaction is improved, and sellers of the lower purchasing group reduce the price burden of the seller by selling the products at the price set by the seller. Can be.

As another embodiment of the present invention, even if the purchase group is divided into three groups based on two reference prices with respect to the distribution of the purchase price, the higher purchase group to which the buyer who inputs the highest purchase price belongs is included. In this regard, it is possible to grant a product purchase right to purchase a product at a desired purchase price. In addition, according to the embodiment, the product purchases to which the desired discount rate (D%) set by the seller is applied to a purchase group located between two reference prices or to a purchase group to which the buyer who inputs the lowest desired purchase price belongs. You can grant rights. In this case, too, the buyer cannot unconditionally present the desired purchase price higher or lower unconditionally, so that the distribution of the desired purchase price can be formed at an appropriate price line. For example, as shown in FIG. 5, when a purchasing group is divided into a higher purchasing group, a middle purchasing group, and a lower purchasing group, the upper purchasing group is granted the right to purchase a product at a desired purchase price, and the intermediate purchasing group. The group may be granted a right to purchase a product with a desired discount rate (D%) set by the seller, and the lower purchase group may be granted a right to purchase a product with a discount rate lower than the desired discount rate (D%) set by the seller. That is, according to an embodiment of the present invention, the right to purchase a product having a lower discount rate is applied to the lower purchase group to which the buyer who has entered the lowest desired purchase price belongs to the middle purchase group located between two reference prices. You can give it.

In operation S700, the service providing server 200 may transmit a purchase contract establishment message, a reference price M, a purchase group to which the buyer belongs, and a discount rate of the product to the buyer. Steps S400 to S600 described above can be performed at about the same time in time, and step S700 is to notify the purchaser of the result of performing steps S400 to S600. In particular, the right to purchase goods in step S600 may be granted to the buyer by transmitting a certificate or the like to the buyer terminal 300 through the network, and may include transmission by printing, printing or mailing on the buyer terminal 300 screen. .

The present invention may be embodied in many other specific forms without departing from the spirit or essential characteristics of the invention.
