Description

  The present invention relates to a joint investment auction system using a communication network.

  A conventionally known auction is a system in which a bidder registers and participates in an auction one by one for a product to be bid, and a person who has the highest price within a specified time can make a successful bid. Recently, the number of participants can participate from a terminal using a network technology such as the Internet.

Since the target products of the auction are often expensive, the auction participants solicit the joint investor after making a successful bid, obtain capital contribution on the condition of future resale profit and dividend allocation, and reduce the cost of the successful bid. It may be regained or profits such as membership fees and fees may be obtained from investors. In addition, in order to avoid the risk of funding due to the fact that joint investors do not gather after a successful bid, joint investors may be recruited at the time of bidding. In the latter case, there are many cases in which a joint investment solicitor and a joint investor consult in advance on the bid limit and so on, and the joint investment solicitor conducts bidding on behalf of them. However, the highest bid price frequently changes in auctions, and there are cases where it is not in time for bidding if consulting each time. Therefore, in an auction using network technology, a group is formed on the network between the joint investment solicitor and the joint investor, and the maximum bid price, the total investment amount of the entire group, and the joint investment solicitor / co-investor. A technology is disclosed that enables group members to confirm information such as each investment ratio from a terminal so that bids can be made quickly and easily (see Patent Document 1).
JP 2002-183510 A

  However, the bidding period of an auction is generally limited, and many bids are often made aiming at the limit of the bidding period, so objective and sufficient examination time may not be taken as the bid deadline approaches. Many. In addition, some auction products such as paintings, antiques and other art objects and real estate, etc., are always profitable by changing prices and reselling, and there is a possibility of generating new profits after growth like a racehorse. There is something. In the former case, the present value serves as a rough standard, but it is often difficult to objectively determine the present value. Furthermore, in the latter case, dividends are an important factor, making it more difficult to determine the bid price. However, in the past, it was not possible to bid while objectively evaluating such information on the present value and dividends.

  Even in such a case, it is highly possible that the bidding by an individual will prepare the necessary information in advance and make an appropriate bid. There is no guarantee that information is shared, and the possibility of acting appropriately as a group decreases. As a result, each participant who participates jointly has a risk of making a successful bid at an unreasonably high amount, or giving up on the way and missing an opportunity for a successful bid under favorable conditions. In addition, participants who seek joint participation cannot smoothly recruit participants and provide funds, so there are no opportunities for successful bids and their own risks are increasing.

  The present invention has been made based on such circumstances, and in a joint investment type auction system using a communication network, a system, a method, and the like that enable each member of the investor group to share appropriate bid support information. The purpose is to provide.

  The net auction system of the present invention is a net auction system having a plurality of terminals, a management server that can be connected to each of the terminals, and an auction site server that operates the net auction site and can be connected to the management server. Each participant's investment amount entered from one of the terminals by each participant who jointly participates in the bid for the specific product that was exhibited, and the highest bid price of the product recorded in the auction site server are sent to the management server The present invention relates to a net auction system in which participants are placed in a state where they can be viewed from each terminal and bids are jointly made by participants. In the present invention, the management server predicts an appropriate successful bid price of the product, stores the appropriate successful bid price in the storage device, and stores information on the appropriate successful bid price stored in the storage device in response to access from each terminal. Is in a state where it can be browsed from each terminal.

  For this reason, each participant who participates can participate in the bidding and the re-bidding that increased the investment amount while looking at objective information about the appropriate winning bid price, and whether or not to participate in the bidding. Whether or not to increase can be judged accurately by oneself.

  The management server may include a price prediction data input unit for predicting a proper successful bid price of a product and a prediction unit for predicting a proper successful bid price of a product based on the price prediction data.

  In addition, the management server may calculate the burden amount for each participant of the appropriate successful bid price based on the predicted appropriate successful bid price and the investment amount of each participant.

  According to the joint bidding method of the net auction of the present invention, the terminal transmits the investment amount of each participant input to the terminal by each participant who jointly participates in the bidding of a specific product exhibited in the net auction to the management server. A step in which the management server obtains the highest bid price of the product recorded in the auction site server from the auction site server that operates the net auction site; and the management server determines the investment amount and the highest bid price of each participant. And a step of placing the device in a state where it can be viewed from a terminal. The management server has a step of predicting an appropriate successful bid price of the product and placing the appropriate successful bid price in a state where it can be viewed from the terminal.

  The management server may include a step of acquiring price prediction data for predicting an appropriate successful bid price of the product, and a step of the management server predicting an appropriate successful bid price of the product based on the price prediction data.

  Further, the management server may include a step of calculating a burden amount for each participant of the appropriate successful bid price based on the predicted appropriate successful bid price and the investment amount of each participant.

  The management server of the present invention includes an investment amount receiving unit that receives, from a terminal, an investment amount of each participant that is input to the terminal by each participant who jointly participates in a bid for a specific product that has been exhibited in an online auction, The highest bid price receiving part that receives the highest bid price of the product recorded on the auction site server that operates the auction site from the auction site server, and the state that the participation amount and the highest bid price of each participant can be viewed from the terminal And a management server used in a network auction for bidding jointly. Then, the appropriate successful bid price of the product is predicted, the appropriate successful bid price is stored in the storage device, and the information on the appropriate successful bid price stored in the storage device is made available for browsing from the terminal in response to access from the terminal. It has a feature that a successful bid price prediction display unit is provided.

  The management server has a prediction data acquisition unit that acquires price prediction data for predicting a proper successful bid price of a product, and the appropriate successful bid price prediction display unit is based on the price prediction data acquired by the prediction data acquisition unit, You may make it predict the appropriate successful bid price of goods.

  Moreover, you may make it a proper successful bid price prediction display part calculate the burden amount according to the participant of an appropriate successful bid price based on the predicted proper successful bid price and the investment amount of each participant.

  The program of the present invention is a management server used in a network auction in which bids are made jointly, and each participant's investment amount input to the terminal by each participant who jointly participates in a bid for a specific product exhibited in the network auction. , Function as investment amount receiving means received from the terminal, function as the highest bid price receiving means received from the auction site server, the highest bid price of the product recorded in the auction site server operating the net auction site, The present invention relates to a program that functions as a display unit that puts a participant's investment amount and a highest bid price in a state where they can be viewed from terminals. Then, the management server is made to function as an appropriate successful bid price prediction display unit that predicts an appropriate successful bid price of a product and puts the appropriate successful bid price in a state that can be viewed from the terminal.

  The program of the present invention causes the management server to function as prediction data acquisition means for acquiring price prediction data for predicting an appropriate successful bid price of a product, and is acquired by the prediction data acquisition unit in the appropriate successful bid price prediction display means. You may comprise so that the appropriate successful bid price of goods may be estimated based on price prediction data.

  Moreover, you may make it calculate the burden amount according to the participant of an appropriate successful bid price based on the predicted appropriate successful bid price and the investment amount of each participant on the appropriate successful bid price prediction display unit.

  Thus, according to the auction system and the like of the present invention, each participating participant can participate in the bid while objectively evaluating information on the present value and the dividend, and at an unfair price. Avoid successful bids and increase opportunities for successful bids at reasonable prices. Participants seeking joint participation can also facilitate the recruitment of participants and the provision of funds by providing appropriate bidding support information to each participant. Risk can be reduced.

  The details of the jointly-funded auction system of the present invention will be described below with reference to the drawings. FIG. 1 shows an overall configuration diagram of an auction system according to the present invention. Participant terminal B held by participant b and participant terminals C1 and C2 held by participants c1 and c2 are connected to communication network 101 such as the Internet. In the figure, three participants and three participant terminals are displayed, and the following explanation is also based on this, but there is no limit on the number of participants and the number of terminals. A plurality of participants can also share one participant terminal. Participant b is a person who solicits and represents a joint investment in the auction, and participants c1 and c2 are persons who participate in the joint investment, but each participant becomes either by auction or product. sell. Hereinafter, a set of the participant b and the participants c1 and c2 is referred to as a participant group a, and the participant b and the participants c1 and c2 may be collectively referred to as members. As the participant terminal B and the participant terminals C1 and C2, a terminal having a communication function such as a mobile phone can be used in addition to a personal computer.

  Further connected to the communication network 101 is a management server S having a bid support database 1 that performs bid support for members and an auction site server AS that manages an auction site 102 that is a virtual auction site on the net. Yes.

  FIG. 2 shows an outline of a bid support database constructed in the management server S. The bid support database 1 is configured as a set of independent bid support data 1a, 1b, etc. for each auction product. Here, bid support data 1a for a specific product P on a specific auction site 102 is shown as a representative.

  The bid support data 1a includes auction site information 11 having the name and address of the auction site 102, bid information 12 of the product P, bid status information 13, bid support information 14, and price prediction information 15. is doing. The bid information 12 includes general information related to bidding such as the code number of the product P, product information, a bid period, bid conditions, and image data. The bid status information 13 includes other bidder names, bid prices for each bidder, and list data of bid dates and times. The bid status information 13 is periodically updated from the management server S by periodically accessing the auction site server AS.

  The bidding support information 14 includes information on the total investment amount 141, the appropriate successful bid price 142, and the expected dividend 143 of the entire participant group a. The appropriate successful bid price 142 is objectively calculated according to predetermined prediction data 15a, 15b (see FIG. 3) and 15e (see FIG. 5) of the price etc. prediction information 15 described below. The predicted payout 143 is, for example, a payout if the product P is a competitive horse, and is similarly objectively calculated according to predetermined prediction data 15c and 15d (see FIG. 4). The investment amount 144 by member is the investment amount of each member of the participant group a, and the total is the total investment amount 141. The investment ratio 145 is a ratio of the investment amount 144 by member to the total investment amount 141. For example, in the case of the participant c1, since the investment is 600,000 yen, the investment ratio 145 is 30%. Similarly, the appropriate successful bid price 146 for each member and the expected dividend 147 for each member are also proportionally distributed with the investment ratio 145. Note that the expected dividend 147 for each member does not necessarily need to be proportionally distributed at the investment ratio 145, and can be set as appropriate, for example, the higher the investment ratio, the higher the distribution ratio.

  In the price prediction information 15, appropriate prediction data is set according to the product P. Hereinafter, with reference to FIGS. 3 to 5, an example of typical price etc. prediction information 15 is shown by taking a racehorse and a picture as an example.

  FIG. 3 shows prediction data 15a and 15b used for predicting an appropriate successful bid price of a racehorse. These data are investigated and input when the participant b recruits joint investors, but the participants c1 and c2 may input or may be requested by a third party. Moreover, the member can select which of the prediction data 15a and 15b is used.

  In the prediction data 15a, the winning bid price and the winning bid year of each of the father horse and the mother horse are recorded. The actual price is a price corrected by the price fluctuation rate after the successful bid year. The weighting coefficient is for designating which of the mother horse and the mother horse should be emphasized. Using this data, it can be seen that the predicted successful bid price of the racehorse that is the target product (hereinafter referred to as the target racehorse) is about 47 million yen, and about 47 million yen can be used as a guideline for determining the bid price. Further, in the prediction data 15b, the winning bid price of the sibling of the target competitive horse is recorded. The actual price and the weighting coefficient have the same meaning as in the prediction data 15a. Using this data, it can be seen that the expected bid price of the target racehorse is about 61 million yen, and about 61 million yen can be used as a guideline for determining the bid price.

  FIG. 4 shows prediction data 15c and 15d used for predicting the proper winning bid price of the painting. These data are investigated and input when the participant b recruits joint investors, but the participants c1 and c2 may input or may be requested by a third party. Moreover, the member can select which of the prediction data 15c and 15d is used.

In the prediction data 15c, the winning bid price and the winning bid year of a picture produced by the same artist as the target picture and awarded within a certain period are recorded. The actual price and the weighting coefficient have the same meaning as the prediction data 15a, but here, an example is shown in which a difference is provided in the weighting coefficient on the assumption that the evaluation of the painter has suddenly increased since 2003. Using this data, it can be seen that the expected price of the target picture is about 11 million yen, and a value of around 11 million yen can be used as a guideline for determining the bid price. Further, the area of the painting is added to the prediction data 15d in addition to the price prediction information 15c. When it can be considered that the painting price is almost proportional to the painting area, the accuracy can be further improved by correcting the painting price by the ratio of the painting area. When the painting area of the subject painting is assumed to be 6000cm ^2, Using this data, the successful bid expected price of the subject painting was found to be about 10.6 million yen, be a measure of the bid price determines the before and after 10.6 million yen it can.

  FIG. 5 shows prediction data 15e used for predicting the expected payout of the target racehorse. This data is also surveyed and input when the participant b recruits joint investors, but the participants c1 and c2 may input or may be requested by a third party. Moreover, the member can use the prediction data 15e selectively or simultaneously with the prediction data 15a and 15b.

  In the prediction data 15e, lifetime winnings of each of the foal and the mother horse and the target competitive horse are recorded. The central activity year is an activity year in which the father and the mother have mainly won prize money, and the actual price and the weight coefficient have the same meaning as in the prediction data 15a. Using this data, it can be seen that the expected lifetime winning prize price of the target competing horse is about 92 million yen. Since the prize money of 30 million yen has already been won, the future prize money, that is, the expected total dividend amount will be about 62 million yen, and around 62 million yen can be used as a guideline for determining the bid price. If the target racehorse is expected to have a certain value such as a seeding price in addition to the dividend, the data may be added to the dividend amount.

  Next, the flow of the joint bidding method of the auction according to the present invention will be described in detail with reference to the flowchart of FIG. In the figure, the thick frame portion has a related drawing, and the figure number is also shown. When the auction for a certain product P is started, the auction site server AS notifies the fact by a homepage or e-mail (step 31). Participant b obtains this information from participant terminal B, and requests management server S to display that it is seeking a joint investor (step 32). At this time, the participant b transmits the auction site information 11, bid information 12, and price prediction information 15 to the management server S together (step 33). Furthermore, if necessary, the participant b transmits his / her initial investment amount from the participant terminal B to the management server S (step 34). Here, it is assumed that the participant b designates 10 million yen as the initial investment amount and transmits the data shown in FIGS.

  The management server S receives this signal and creates input support data 1a based on the received auction site information 11, bid information 12, and price prediction information 15. In addition, information calling for joint investment for the product P is placed in a state where it can be viewed from the participant terminals C1 and C2 together with the input support data 1a (step 35).

  An example of the browsing screen on the participant terminals C1 and C2 at this time is shown in FIG. On the browsing screen, general information 201 generated from the auction site information 11 and the bid information 12 is displayed. In the group investment information 202, since there is no joint investor at this time, only the participant b is displayed with the investment amount of 10 million yen. The intra-group investment information 202 further displays a proper successful bid price generated based on the price prediction information 15 and an expected dividend. Here, the calculation pattern of the appropriate successful bid price is the pattern 1, that is, the calculation pattern using the prediction data 15a (the pattern 2 is the calculation pattern using the prediction data 15b), and the calculation pattern of the expected dividend is the same. The pattern 1, that is, the calculation pattern using the prediction data 15e is applied. The appropriate successful bid price calculation pattern 203 is displayed so that “1” or “2” can be selected, and the participants c1 and c2 can switch the prediction data 15a and 15b to be applied based on their own judgment. Since only the predicted data 15e is recorded in the predicted dividend calculation pattern 204, only “1” is displayed, and switching to other data is not possible. Since the bid status of the other party is unconfirmed at this time, the bid information 205 is blank. A participation registration button 206 is displayed below the browsing screen, and encourages participants c1 and c2 to participate in joint investment.

  If the participants c1 and c2 think that they can jointly invest, the participation registration button 206 is pressed to perform the participation procedure, and the initial investment amount is input together (step 36). When the management server S receives the application for joint investment from the participants c1 and c2, the management server S registers the participants c1 and c2 together with the investment in the bid support information 14, and updates the bid support information 14. At this time, not only the column of the participant and the investment amount, but also the appropriate bid price 146 by member and the expected dividend 147 by member according to the investment amount are automatically updated. In addition, the initial investment amount is summed, and the capital contribution 141 of the entire joint investor is calculated. Further, the management server S receives bid information indicating when and how much has been bid from the auction site server AS (step 37), and generates bid status information 13. The management server S updates the bid support data 1a in this way (step 38).

  In FIG. 8, the example of the browsing screen in participant terminal C1, C2 at this time is shown. Since this information can be viewed at all times from the participant terminals C1 and C2, the participants c1 and c2 have a minimum bid price that is less than that, or the total amount of capital is less than the maximum bid price. Can also add the investment amount sequentially, and the result is immediately reflected in the bid support data 1a. If the maximum bid price is not reached even after the lapse of a predetermined time, the management server S may automatically send a notification to that effect to the member. FIG. 8 shows that participants c1 and c2 have already had three bids, and that the total investment amount is less than the maximum bid amount. It is at the time of exceeding.

  Participant b issues a command to bid for management server S at an appropriate timing (step 39), and management server S executes a bid for auction site server AS (step 40). At this time, a bid may be directly placed on the auction site server AS from the participant terminal B, and the management server S may detect it.

  The auction site server AS accepts bids from the participant b (step 41), and updates bid information every time there is a bid (step 42). The management server S acquires bid information from the auction site server AS at a predetermined timing, and updates the bid support data 1a (step 43).

  This information can be viewed on the participant terminals B, C1, C2, so that if the other person raises the bid price, the participants c1, c2 can add funds (step 44), Participant b may make an additional investment (step 45). The result is immediately reflected in the bid support data 1a (step 46). If the total amount of funds is less than the maximum bid price even after the lapse of a predetermined time, the management server S may automatically send a notification to that effect to the members.

  Participant b issues a command to specify a price higher than the highest bid price and re-bidding to management server S at an appropriate timing (step 47), and management server S sends the auction site server AS. A re-bid is executed (step 48). The auction site server AS accepts a re-bidding from the participant b (step 49). Thereafter, when the highest bid price rises, each step in the range 51 of FIG. 4 is repeatedly executed, and the bidding is completed (step 50). FIG. 9 shows the browsing screen at this time. This figure is the viewing screen for participant c1, and participant c1 has already switched to the appropriate bid price pattern 2 because the highest bid price has already exceeded the price in the appropriate bid price pattern 1, and is still bidding with reference to it After confirming that the price was not unreasonably high, he increased his investment.

  The effects of the present invention are as follows.

  For co-investors, it is possible to share information for determining the appropriate price with the bidder, so it is possible to judge the necessity of participation in the investment and additional investment based on objective data, and make a successful bid at an appropriate price. More opportunities to do it.

  In addition, for joint investment solicitors, recruitment of joint investors and additional investment by joint investors will be carried out smoothly, increasing opportunities to make a successful bid at an appropriate price and reducing the risks borne by them.

  As described above, the auction system according to the present invention is intended for bidding that is profitable by reselling or that can generate new profits after growth, such as a racehorse, and can obtain dividends. In online auctions, increase the chances of bidding in a timely manner and making a successful bid at an appropriate price by connecting the joint venture solicitors and joint investors of the auction via a communication network and sharing support information necessary for bidding. It becomes possible.
