【摘要】：近年來網(wǎng)絡拍賣以驚人的速度發(fā)展,互聯(lián)網(wǎng)的應用能夠有效降低拍賣人和競標者的搜索成本,是推動網(wǎng)上拍賣快速發(fā)展的主要因數(shù)。網(wǎng)絡拍賣有獨特的優(yōu)勢：網(wǎng)上拍賣擴大了被拍賣物品的市場,在互聯(lián)網(wǎng)上,賣主可以很容易地在很短的時間內(nèi)找到人數(shù)相對較多的競標者,并且競標者不局限在當?shù)�。此�?通過搜索引擎,競標者可以更方便地找到他所要的物品。金融活動產(chǎn)生于企業(yè)規(guī)模擴張沖動和社會資金投資沖動之間的相互需求。一方面,現(xiàn)代工商業(yè)及金融業(yè)發(fā)展往往需要通過合法的金融手段募集閑置社會資金,通過資源互補實現(xiàn)企業(yè)的發(fā)展進步；另一方面,社會上存在大量的閑置資金,具有天生的投資增值需求。我們嘗試一種新的募集資金的方式,即電子商務拍賣融資。通過網(wǎng)絡平臺可以跨越地域局限,虛擬集成項目和投資者,降低集體競價的成本。網(wǎng)上拍賣可以由投資者選擇出價范圍,更加靈活；各方在競價過程中可自由交流；憑借網(wǎng)站自建的信用評價系統(tǒng),借助所有用戶的監(jiān)督力量來營造一個相對安全的交易環(huán)境,買賣雙方都能找到可信賴的交易伙伴。本文綜合考慮投資價格,需求利率,周期,信譽等方面,設計一種帶有縱向價格歧視的多贏家拍賣模式。每個投標包含投資金額和利率兩種投標信息,投資者可以自主選擇出價區(qū)間,不同的出價區(qū)間對應不同的需求利率,拍賣以資金募集者最佳收益為目的選擇勝標,每個新投標都可能對勝標結(jié)果造成影響。用分枝定界法求解標模型,設計算例進行仿真,并引入信譽機制改進模型。
[Abstract]:In recent years, with the rapid development of online auction, the application of the Internet can effectively reduce the search cost of auctioneers and bidders. Online auction has a unique advantage: online auction has expanded the market for items to be auctioned, and on the Internet, Vendors can easily find a relatively large number of bidders in a short time, and bidders are not limited to local ones. In addition, through search engines, It is easier for a bidder to find what he wants. Financial activity arises from the mutual need between the impulse to expand the size of the enterprise and the impulse to invest in social capital. On the one hand, The development of modern industry, commerce and finance often needs to raise idle social funds through legal financial means, and realize the development and progress of enterprises through complementary resources. On the other hand, there are a large number of idle funds in society. There is a natural need for added value. We try a new way to raise money, that is, electronic commerce auction financing. Through the network platform, we can transcend geographical limitations, virtual integration projects and investors, Reduce the cost of collective bidding. Online auctions allow investors to choose the range of bids, more flexible; all parties can freely communicate in the bidding process; with the website's own credit evaluation system, With the help of the supervision of all users to create a relatively safe trading environment, both buyers and sellers can find reliable trading partners. A multi-winner auction model with vertical price discrimination is designed. Each bid includes two kinds of bidding information: investment amount and interest rate. Investors can choose the bid range on their own, and different bid ranges correspond to different demand interest rates. Each new bid may have an impact on the result of the winning bid. The branch and bound method is used to solve the bidding model, and an example is designed for simulation, and an improved reputation mechanism model is introduced.
