基于模糊聚类和灰色关联度的项目管理评标方法的研究

通过客观公正地评标、选择最优的项目管理者是成功地实施项目代建的必要条件。首先通过分析项目管理招标评标的特点,建立相应的项目管理评标体系;然后,将模糊聚类理论与灰色关联分析相结合,对项目管理投标人进行综合评价。与以往的评标方法相比,招标人在获得最优投标人信息的同时,还能够对投标人按照综合能力进行分类对比,从而为招标人提供更加全面翔实的评标信息。

基于GPO的医疗供应链体系的优化研究

在医疗领域,集团采购组织(Group Purchasing Organization,GPO)以较低的采购成本和优质的服务逐渐受到人们的关注,借鉴国外基于GPO的医药供应体系的经验来优化我国的医药采购模式具有重要的现实意义和价值。这篇文章基于对GPO理论的综述和现行医疗供应链体系的分析,认为可以借鉴国外的GPO采购模式优化我国的医药供应链体系,通过构建GPO采购模型,得出GPO能够达成供求双方利润分配的平衡和医疗供应链的优化的结论。     

School quality as a catalyst for bidding wars and new housing development

We provide new evidence of the demand for better schools as manifested in bidding wars and changes to the built environment. Using repeat sales before and after a redistricting, we exploit shocks to school quality arising from the continuous, unexpected redistricting of school attendance boundaries in Atlanta. We find that houses redistricted to higher (lower) quality schools are more (less) likely to be involved in a market-driven bidding war. Similarly, undeveloped, redistricted parcels that receive a positive (negative) school quality shock are more (less) likely to be developed. School quality shocks also have a causal effect on house prices and time-on-market.     

评标规则如何影响电力物资招投标管理

在实际的电力物资招投标管理过程中，由于各个参与者间存在着巨大的经济利益往来，以及以往常用的电力物资招投标中评标策略的落后，导致电力物资招投标方面一直存在着诸多问题。文章以拍卖机制在招投标中评标环节的运用和成效入手，全面探讨了各种拍卖机制在招投标评标环节中的运用，以第二价格拍卖理论入手，运用博弈论验证实施成效，以改善现行电力物资招投标模式下存在的不良问题。     

Optimal seller strategy in overlapping auctions

Little research has been conducted on a common phenomenon in today's online environment: the concurrent selling of identical products in online auctions. To fill this gap, the current research proposes a game-theoretical model to analyze the seller's optimal strategy for selling two identical items in overlapping auctions. The overlap is modeled endogenously (as the seller's decision), trading off multiple influences including the positive effect on the overlap from bidders' forward-looking behavior and the seller's time discounting, versus the negative impact from bidders' learning and varied demand (i.e., bidder entry). The combined impact of these factors governs the conditions for which a simultaneous, sequential, or partially overlapping strategy is optimal. When the effect of bidders' forward-looking behavior and/or the seller's time discounting dominates, running simultaneous auctions is optimal; when bidders' learning (and bidder entry) dominates, running sequential auctions is optimal. Partially overlapping auctions are optimal when neither effect dominates and the opposing effects are offsetting.

Friends can help: The effects of relationship in the Chinese book-building process

Using detailed bidding information in Chinese IPO book-building process, we find that institutional investors who have a close relationship with the underwriter are more likely to participate in bidding and their bidding prices are higher, compared to other institutional investors. We also find that related institutional investors bid higher when the underwriter is more likely to need or receive their support. Further analysis suggests that related institutional investors gain some benefits for their support to the underwriter, including receiving more shares in profitable IPOs, better timing their exit from the IPO in the open market, and receiving more optimistic earnings forecasts or stock recommendations from analysts of the underwriter. Regarding the economic consequence, we show that the underwriter is more likely to revise the offer price upward if related institutions bid higher. The evidence overall indicates the existence of relationship-driven bidding in the Chinese book-building process.
