在卖家分散化决策和平台面临弹性需求的基础上,分析了固定收费、交易费、两部收费和利润分成制四种价格模式在双边市场中的应用策略,基于平台所获利润对以上四种收费模式进行了比较.研究发现:尽管交易费或两部收费更有利于平台从卖家身上获取更高比例的剩余,但由于扭曲了卖家的努力水平,因此并不一定能够使平台获得更高的利润;利润分成制和固定费都能够激励卖家达到最优的努力水平,而利润分成制获取卖家剩余的能力更强,因此一定在利润上优于固定费;利润分成制在卖家激励方面优于交易费和两部收费,在剩余索取方面是否优于交易费或两部收费取决于卖家的成本,给定卖家类型和外部性强度,当成本在卖家间的增幅较小时,利润分成制带来的利润最优. 相似文献

在当今数字经济和VUCA时代，如何提高创新柔性以响应动态环境是摆在所有制造企业面前的难题，对中小制造企业而言，由于自身资源相对短缺和资源管理能力不足，提升创新柔性的机制具有特殊性。本文基于资源编排理论的过程视角，结合中小制造企业固有特性，引入平台生态嵌入作为构建资源组合的新形式、数据赋能作为实现资源连接和供需精准匹配的前提和基础、价值共创活动作为推动资源有效利用的新途径，建立了三者与创新柔性间的理论模型。基于106家嵌入工业互联网平台生态的中小制造企业样本，通过PLS结构方程和层次回归方法实证检验结果表明：平台生态嵌入对创新柔性具有倒U型影响，并且受到数据赋能的正向调节；价值共创活动在平台生态嵌入与创新柔性间存在部分中介作用；数据赋能对创新柔性具有正向作用，并调节了价值共创活动在平台生态嵌入与创新柔性之间的中介作用。本文在理论上揭开了中小制造企业创新柔性的提升机制，对资源编排理论做出有益补充，同时对中小制造企业如何有效利用工业互联网平台等资源提升创新柔性具有一定指导意义。 相似文献

围绕“如何推动网络平台上自发有序的大众知识技能共享活动”这一核心问题，用知识共享意愿与共享程度测量知识技能型共享经济平台的活跃度，基于生态系统观，从平台内部因素、用户及交易内容、社会外部环境3个维度，分析知识技能型共享经济平台活跃度的影响因素及其作用机理。结果表明，现阶段平台内部因素（界面友好性、服务完备性、活动多样性、安全规范性）、用户及交易内容（提供者数量、需求者数量、产品服务价格，产品服务质量）对平台用户的知识技能共享意愿与共享程度具有显著的正向影响，而社会外部环境（相关领域协同、政府政策环境、社会认同感）的影响并不显著。最后，根据实证研究结果提出相关建议，以期为加速知识技能型共享经济网络平台的发展、调动广泛的社会智慧促进社会全面创新提供参考。 相似文献

在企业、产业组织泛平台化发展的趋势下,平台化组织的创新优势体现在哪些方面,其作用机理又是需要深入研究。本文以员工的创新激情为着眼点,以创新自我效能感为中介变量剖析了平台化企业的人岗匹配和资源赋能所具有的创新优势。以77家企业数据为样本,通过建立跨层次的结构方程模型,得到如下结果：人岗匹配和资源赋能对员工创新激情具有跨层次的正向影响,其中创新自我效能感部分中介了人岗匹配对创新激情的影响,完全中介了资源赋能对创新激情的影响;资源赋能正向调节了人岗匹配对创新激情的直接正向影响;平台化企业的人岗匹配和资源赋能的平均水平要高于非平台企业,平台化企业员工创新激情的平均水平也要高于非平台化企业。该研究有助于解析平台化组织的创新优势,有助于为企业的平台化组织创新实践提供理论支撑。 相似文献

文章讨论了基于人力资本的剃余索取权和剩余控制权的企业所有权的重新安排，认为企业的所有权实质是人力资本和非人力资本(物质资本)对企业剩余权分割，其合理与否直接影响企业的绩效；也探讨了影响剩余索取权的主要因素，以及剃余行为权的行使对企业绩效的影响，区分了人力资本的工资收益与剩余索取收益的根源，井据此阐释了国有企业改革中的问题，试图指出国有企业进一步改革的方向。 相似文献

Aresearch group led by Prof. ZHAI Qiwei from the Institute for Nutritional Sciences under the CAS Shanghai Institutes for Biological Sciences has discovered that even relatively low doses of resveratrol--a chemical found in the skins of red grapes and in red wine--can improve the sensitivity of mice to the hormone insulin, according to a report in the October,2007 issue of Cell Metabolism. As insulin resistance is often characterized as the most critical factor contributing to the development of Type 2 diabetes, the findings“provide a potential new therapeutic approach for preventing or treating” both conditions, the researchers said. 相似文献

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors. 相似文献

With great care, Dr. ZHOU Zhonghe takes out a package wrapped by cotton tissue from a drawer and says: "This is the gem of our collections: the fossil of a bird that lived 125 million years ago!" Then, pointing at a tiny mound, he explains: "Look, this is the claw and that is the head. It was in the egg shell and ready to hatch ... The species fell into a family of waterside inhabitants." 相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction. 相似文献

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies. 相似文献

This essay focuses on universal service and the Internet as means to support social and political participation. The emphasis on access to telecommunications systems in conventional approaches to universal service is contrasted with access to content. A model of the information environment is described that accounts for the roles of content and conduit, both of which are necessary conditions to achieve true access. A method is outlined for employing information indicators to observe or measure the information environment. 相似文献

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means. 相似文献
