为探索多重条件并发对平台企业商业模式创新的影响,基于机会资源一体观构建商业模式创新路径模型,通过对193个样本进行模糊集定性比较分析发现：平台企业商业模式创新路径形成依赖机会开发和资源联动层面要素的组合;机会开发和资源联动层面不同要素的组合形成两类商业模式创新路径,类型1强调模仿型机会开发与资源联动策略组合,类型2强调创新型机会开发与资源联动策略组合;机会开发适配的资源联动方式存在差异,其中模仿型机会开发与资源共享和资源编排匹配良好,而创新型机会开发与资源编排、资源拓展匹配良好。研究结论揭示了平台企业商业模式创新多条等效路径,丰富了商业模式创新前因研究,也为平台企业商业模式创新实践提供了理论指导。 相似文献

创业者经验对创业机会识别的影响机制研究 《科学学研究》2017,35(3):419-427
基于现有创业经验学习理论,系统分析了创业者经验、创业学习、创业自我效能、创业机会识别四者之间的内在关系,构建了“创业者经验对创业机会识别的影响模型”,深入探讨创业者经验对创业机会识别的作用机制。通过对宁夏地区四个城市的新创企业进行实地调研,实证结果表明创业者经验、创业学习、创业自我效能对创业机会的识别具有显著的正向影响;探索型学习、创业自我效能在创业者经验和创业机会识别之间起着部分中介作用,应用型学习在创业者经验和创业机会识别之间的起着完全中介作用。 相似文献

虽然许多学者都强调创业学习对于创业的重要性,但是现有研究仍停留在概念阶段,对于创业学习作用机理的研究明显不足。在对长春和杭州实地调研的基础上,试图探索不同创业学习方式(经验学习和认知学习)如何通过影响创业能力(机会识别能力和机会利用能力)的构建而对新企业绩效产生作用,从而揭示创业学习与新企业绩效的内在关系。研究表明经验学习和认知学习均对新企业绩效存在积极影响,机会识别和利用能力均对新企业绩效存在积极影响,并且创业能力在创业学习与新企业绩效之间的关系起着中介作用,但是不同创业能力在两者间的中介作用存在差异。 相似文献

基于178家企业的样本数据,研究关系网络影响创业机会识别的内在机制。结构方程建模分析结果表明:关系网络不仅可以直接预测创业机会识别,还可以通过认知和经验学习以及实践学习间接预测创业机会识别。此外认知和经验学习对创业机会识别的预测作用相同,认知学习相比于经验学习对实践学习的预测作用则更强。 相似文献

随着互联网+、全球化等的深化,商业模式设计成为企业形成可持续竞争力的重要来源。本文运用组态思维与模糊集定性比较分析方法(fsQCA),以“华为离职江湖系列”中的25个案例为研究对象,探究组织层面与离职创业员工个体层面的4个前因条件对离职创业企业商业模式设计的共同影响机制。研究发现：实现效率型商业模式设计的组态有4种,而实现新颖型商业模式设计的组态仅存在1种,其中效率型商业模式设计组态可归纳为先前经验和企业家精神缺乏引致型与企业家精神驱动型两类;相较于效率型商业模式设计,新颖型商业模式设计对离职创业者提出了更高的要求;缺乏先前经验且企业家精神相对较弱的离职创业者更倾向于选择效率型商业模式设计;知识惯性在商业模式设计过程中发挥着不容忽视的作用。 相似文献

数字时代促使传统企业的产品服务之争演变为商业模式之争,随着“工业时代”向“数字时代”的转变,数字平台突破规模经济的“管道”,凭借网络效应和生态优势实现了迅速扩张。数字平台商业模式演进成为业界关注的热点。通过以猪八戒网为案例,采用纵向单案例研究方法,融合企业家精神和行动学习的理论视角,以“动因—行为—结果”为逻辑探析数字平台商业模式演进机理。研究发现：在企业发展的三个阶段,企业家精神是数字平台商业模式演进的关键驱动力,企业家精神实现了“个人—组织—社会”层面的不断进阶,并通过“生存—成长—转型”导向的行动学习,驱动商业模式实现“连接型—赋能型—生态型”的成功演进,由此构建出数字平台的企业家精神对商业模式演进机理模型。该模型揭示了数字平台商业模式演进的三个阶段：在生存期,以风险承担为主的个人企业家精神,驱动创始人开展生存式行动学习,识别出服务非标、需求低频的生存瓶颈,通过内外部经验反思,平台连接服务供需双方,开拓业务并迭代交易模式,以此激发平台存量资源实现连接型平台商业模式演进;在成长期,以创新导向为主的组织企业家精神,驱动平台开展成长式行动学习,明确平台业务增长滞缓的成长瓶颈,结合内部数... 相似文献

高管团队失败学习促使企业选择全新的商业模式还是在原有模式上继续改进,是企业界和学术界共同关注的话题。基于经验学习和组织惯性理论,发现高管团队失败学习与新颖型商业模式之间呈倒U型关系,与效率型商业模式之间呈正相关关系。在新创企业中,高管团队失败学习与新颖型商业模式设计之间仍存在倒U型关系,但在在位企业中,两者之间呈U型关系。此外,还发现,与新创企业相比,在位企业中高管团队失败学习与效率型商业模式设计之间的正向关系更强。 相似文献

创业失败修复对科技型企业失败再创业具有重要作用,但在资源有限约束下需要对创业失败的科技型企业进行甄别,才能发挥好资源支持对科技型企业创业失败修复的效用。为了对科技型企业创业失败修复对象进行科学、准确地甄别评估,在系统分析科技型企业创业失败源的基础上,从属性归因和因果归因的双重维度,构建了包括创业资源获取能力,资源、渠道和方式,创业机会识别能力,市场条件,团队关系和团队正式化等6个一级指标的科技型企业创业失败修复对象甄别评估指标体系,并综合运用区间AHP法、熵权法和拉开档次法,设计了一种主观赋权和客观赋权相结合的组合赋权方式,建立了科技型企业创业失败修复对象甄别评估模型。同时,应用模型对10家创业失败的科技型企业实践案例对象进行了甄别评估。结果表明,根据评估结果在不同属性-因果维度的得分,将科技型创业失败企业划分为能力不足型、缺乏远见型、关系矛盾型、资源稀缺型、市场不佳型和团队背叛型6个类型。研究结论为科技型企业创业失败修复的对象甄别提供一种可供参考和借鉴的思路。 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

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

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

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
