将数字技术能力细分为数字技术创新和数字技术获取两类能力、商业模式创新分为技术导向型和消费导向型两类创新,以商业模式创新作为中介变量构建数字技术能力与企业绩效之间关系理论模型,并提出三者之间关系的研究假设,基于沪深股市32家数字技术上市公司的公开数据,采用多元回归分析方法验证研究假设.结果 表明:(1)企业的数字技术能力具有原动力作用,均能够促进企业开展商业模式创新和提升绩效,但必须借助商业模式创新才能达到实现企业可持续盈利目的 .其中两类能力均对企业绩效有显著正向影响,但对两类商业模式创新影响不同:数字技术创新能力对技术导向型商业模式创新有显著正向影响,对消费导向型商业模式创新影响不显著;数字技术获取能力对消费导向型商业模式创新有显著正向影响,对技术导向型商业模式创新影响不显著.(2)商业模式创新能够促进企业绩效提升但中介作用有限,其中技术导向型商业模式创新对企业绩效起完全中介作用,技术创新是数字技术企业最好的商业模式. 相似文献

商业模式创新是决定新创企业生存和成长的关键性战略问题。尽管商业模式创新对于新创企业至关重要,但是学者对于新创企业的商业模式创新研究尚未引起重视。基于此,本文首先提出了新创企业商业模式创新的内涵,比较分析了新创企业商业模式创新的特征;然后对近10年来的文献进行总结,归纳出新创企业商业模式创新的驱动因素;以此为基础,整合理性定位、进化学习和认知三个战略视角,提出新创企业商业模式创新的一个整合性分析框架,为新创企业开展商业模式创新提供一定的借鉴和参考。 相似文献

越来越多的在位企业基于自身资源和能力以及外部机会进行商业模式创新,不断衍生出新的商业模式,实现颠覆性成长。基于此,本文在商业模式创新基础上提出商业模式衍生式创新的概念,以市场和技术作为商业模式创新的驱动因素,结合探索和利用的创新方式识别出4种商业模式衍生类型并探寻了具体的衍生机制。研究表明,不同的衍生类型在价值主张、价值创造与价值获取方面表现有所不同,衍生后的商业模式之间在空间、时序以及创新程度方面表现出差异化的关系属性。对商业模式衍生式创新具体衍生机制、类型的识别以及不同关系的探讨,呼应了商业模式创新以及商业模式组合等相关理论,将为企业进行商业模式创新的实践以及对不同商业模式的投资和治理提供有价值的洞见和指引。 相似文献

虽然目前化学药品面临研发创新困难、价格管制严格的挑战,但从市场和医疗角度分析,其在中短期内仍将是制药产业的主流。我国化学药品的发展面临着重复仿制、产能过剩的局面,为了积累研发能力和经济实力,制药企业需要从系统的商业模式角度来思考和设计化学药品的研发和市场工作。采用商业模式的分析框架研究目前中国市场上运作较为成功的四种化学药产品,通过剖析其商业模式要素,发现其商业模式可分为三大类型：价格导向型、研发导向型、全面发展型。通过对三种类型商业模式的综合比较,为面对技术能力和产业追赶的企业提供商业模式视角的参考和建议。 相似文献

本文探究了数字经济时代企业商业模式创新能否以及如何影响盈余管理。研究发现,商业模式创新显著提高了企业盈余管理程度,这主要与商业模式创新提高了企业的融资需求有关。同时,不同商业模式创新类型对不同盈余管理的影响存在差异：定位创新、盈利模式创新和现金流结构创新会显著影响应计盈余管理;而业务系统创新则会显著影响真实盈余管理。从治理视角进一步分析发现,相较而言,商业模式创新对盈余管理的影响在分析师跟踪少和媒体关注度低的样本中更为显著。上述研究在一定程度上揭示了商业模式创新对盈余管理影响的内在机制,从信息披露治理角度为推动商业模式创新实践提供了重要的经验证据。 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

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

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP. 相似文献

<正>In Xishuangbanna,one of China’s most biodiverse regions,landscape has changed dramatically during the past three decades due to the conversion of tropical rainforest to rubber plantations.In steep areas,terraces are often constructed before planting rubber trees,which causes two important changes in the soil:the destabilization of soil in the bench terraces and the increased vulnerability of unvegetated riser faces to erosion.Few studies have documented the nature and intensity of erosion on bench terraces.Prof.LIU Wenjie and his colleagues from the Xishuangbanna Tropical Botanical Garden(XTBG)conducted a study in Menglun County(21°5′39″N,101°15′55″E),Xishuangbanna to evaluate the influence 相似文献
