A vast literature on technology transitions within industries suggests that early phases of new technologies are marked by periods of intense experimentation, but we know little about the conditions under which these periods emerge. We apply inductive, grounded theory-building techniques to examine what prompts firms to experiment across one emerging technology platform—plug-in electric vehicles (PEVs)—in China. Triangulating annual vehicle make and model sales data from 2003 to 2016 (plus monthly data from 2010 to 2016); 112 English and Mandarin archival documents from industry, academic, and news outlets; and 51 semi-structured interviews with industry, government, and academic stakeholders, we develop four in-depth case studies. We find that in contrast to the innovation trajectories of multinational and Chinese arms of joint venture (JV) firms, independent domestic Chinese firms (those with no history of international JV partnerships) are undertaking significant experimentation across multiple levels—infrastructure, core system, subsystem, and component—of the emerging PEV technology platform. We propose the concept of “institutional complementarities” to describe how interactions among institutions—here the national JV regulation and local market support and subsidies—may have turned regional markets into protected laboratories, extending the incubation periods for independent domestic firm experimentation. While this diverse experimentation may be an important antecedent of technology transition, consolidation induced by national policy standardization or competitive pressure may be required for PEV innovations to scale beyond their early, protected regional markets. 相似文献

An account of the process of constant experimentation that drives our industry-leading newsletters and web site; the lessons
behind our entrepreneurial experiences that should be meaningful to many within book publishing; and suggestions for how publishers
of all sizes can employ a similar mindset in getting closer to readers and leveraging their natural assets for success in
today’s rapidly changing marketplace.
This paper was presented during the “Making Information Pay 2008” conference organized by the Book Industry Study Group, as
a different kind of text as far as I am concerned than an essay. What I actually said the day of the presentation was undoubtedly
somewhat different than what is written here. 相似文献

徐阶成功扳倒严嵩后,推行“三语政纲”,以期扭转嘉靖后期的怠政、朝政混乱、言路大坏等政治弊病。但由于其本身存在的局限性,以及措施的失当等原因,收效甚微,甚至某些举措非但于事无补,反而使问题愈加严重。因此,“三语政纲”并没能真正挽救嘉靖末年的社会政治危机。 相似文献

基于科学数据管理生命周期理论与科学数据管理能力成熟度模型,从建设基础(政策、经费、技术、团队)及管理过程(数据管理计划、采集标准与流程、描述与元数据、存储与保存、共享与保护、应用与服务)两个维度对比国内外11个健康医学科学数据管理平台的建设实践。调查发现,国内健康医学科学数据管理政策不够完善,缺少保障健康医学数据安全及个人隐私的法规;平台提供的服务强调健康医学科学数据存储,而对数据管理与共享的支持不足。基于国外成熟经验,本文从完善激励机制与数据政策、扩大经费来源、增强技术创新、保护数据安全和促进数据共享、深化服务内容5个方面对国内健康医学科学数据管理平台提出建议。 相似文献

Open data is considered an important resource to stimulate innovation and create economic and social value. Open data researchers have examined the importance of data publication by public bodies, but in contrast, much less attention has focused on how open data is exploited. In this paper, we aim to provide insight into the actions of platforms to assist open data exploitation by transformational entrepreneurs, which systemically facilitate transformation in socio-economic development. Our findings investigate two types of mechanism, reflecting the openness of the data movement and the competitive commercial need for closure. First, inclusion mechanisms are social mechanisms of the open data ecosystem which seek to attract a broad range of potential collaborators through supporting entrepreneurs to innovate with open data. Second, exclusion mechanisms are deployed to filter collaborators, to identify those who are seen by platforms to be more likely to successfully exploit their data, or develop revenue sharing relationships. We reveal how these mechanisms are used at different stages of the innovation process, to initially attract a wide pool of collaborators, before seeking to reduce them to better target limited resources. Despite ‘openness’ being a key requirement of open data publication, for successful transformational entrepreneur exploitation, it requires dimensions of closure. 相似文献

开放获取期刊平台发展现状评析 总被引：1，自引：0，他引：1
开放获取期刊(OAJ)平台是OA关键基础设施,对促进OAJ的发展、传播和利用均有重大意义。它是国家/机构科技期刊的宣传展示平台,是图书馆科技文献资源和服务体系的重要组成部分,是商业信息服务机构的推广平台。通过对8个OAJ平台资源建设和用户服务现状考察发现,OAJ平台在资源纳入和剔除标准、评价体系,高级检索功能,交互式服务、相关知识链接、互操作性还存在不足;与检索性平台相比,OAJ全文平台在增值服务上具有明显的比较优势。未来OAJ平台应不断完善平台资源组织、资源评价的制度和方法,注意规避知识产权风险。 相似文献

This article summarizes the methodology and findings of the Online Catalogue and Repository Interoperability Study (OCRIS), a project recently carried out by the Centre for Digital Library Research at the University of Strathclyde, funded by the Joint Information Systems Committee (JISC). In the context of the Online Public Access Catalogs (OPAC) and the recent development of the Institutional Repository (IR) within Higher Education Institutions in the United Kingdom, it considers issues of metadata quality, name authority control, and standardized subject headings, as well as departmental and institutional workflows. It also considers duplication and scope overlap within institutions with more than one IR. 相似文献
