现在,企业都已十分重视技术进步,并在科技兴企中做了大量工作,也取得显著成效。然而,也有一些企业,技术进步喊了多年,或者也作了艰苦努力,但并没有实现科技兴企的初衷,企业的技术提高不快,在以科技为核心的国内外市场竞争中失利。其原因是多方面的,但由于认识上存有不少误区,导致技术进步指导思想的偏颇。因此,在当前必须认清以下6个不等式,才能走出干扰技术进步健康发展的误区。一、第一生产力≠现实生产力企业对于科学技术是第一生产 相似文献

In an increasingly globalized and hyper connected business environment, using knowledge strategically is often critical for competitive performance. This article is motivated to illuminate the notion of strategic knowledge management (SKM) in organizations. In this regard, executives need to develop an informed understanding of what types of organizational knowledge (and how much) can be ‘structured’ and/or allowed to ‘proliferate’ in order to sustain both work productivity and innovation capacity toward a harmonious conceptualization of strategic knowledge in their organizations. This conceptual paper is based on analysing certain exemplars of why organizations need to put greater emphasis on the equivalence between codification and personalization in the context of strategic knowledge management. Our explanations on managing strategic knowledge through different examples provide insights and pitfalls that organizations must be aware of and are as follows. Firstly, we argue that an exclusive emphasis on codification or personalization runs the risk of ‘knowledge structuration’ or ‘knowledge proliferation’ respectively in an organization’s strategic knowledge management. Secondly, executives should continuously realize the need to emphasize on equivalence (or congruence) between codification and personalization aspects of SKM in order to keep enduring work productivity and innovation capacity in organizations. Thirdly, we argue that SKM initiatives that prodigiously focus on either codification or personalization can lead to pitfalls despite plenty of managerial interventions. We further believe that our proposed ideas will be worthwhile considerations for executives/leaders responsible for strategy, IT and innovation divisions of the organization to determine whether its organization’s knowledge engine is running smoothly, and if not, where to direct their energy to yield long term and robust outcomes. 相似文献

In a high-technology field such as the software business, there are many companies striving for growth. For small software firms organic growth is a natural way to grow and often the chosen route. Effective knowledge sharing is crucial for an organically growing software company to extract maximum benefit from its existing resources. However, it can be argued that there exist many barriers to effective knowledge sharing in an organic growth context. For companies that have an intention to grow it is important to identify these possible pitfalls lining the growth path. Using an empirical case study, this paper aims to increase the understanding of the biggest potential knowledge sharing barriers that an organically growing software company may face. Management able to recognize such barriers to knowledge sharing could support growth by acting to prevent the barriers from arising and eliminating those already in place. 相似文献

The purpose of this paper is to understand the key issues faced by supply chain (SC), current strategies and trends of this field, understand IT technical issues and implication for business performance and how IT can foster IM and help sort out the SC problems. Studies from different and recognised authors are reviewed, compiled and analysed in two aspects. First, a detailed picture of SC trends, issues and strategies is depicted. After, main concerns about IT, such as its goals, importance, pitfalls, and features are presented. Moreover, current applications of IT in SC and critical problems and competitive advantages in the IT implementation in the supply chain management's competitive priorities are detailed. SC's new configuration and reality have increased the level of uncertainties and risks present in supply chain activities. Some strategies to mitigate these problems have undermined the SC efficiency. Therefore, a new strategy that uses IT to make SC more robust and resilient should be developed. As a holistic problem, a modelling approach (SDDES) should be used as a tool to support this study. 相似文献

During the coronavirus pandemic, policy makers need to interpret available public health data to make decisions affecting public health. However, the United States’ coronavirus response faced data gaps, inadequate and inconsistent definitions of data across different governmental jurisdictions, ambiguous timing in reporting, problems in accessing data, and changing interpretations from scientific institutions. These present numerous problems for the decision makers relying on this information. This paper documents some of the data pitfalls in coronavirus public health data reporting, as identified by the authors in the course of supporting data management for New England’s coronavirus response. We provide recommendations for individuals to collect data more effectively during emergency situations such as a COVID-19 surge, as well as recommendations for institutions to provide more meaningful data for various users to access. Through this, we hope to motivate action to avoid data pitfalls during public health responses in the future. 相似文献

本文分析了高管团队异质性、网络能力与商业模式调适之间的关系,进而探讨了高管团队异质性通过网络能力中介作用影响商业模式调适的机制。为此,本文提出了相关假设并通过层次回归分析对来自181家企业的问卷调查数据进行实证分析检验了这些假设。研究发现：高管团队异质性对商业模式调适具有显著的正向影响;中心能力与效率能力两类网络能力均对商业模式调适具有显著的正向影响;高管团队异质性能够分别通过中心能力与效率能力的中介作用影响商业模式调适。本文有助于丰富和发展商业模式调适、商业模式动态性以及高管团队与商业模式关系理论,也有助于企业实现商业模式对环境变化的适应性改变。 相似文献

在国内外文献研究基础上,引入产业间技术相近度的概念,基于广义C-D生产函数构建了一个测度政府科技资助溢出效应的计量模型,并采用来自《中国科技统计年鉴》（1997—2006）大中型工业企业的面板数据,对政府科技资助、企业自筹R&D等溢出效应进行了实证分析。结果表明：（1）政府科技资助存在溢出效应,其他产业中企业自筹研发资金也存在溢出效应,而且,政府科技资助的溢出效应明显高于其他产业中企业自筹研发资金的溢出效应;（2）企业研发强度影响政府科技资助的溢出效应;（3）科技资助强度影响政府科技资助溢出效应。对于资助强度大于3%的产业,政府科技资助存在明显的溢出效应,政府科技资助对中等资助产业的溢出效应明显高于高资助产业。研究对我国政府制定创新资助政策有着一定的参考价值。 相似文献

尽管商业模式逐步成为企业战略中新的重要分析单元,但商业模式与企业绩效之间的关系仍未揭示清楚,研究成果较少且主要集中讨论商业模式的整体类型特征对企业绩效的影响。本文深入解剖商业模式的结构,将商业模式划分为顾客价值主张、业务活动系统和盈利方式三个构成,并开发出相应的量表,以281家2009-2011年间实现IPO的中国创业板上市公司为样本,运用SPSS软件对顾客价值主张、业务活动系统、盈利方式及它们之间的相互耦合对企业赢利性、增长性、效率性和市场价值四类绩效的影响进行层次回归分析,更全面地解释商业模式对企业绩效造成影响的复杂机理。分析结果表明,商业模式各构成之间的耦合相较于各构成本身的质地而言对企业绩效的影响更为显著。而在商业模式各构成中,顾客价值主张对企业绩效的影响最为显著。另外,商业模式对企业绩效具有不对称性的影响,对盈利性指标和成长性指标的影响最为显著。本文对中国创业企业开展商业模式设计和创新来提升企业绩效和价值具有一定的参考意义,也拓展了商业模式实证研究的分析框架。 相似文献
