Win-Win situations are used and also created by companies which cooperate with each other, complement each other on a synergy basis and work together fairly and competently. Today, business partnering has therefore become a key qualification for companies. This should not depend alone on the commitment of individual persons.This article describes how Siemens has organized its company, services and products using partnering solutions and how it has installed this concept as an intrinsically dynamic process. Thanks to institutionalized partnering, B2B interfaces have been established to form a rational alliance, offering benefits to all involved, and can be used regardless of the size of the company. These offerings generate Win-Win situations themselves—and provide individual employees in large companies with a structural framework for a personal partnering initiative.  相似文献

New product development (NPD) has long been recognised as one of the corporate core functions. However, measuring new product success has remained elusive. This paper attempts to examine several conceptual issues underlining the measurement of new product success and the measurement practice adopted in Australian small and medium enterprises (SMEs). The sample included 276 SMEs from two most innovative industries: chemical and machinery industries. Results have indicated that four factors underline the commonly used success measurement: financial performance, objective market acceptance, subjective market acceptance, and product-level measures. These four factors are related to each other and can be used to well predict the overall measurement. The most frequently used specific measures in Australian SMEs are customer acceptance, customer satisfaction, product performance, and quality.  相似文献

The adoption of sophisticated supply chain innovations by trading partners in global channels of distribution is often limited by the institutional context of the international transaction. In particular, the regulatory, normative, and cultural-cognitive elements of institutional environments around the world can enhance or inhibit the ability of trading partners to craft the contractual, ownership, and social elements of institutional arrangements required by an innovation. Because supply chain innovations often require costly, new investments and activity sets, firms may be reluctant to participate in an innovation unless a new institutional arrangement can be crafted to provide adequate safeguards and guarantees. A conceptual model is developed to explain the role of institutions in the successful deployment of supply chain innovations in global marketing channels.  相似文献

中国政府对高新技术企业投入了大量补贴以激励它们创新,但是对补贴效果的研究并未达成一致结论。基于中关村3万多个高新技术企业2001-2012年的观察值,本文同时采用PSM与DID法对政府补贴的效果进行了研究,结果发现:第一,整体而言,政府补贴显著提高了创新经费支出、新产品销售收入和专利申请数量;第二,进一步将创新细分为自主创新和购买引进新技术之后发现,政府补贴存在“挤出效应”:被补贴企业的自主创新明显下降,而购买引进新技术显著增加;第三,政府补贴对企业的短期创新激励有显著的促进作用,但是对长期创新激励的促进作用不显著。本文对高新技术企业的补贴效果提供了实证绩效评估,所得出的结论有助于政府优化和调整激励创新政策。  相似文献

ABSTRACT

This study, utilizes an innovative methodological approach, fuzzy-set Qualitative Comparative Analysis (fsQCA), investigating the drivers of heterogeneous geographies characterizing English Local Economic Partnerships (LEPs). The fsQCA technique offers a novel configurational alternative to regression-based approaches investigating the effects of clustering in conjunction with firm-level innovation, university third-sector activity (TSA) and entrepreneurship, on LEPs innovation performance. The findings, offer contributions to the theories of industrial clusters and innovation, regional innovation systems, knowledge spillovers and entrepreneurial university innovation within LEPs. First, supporting fsQCAs, no individual variable generates either a positive/negative innovation outcome. Second, while all positive innovation recipes include presence of the cluster variable, for negative innovation recipes, only one does not identify absence of clustering as relevant. Given that the cluster variable does not appear in any recipes without at least one of the other variables suggests activity concentration does not exist in isolation to generate innovation outcomes without other localized conditions existing, e.g. firm-level innovation. Third, there is evidence for the non-cluster-based aspects of knowledge spillover theory of entrepreneurship with respect to university activity and the entrepreneurial university concept. Instead, roles of entrepreneurship and university TSA, while important, appear to be more peripheral and geographically context specific.  相似文献

在我国当前内部控制的教学模式相对落后、教学改革几乎空白的背景下,本文以四川师范大学商学院财务管理专业为依托,针对《内部控制学》课程的教学内容制定了“实践模拟教学体系”,为保证教学目标的实现构建了“组合式教学法”.灵活多样的教学方法相互融合且交替使用于不同的教学内容中,由此设计出一套完整严密的教学改革总体方案.  相似文献
