How do firms balance explorative and exploitative innovation for superior firm performance? While most prior studies have approached this issue by focusing on technology‐related innovation, the role of balancing exploration and exploitation in other important organizational domains, i.e., marketing, and the interaction effect of ambidexterity across different domains have been overlooked. This study contributes to this line of research by investigating how firms simultaneously balance exploration and exploitation across two critical domains, namely technology innovation and market innovation. The study distinguishes four types of configurations: market leveraging (technology exploration and market exploitation), technology leveraging (technology exploitation and market exploration), pure exploitation (technology exploitation and market exploitation), and pure exploration (technology exploration and market exploration). From an organizational ambidexterity perspective, the current work investigates whether and how these different combinations exert distinctive effects on firm performance. Specifically, the article posits that (a) technology exploration and market exploitation complement each other, and (b) technology exploitation and market exploration also complement each other, such that both market leveraging and technology leveraging strategies have positive effects on firm performance. The article also maintains that such positive relationships are fully mediated by differentiation and low cost advantages. Conversely, it is argued that (c) technology exploration and market exploration conflict with each other, and (d) so do technology exploitation and market exploitation, such that both pure exploration and pure exploitation have negative effects on firm performance. Hypotheses were tested using survey data collected from 292 manufacturing and service firms in China. The results supported most of the hypotheses, except that pure exploration demonstrated no significant relationship with firm performance. 相似文献

There is an ongoing discussion in the market which Next Generation Access (NGA) architecture best suits future needs and which investment and cost differences exist. The discussion can be subsumed as P2P vs. GPON, which is somewhat misleading as this article reveals. The discussion is driven by the fact that the high capital cost and the long asset life time of fibre mean that the technology choices made today will dominate the opportunities for telecommunication business of all market players, incumbents, competitors, content providers and business and residential users for many years in the future.The paper analyzes the cost and other differences between Fibre-to-the-Home (FTTH) access network architectures and their related different wholesale approaches by using the well-known and understood steady state approach applied in other NGA analyses in the past. In addition to the steady state analysis a dynamic cost evaluation is included taking into account the different investment behaviour of the FTTH architectures over time. The results describe investment and cost differences between architectures, incumbents and wholesale based competitive operators. The analysis has been performed for different geotypes (clusters) of decreasing population density in a representative European settlement structure. 相似文献

The U.S. beef and pork industries have achieved dramatic productivity growth in recent decades; however, the supply chain and market structure of each industry has evolved in different ways. Technological advances have been a key reason for productivity growth, with pharmaceutical innovations playing a major role. This article canvasses the similarities and differences in how beef and pork flow through their respective supply chains and documents the changes, causes, and benefits of the increased efficiency in each industry. Past research is summarized in a broad view of the livestock industry and policy and trade issues are discussed. Such a perspective allows for the consideration of what the future might hold for each industry, and how technological innovation influences product quality, trade, and market structure. 相似文献

Within this paper, a conceptualised triadic schema is hypothesised for locating emotion within a creative, learning and product
orientated Design and Technology experience. The research is based upon an extensive literature review that has been synthesised
and juxtaposed with the broad aspirational aims of the subject. The schema, based upon abductive reasoning and grounded theory,
ultimately conceptualises the overarching theme of emotion within a creative, learning and product orientated Design and Technology
experience within the Primary and Secondary stages of England’s education system. The triadic schema offers an additional
opportunity in meta-theorising how the broad aspirational aims of the subject, as outlined in the English national curriculum
statement of importance for Design and Technology, can be achieved through recognising the powerful overarching concept of
emotion within three emerging domains: Person, Process and Product. The central tenet of this paper is the recognition of
emotion within a triadic schema for meta-theorising the place of emotion within a creative, learning and product orientated
Design and Technology experience.

A strategic skill based model of supplier integration and its effect on supply management performance 总被引:1,自引:0,他引:1
Supplier integration is a tool to help organizations gain competitive advantage. Strategic supply management skills and the supply management function's perceived status are hypothesized as antecedents to supplier integration leading to supply management performance. The sample for this study includes 152 executive level supply management professionals. The empirical results suggest that strategic skills and perceived status are essential antecedents to supplier integration and subsequent performance. Further, the relationship between strategic skills and performance is mediated by supplier integration. Results of a dominance analysis also suggest which strategic skills are most likely to explain status integration, and performance. These findings have significant implications for supply management theory and practice. 相似文献

The European Union (EU) nutrition labelling policy aims to facilitate consumers’ food choice, stimulate innovation and facilitate the circulation of foods bearing claims across countries. However, the beef industry has not fully taken advantage of utilizing nutrition and health claims based on the EU nutrition labelling policy to differentiate beef products in the market. This study investigates consumer preferences for nutrition and health claims on lean beef steak. Two choice experiments were conducted among 2400 beef consumers in four EU countries (Belgium, France, the Netherlands, United and United Kingdom). Multinomial logit and error component models were estimated. Our results generally suggest that consumer valuation of nutritional and health claims varies across countries. In Belgium, the Netherlands and France, nutrition and health claims on saturated fat yielded higher utilities than claims on protein and/or iron, while the opposite was found among consumers in the UK. The results imply that marketing opportunities related to nutrition and health claims on beef are promising, but that different nutritional marketing strategies are necessary within different countries. 相似文献

Current debates around robotics and artificial intelligence (AI) are dominated by concerns over the threat to employment, amid widely varying estimates of potential job losses. Countries are expected to fare differently, but there is little comparative research that goes beyond analysing industry and occupational structures. This article rethinks ‘country effects’ by exploring the role of institutions and social actors in shaping technological change in Norway and the UK. Drawing upon interviews with technology experts, employer associations and trade unions, it examines their perspectives on public policy support for the development and diffusion of robotics and AI, along with potential consequences for employment, work and skills. The research indicates significant country differences and the continued relevance of institutions, interests and power in analysing country effects. 相似文献

New new technologies: the future and the present of work in information and communication technology
Ursula Holtgrewe 《New Technology, Work and Employment》2014,29(1):9-24
This paper outlines a selection of technological and organisational developments in the information and communication technology (ICT) sector and analyses their likely challenges for workers and trade unions around the globe. It addresses the convergence of telecommunications and information technology, the related developments of ubiquitous computing, ‘clouds’ and ‘big data’, and the possibilities of crowdsourcing and relates these technologies to the last decades' patterns of value chain restructuring. The paper is based on desk research of European and international sources, on sector analyses and technology forecasts by, for instance, the European Union and Organisation for Economic Co‐operation and Development, and some national actors. These prognoses are analysed through the lens of recent research into ICT working environments and ICT value chains, identifying upcoming and ongoing challenges for both workers and unions, and outlining possible research perspectives. 相似文献

The field of artificial intelligence (AI) is experiencing a period of intense progress due to the consolidation of several key technological enablers. AI is already deployed widely and has a high impact on work and daily life activities. The continuation of this process will likely contribute to deep economic and social changes. To realise the tremendous benefits of AI while mitigating undesirable effects will require enlightened responses by many stakeholders. Varying national institutional, economic, political, and cultural conditions will influence how AI will affect convenience, efficiency, personalisation, privacy protection, and surveillance of citizens. Many expect that the winners of the AI development race will dominate the coming decades economically and geopolitically, potentially exacerbating tensions between countries. Moreover, nations are under pressure to protect their citizens and their interests—and even their own political stability—in the face of possible malicious or biased uses of AI. On the one hand, these different stressors and emphases in AI development and deployment among nations risk a fragmentation between world regions that threatens technology evolution and collaboration. On the other hand, some level of differentiation will likely enrich the global AI ecosystem in ways that stimulate innovation and introduce competitive checks and balances through the decentralisation of AI development. International cooperation, typically orchestrated by intergovernmental and non-governmental organisations, private sector initiatives, and by academic researchers, has improved common welfare and avoided undesirable outcomes in other technology areas. Because AI will most likely have more fundamental effects on our lives than other recent technologies, stronger forms of cooperation that address broader policy and governance challenges in addition to regulatory and technological issues may be needed. At a time of great challenges among nations, international policy coordination remains a necessary instrument to tackle the ethical, cultural, economic, and political repercussions of AI. We propose to advance the emerging concept of technology diplomacy to facilitate the global alignment of AI policy and governance and create a vibrant AI innovation system. We argue that the prevention of malicious uses of AI and the enhancement of human welfare create strong common interests across jurisdictions that require sustained efforts to develop better, mutually beneficial approaches. We hope that new technology diplomacy will facilitate the dialogues necessary to help all interested parties develop a shared understanding and coordinate efforts to utilise AI for the benefit of humanity, a task whose difficulty should not be underestimated. 相似文献
