利用扎根理论方法,以吉利汽车为例,对吉利汽车通过全球研发、跨国联盟、内部修炼等在创新合作网络发展的不同时期所占据的不同网络位置与创新绩效的关系进行了研究,并分析了企业家精神在两者间的中介作用。结果表明:占据网络中介和富含结构洞的网络位置能使企业获得更高的创新绩效;在两种不同的网络位置——中心位置和中介位置与创新绩效的关系中,企业家精神均起中介作用。  相似文献

基于多指标决策方法在新能源发电绩效评价领域应用的广泛性,本文分别从评价指标、指标权重及评价方法三个方面对现有新能源发电绩效评价相关文献作了回顾与总结。在评价指标上,分别从技术、经济、环境和社会方面总结了常用的新能源发电绩效评价指标;在指标权重上,分别从主观权重、客观权重和混合权重三个方面对权重设置进行了分析;在评价方法上,分别对AHP、TOPSIS和PROMETHEE等方法在新能源发电绩效评价中的应用进行了分析。同时,本文还指出了现有新能源发电绩效评价研究的不足及可进一步拓展的研究方向。  相似文献

文章以重庆大中型工业企业2000-2011年数据为样本,实证研究了细分技术源和政府补贴的创新绩效影响。结果表明:内部RD、技术改造和国内技术购买均可提升创新绩效,其中技术改造的创新绩效正影响最大;国外技术引进对创新绩效的直接影响显著为负,但国外技术引进与技术改造和国内技术购买存在显著的正向互动关系,说明国外技术引进需与技术改造和国内技术购买结合才能提升创新绩效;政府补贴可刺激企业扩大内部RD和技术改造而提升创新绩效,但难以影响企业国内外技术引进的决策。因此,技术改造对提升创新绩效最有效。  相似文献

In this paper, we propose a national competitiveness index using raw Institute of Management Development (IMD) data and try to overcome a shortcoming in the IMD's own ranking system. The IMD world competitiveness ranking considers 20 factors to define an index, but it does not consider the structural relationships among various factors. We utilise a structural equation model to derive a national competitiveness index that reflects such structural relationships. We then reveal new rankings of world competitiveness. In addition, we conducted a comparison analysis by economy level and identified improvement points in terms of measurement variables as well as latent variables. Our work is expected to promote a new era of national competitiveness rankings and indices.  相似文献

In this study, an organization means an active actor that can, at least to some extent, adapt to the environment, mainly within the limits of its resources and capabilities. The article enhances understanding of and explains organizational adaptive behavior in weathering the storm in the business environment resulting from the global financial crisis of 2008. The literature on dynamic capabilities, organizational change, and innovation in the context of organizational performance and survival captures this kind of adaptive behavior. The empirical study builds on a quantitative survey and a qualitative case study covering the food processing, maritime, and media industries. Structural equation modeling, group analysis, and qualitative case comparisons shed light on the connection between the constructs in question. Implications for theory and practice culminate in suggestions for future research.  相似文献

This study assesses the relationship between organizational innovation and technological innovation capabilities, and analyzes their effect on firm performance using a resource-based view theoretical framework. The article presents empirical evidence from a survey of 144 Spanish industrial firms and modeling of a system of structural equations using partial least squares. The results confirm that organizational innovation favors the development of technological innovation capabilities and that both organizational innovation and technological capabilities for products and processes can lead to superior firm performance.  相似文献

This paper examines the etic vs. emic nature of the new product creativity (NPC) construct often used in the strategic marketing and management literatures. The current study compares the NPC measure developed by Im and Workman (2004) in the West in an Eastern context by utilizing data from 172 Malaysian companies. The results show that NPC, which is the combination of new product (NP) novelty and NP meaningfulness, has a different connotation in Malaysia. The findings demonstrate that from the novelty perspective NPC is an emic phenomenon. After the construct validation process, the Western claim that NPC is a seed of firm performance is tested. The results verify NPC's relationship with NP performance as a source of competitive advantage for Malaysian firms and thus suggest that this relationship is etic in nature. These findings have significant implications for firms' global innovation strategies.  相似文献

Abstract

This article, based in the body of strategic orientation literature, identifies and explores the practices of innovativeness, proactiveness and competitive aggressiveness that make up the strategic orientation implemented by subsistence entrepreneurs to improve business performance. A factor analysis was carried out using the data of 101 entrepreneurs, small artisanal business owners who operate in the subsistence markets in Oaxaca, Mexico. The results show that subsistence entrepreneurs notably engage in innovative and proactive practices, and, to a lesser extent, competitive aggressiveness. The research concludes that a combination of innovativeness with proactiveness is the most viable option for improving performance, whereas competitive aggressiveness impedes its development. Even so, however, it is still implemented by subsistence businesses in order to conserve their market share.  相似文献

压缩感知为认知无线电的宽频谱感知提供了一种新的方法和思路。基于压缩感知的原理,提出了一种多认知用户协作场景下基于用户统计可信度的协作频谱检测算法。该算法使用正交匹配协作追踪算法获得认知区域内的频谱占用情况,根据不同认知用户频谱检测的历史准确度综合判定用户感知结果的统计可信度。仿真结果表明,该算法在不同用户数、不同采样值、不同信噪比变化范围下其检测性能均优于传统算术平均方法,有效改善了检测性能。  相似文献
