This study investigates the connection between corporate social responsibility (CSR) and corporate reputation among the public using fuzzy set qualitative comparative analysis (fsQCA). To examine complex processes underlying the reactions of this influential stakeholder group, hypotheses are drawn from the category diagnosticity approach. Thereby, a psychological model of perceived (im)morality is transferred to the CSR context. In line with these hypotheses, positive/negative CSR activities influence reputation in the expected directions (H1a, b), while the effects of specific configurations of CSR activities reveal an asymmetry suggesting a negativity bias (H2). Further analyses confirm that positive effects require a consistent positive performance regarding prior reputations (H3a) and the aggregated CSR activities of several previous years (H3b, c). Moreover, the relevant patterns vary between industries (H4). The present study thus contributes to CSR research by investigating a powerful but hitherto understudied stakeholder group through a category diagnosticity lens combined with a configurational approach to analysis.  相似文献

根据创新价值链理论,将企业创新活动分为研究阶段(R)与开发阶段(D),探究内外源融资方式对企业不同创新阶段投资的异质性效应,为企业选择创新活动的融资渠道和政府设计精准支持企业创新政策提供参考。基于中国制造业上市公司数据实证研究发现:内源融资对企业研究投资有显著促进效应,对开发投资未产生显著促进作用;债权融资对研究投资和开发投资的作用均不显著;股权融资对研究投资的影响不显著,但对开发投资具有显著影响。内源融资对债权融资与研究投资、债权融资与开发投资的关系不具有调节效应;内源融资对股权融资与研究投资关系具有正向显著调节效应,对股权融资与开发投资的关系具有正向调整作用但不显著。  相似文献

Academic research (rigor) in alignment with practitioners’ challenges (relevancy) has been advocated as a way of overcoming the ivory tower syndrome. Performance measurement is at the heart of strategic management processes, as it provides a mechanism of demonstrating outcomes. Given the importance of this topic for both theory and practice, this article explores the contribution of academic outputs in terms of academic research outputs (rigor) and current practitioners’ needs (relevancy).Using network analysis and cross-citation bibliometric approaches, a sample of 1155 articles is examined and fourteen clusters are identified. The emergent topics and subtopics from the academic literature are compared to ten insights proposed by Ernst Young to the hotel sector. The findings suggest a good fit between the two approaches together with some gaps. Based from empirical results, nine propositions are articulated.  相似文献

In this study we examine the relationship between strategic networks and new product performance from the perspective of ambidextrous innovation (i.e. combining exploratory innovation and exploitative innovation) using a sample of 323 manufacturing firms in the transitional economy of China. Our empirical analyses present several interesting findings: (a) strategic networks are positively related to firms’ new product performance; (b) ambidextrous innovation has a positive effect on firms’ new product performance – that is, the combination of exploratory innovation and exploitative innovation positively affects the firm's new product performance, while the lack of balance between exploratory innovation and exploitative innovation negatively affects the firm's new product performance; and (c) ambidextrous innovation mediates the relationship between strategic networks and new product performance. Our findings provide scholars and managers with a better understanding of the key role played by the simultaneous adoption of exploratory and exploitative innovation in the relationship between strategic networks and new product performance.  相似文献

In light of the growing national priority to develop and revitalise entrepreneurship in emerging economies, our understanding of barriers to serial entrepreneurship (SE) in such a context warrants further scholarly attention. Using insights from Ghana, an integrated framework of endogenous and exogenous barriers to SE is advanced. The study identified factors such as stigmatisation of business failure, fear of failure, successive governments’ suspicion of the private sector and lack of a clear national policy as barriers to the development of SE. By creating conditions for de-stigmatising of failure, countries would be able to create conditions for more serial entrepreneurs to emerge and flourish. The analysis also indicates that reinvigorating entrepreneurship by providing space and opportunity for failed entrepreneurs to re-emerge would enable such countries to enhance entrepreneurial activities and improve economic development. The implications for technology analysis and strategic entrepreneurship literature are identified and examined.  相似文献

The bioeconomy has become a central concept in many strategies for future economic development, emphasising an increasing need for collaboration across industries and sectors for innovation. This paper unpacks aspects of collaboration in the bioeconomy by looking at the development of innovation networks for biorefinery technologies from 2004 to 2014 based on innovation project data from Swedish public funding agencies using a stochastic actor-oriented model for network analysis. The analysis shows that although the network grew significantly during the time period, indicating an increasing interest in biorefinery technology innovation, inter-sectoral collaboration is not favoured over intra-sectoral collaboration. As is known from previous work on social networks trust-building is a key driver for collaboration, as actors tend to form collaborations with previous partners or indirectly connected partners, creating clustered networks.  相似文献

为改善借款方的长期整体发展效果,金砖国家新开发银行对其环境和社会安全保障政策框架进行了大胆创新,着力推进借款方"本国体系"的使用和建设。传统多边开发银行的环境和社会安全保障政策往往采取施加于所有借款方国家法律之上"一刀切"的方式,但难以取得理想的发展效果,其主要原因有:无法影响非多边开发银行资助项目;条件过于僵化,导致部分借款方转而求助于其他融资选项;给借款方造成沉重的时间和费用负担。"本国体系"有效克服了上述难题,但也存在相应挑战。为应对挑战,未来金砖国家新开发银行推进借款国"本国体系"的努力方向是:为本国体系预设一个最低标准;逐步有序而非一步到位地推进本国体系;切实加大对借款方的技术援助。  相似文献

To explore popularly visited tourist locations, travel movement patterns, and movement points, this study collected samples of 321 Chinese tourists and 337 Japanese tourists who were visiting major tourist destinations in Seoul and its vicinity in South Korea. Results of analyzing movement patterns showed that Japanese tourists tend to be clustered around popular attractions, whereas Chinese tourists tend to spread over a larger area of attractions. Some specific shopping and amusement attractions were the locations most popularly visited by both groups. The start points and end points in the two groups’ itineraries were dissimilar overall, even though their patterns were similar in regard to major preferred tourist attractions. Thus, the findings of this study have the potential to contribute to understanding spatial mobility in a tourism destination through tracking tourists’ movement patterns.  相似文献
