职场友谊对研发团队创新绩效的影响机制研究——一个带中介的调节模型

本文通过问卷调查法获得372份有效问卷,运用带中介的调节模型探讨了职场友谊对研发团队创新绩效的影响机制。实证结果表明：（1）职场友谊对团队创新绩效是有正向的激励作用的,其中知识分享起中介作用;（2）职场友谊对团队创新绩效的作用同时受到员工知识分享意愿和知识分享能力的中介作用;（3）职位级别对职场友谊通过知识分享对团队创新绩效的影响起负向调节作用,即职位级别越高,友谊机会越小,通过员工友谊促进知识分享,进而提高团队创新绩效的效应越低。     

Localization and overseas R&D activity: the case of Taiwanese multinational enterprises in China

This study investigates the determinants of overseas research and development (R&D) and the influences of various aspects of localization on affiliates' R&D intensity. Using a dataset of Taiwanese multinational enterprises (MNEs) in China, the empirical estimations find that MNEs with a larger firm size, more R&D expenditure, and a higher outward foreign direct investments intensity tend to undertake R&D. Host regions' characteristics, particularly market size and R&D resources, do matter for attracting MNEs to conduct R&D locally. Crucially, affiliates' R&D intensity is related to the degree of localization. The degree of market localization and localization of the R&D network has a positive association with affiliates' R&D intensity. From the perspective of R&D policy, a country with healthy R&D infrastructures helps attract the establishment of R&D labs of MNEs.     

Opportunity recognition and SME performance: the mediating effect of business model innovation

Opportunity recognition is vital for small and medium-sized enterprises (SMEs), but SMEs face challenges in capturing recognized opportunities. Given that opportunity recognition does not automatically lead to higher SME performance and that SMEs need to take appropriate actions to exploit recognized opportunities to achieve better performance, it is imperative to explore the mediators that enable SMEs to translate opportunity recognition into higher performance. This study proposes that business model innovation may be a key conduit through which opportunity recognition affects SME performance. Based on a dataset of 155 SMEs, we find that the positive relationship between opportunity recognition and SME performance is mediated by business model innovation. These findings not only aid SMEs in accomplishing the performance effect of opportunity recognition, but also provide some insights into the implications of business model innovation.

浅谈企业执行力的培养

在核心竞争力、学习型组织之后,现在执行力又成了一个人们关注的管理话题。很多管理者都乐于布置任务、做决定,但真正有效的管理者却是擅长使布置下去的任务和做出的决定得以执行。按现在正在流行的说法,就是能够让自己的企业有“执行力”。一、执行力是企业成功的关键有人说,一个企业的成功,30%靠战略,30%是运气,另外40%就是靠执行力。执行力到底重不重要?正像新近出版的《执行力》一书中所指出的那样,“我们看到满街的咖啡店,惟有星巴克一枝独秀;同是做P C,惟有戴尔独占鳌头;都是做超市,惟有沃尔玛雄居零售业榜首。”各家便利商店和咖啡…

Is sin always a sin? The interaction effect of social norms and financial incentives on market participants’ behavior

Using alcohol, tobacco, and gaming consumption data and people’s attitudes toward these sin products to proxy for social norm acceptance levels, we show a strong interaction effect between social norms and financial incentives, which significantly influence the behavior of market participants. Specifically, institutional investors’ shareholdings and analyst coverage of sin companies increase with the degree of social norm acceptance. The association between shareholdings/coverage and social norm acceptance is less pronounced for firms with higher future expected performance. Our results show that social norms and financial incentives have a powerful interaction effect in determining the behavior of market participants, suggesting that social norms can be crossed when motive and opportunity exist.
