基于"星形模型"的中小企业区域竞争力研究——关于中部六省的实际测算

中小企业竞争力作为区域竞争力提升中不可忽视的力量,已愈来愈受到人们的重视。文章以中小企业竞争力和区域竞争力理论为出发点,提出了中小企业区域竞争力概念,并在回顾波特国家钻石模型的基础上,提出了中小企业区域竞争力星形模型,同时将其应用于中部六省的中小企业区域竞争力的测算中,检验了模型的有效性和实用性。     

Impact of star and movie buzz on motion picture distribution and box office revenue

This study contributes to research on the impact that consumer buzz has on movie distribution and box office success by examining the impact of buzz generated about the individual stars and about the movie itself. The results indicate that movie buzz is instrumental in boosting box office revenue throughout the theatrical release, not just in the later run, as has been suggested in previous studies. Star buzz can enhance box office receipts during the opening week and can contribute to the public's anticipation of the movie pre-release. However, early buzz can have a negative impact on revenue during subsequent weeks if the movie fails to resonate with the audiences. Model simulations reveal that, even for poorly received films, the overall impact of star buzz is positive because the initial revenue boost normally outweighs the later decline. Thus, this study empirically demonstrates the positive impact of star buzz on revenue, which helps shed light on the long-standing debate regarding the importance of star participation in the success of a movie.

From the blogosphere into the parliament: The role of digital technologies in organizing social movements

In this paper, we present a process model exploring the roles played by digital technologies (DTs) in the organization of collective action (CA) of social movements (SMs) at different points in their lifecycles. The process model, which is based on an exploratory case study of the Italian Five Star Movement, relates the environmental conditions to the working logic, structure and use of DTs at three different stages of the SMs. We explain how these choices are adopted at each stage to address internal and environmental challenges and how they create further challenges to be addressed to pass to the next stage. We further explore the dynamics between the logic of connective and collective action and reflect on the growing need for structures and control. By so doing, our work addresses the need for a better understanding of the coevolution between DTs and organizational structures and of the ways in which DTs are used to mobilize people to sustain CA along the SM lifecycle.     

Rise and fall of stars: Investigating the evolution of star status in professional team sports

This article describes an empirical study of the rise and fall of star athletes, using data from the National Basketball Association (NBA) from 1987 to 2008. We measure star status by the number and share of all-star votes, and we apply both Tobit regression and hazard models to investigate the determining factors for star status. We find that the attainment of star status begins with the athlete's exceptional individual performance. We also find that having won a championship in the past can have a long-lasting effect on a player's popularity. The popularity of an athlete depends on his team in two ways: the attainment of star status is associated with strong team performance, and star teammates can reinforce each other's popularity. Interestingly, whereas stars can move from a losing team to a winning team to extend their star life, a team change can be very risky for new stars. Our results also suggest that teams with a large fan base, winning records, and star players should leverage these assets in attracting and retaining star players.

明星发明人识别与角色分析:来自机器学习领域的实证

明星发明人有助于提高企业研发创新绩效。目前对明星发明人的地位与功能探讨不足，导致企业无法全面掌握发明人信息，难以为研发活动招聘合适的人才。鉴于此，对机器学习领域明星发明人的领导、传播、知识或任务排他等功能和地位进行识别，采用动态网络分析方法确立六类明星发明人，即焦点型发明人、领导型发明人、潜在跨界型发明人、传播型发明人、任务排他型发明人和知识排他型发明人，分析其角色功能。结果表明：部分发明人同时拥有多种地位；领导型、焦点型和知识排他型明星发明人影响范围更广、职业流动性更强，与其他发明人的交互时间更长；隔离同时具有3种地位的明星发明人对焦点型发明人影响显著。

基金现金流、明星基金与溢出效应

本文建立动态面板数据模型,运用系统广义矩(System GMM)方法对基金现金流和基金业绩、明星基金和溢出效应的关系进行考察。结果发现,无论是从单只基金层面还是从基金系层面,基金(基金系)现金流都与基金(基金系)业绩呈显著负相关。对明星基金本身来说,表现为净现金流出;但明星基金为同属一个基金系的其他成员基金带来显著的正向溢出效应。另外,从基金系角度看,虽然存在溢出效应,明星基金的存在并没有给整个基金系带来显著的现金流入,说明基金系的造星策略并不十分有效。
