Opening the Black Box of Upper Echelons in China: TMT Attributes and Strategic Flexibility

Many scholars have suggested that strategic flexibility is a critical firm capability to survive in today's competitive arena. The decision to take strategic actions to make the firm more strategically flexible typically originates in the top management team (TMT). As the principal decision‐making unit of the firm, TMT members' information acquisition and processing capabilities and subsequent interpretation of environmental changes critically influence the decision to make the firm more strategically flexible to achieve a better fit with its market environment. Therefore, in order to understand how firms can adapt to environmental changes, scholars must study the sociopsychological processes of interaction among members of the TMT. This study examines the relationships between TMT's sociopsychological attributes (shared vision, social integration, and political ties) and strategic flexibility, which is decomposed into organizational flexibility and technological flexibility. The study further investigates how the level of competitive intensity can moderate the relationships. All the hypotheses are tested using structural equation models based on the survey data from 227 firms in China. The results show that organizational flexibility mediates the impact of TMT's social integration and political ties on technological flexibility. Surprisingly, a TMT's shared vision for the firm neither impedes nor facilitates the firm's effort in attaining the desired degree of organizational flexibility. However, TMT's shared vision does have a positive and direct impact on technological flexibility. Moreover, intense competition amplifies the positive impact of TMT social integration on the degree of organizational flexibility, but there is no significant moderating effect of competitive intensity on the relationship between a TMT's political ties and organizational flexibility. The results extend previous research by highlighting the importance of TMTs' sociopsychological attributes in driving technological flexibility, through the mediating impact of organizational flexibility.     

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.     

产品开发中企业引入消费者参与的时机决策：一个基于消费者偏好信号传递的分析

针对“企业可以在产品开发的不同阶段引入消费者参与”的实践观察，本文构建消费者与企业之间的不完全信息动态博弈模型来研究“在何种条件下，企业选择产品开发前端（后端）引入消费者参与，从而激励消费者真实传递其偏好信息”这一问题。研究表明：存在外生参数（消费者讨价还价能力和参与净效用表征），使得前端和后端引入消费者参与均（或二者中只有一个）能够实现消费者真实传递其偏好信息的分离均衡；前端参与时，分离均衡要求企业通过新产品价格分担（攫取）消费者的负（正）参与净效用，而后端参与不需要这种分担（攫取）机制；在前端和后端参与均能实现消费者真实传递其偏好时，前者优于后者的条件是参与净效用为正。

地位竞争动机对个体知识共享行为的影响

知识共享行为是学术界和企业界关注的焦点，虽然以往文献从多个角度和层次研究了组织中的知识共享行为，但忽视了地位竞争动机对个体知识共享决策的内在作用机制。基于地位竞争动机差异，将个体地位动机区分为支配型和威望型，以职场排斥为中介变量、组织公平氛围为调节变量，构建地位竞争动机对知识共享行为的影响过程模型，基于13个组织630套上下级配对样本数据进行实证检验。结果显示，支配型地位竞争动机负向影响知识共享行为，威望型地位竞争动机正向影响知识共享行为，职场排斥、组织公平氛围分别发挥中介效应和调节效应。结果为知识共享领域研究提供了新的视角和框架，揭示了地位竞争动机对知识共享促进和抑制作用的两面性，对企业管理实践有一定的现实意义。     

The Chinese Stock Dividend Puzzle

In this paper, we examine the announcement effects of dividends with an emphasis on stock dividends in China's capital market. We find that dividend-paying stocks exhibit significantly positive abnormal returns while non-dividend-paying stocks show a negative announcement effect. Further, we document that the cumulative abnormal returns for pure stock dividends and combined dividends are the main drivers of this announcement effect. In contrast, pure cash dividend stocks experience no significant price run-up before announcement. The significant announcement effect of stock dividends is robust to controlling the earnings surprise effect. We offer some discussion of the possible explanations.     

零工经济时代数字平台控制劳动力的供给行为

本文首先基于委托-代理模型构建了一个数字平台控制劳动力供给的行为经济学模型,从理论上分析了数字平台控制劳动的方式和心理机制;然后建立了一个赫克曼(Heckman)选择模型,利用Uber的大数据实证分析了网约车司机的劳动决策.研究结果表明:(1)在零工具有参考点偏好的前提下,数字平台通过高货币激励或高目标奖励使零工劳动者的参考点具有适应性,进而避免其过早地陷入“收入目标”行为;(2)数字平台利用零工劳动者的厌恶损失偏好,对其实施控制以延长工作时间;(3)网约车司机存在“收入目标”行为,且该行为呈现出动态性的特点;(4)收入激励和“峰时”溢价对网约车司机的工作概率和工作时间具有显著的正影响,且在一天的某个时间段内能够抑制网约车司机的“收入目标”行为.可见,零工经济时代到来,一方面提高了劳动力资源配置效率;另一方面,数字平台通过劳动控制变相延长了零工的劳动时间,加剧了剥削.     

加强政策事中事后评估的思考

党的十九届四中全会明确提出要强化决策执行、评估、监督,做好政策评估对优化政府职能、推动国家治理体系和能力现代化有积极作用。加强政策运行情况的评估,应从优化评估工作机制、完善和培育评估机构、强化评估结果的应用入手,不断提升评估工作质量,形成适应中国特色社会主义现代化治理体系的事中事后政策评估机制。
