Growing user base in the early stage of sharing economy platforms: An integration of competitive repertoire and institutional legitimacy theories
Growing user base in the early stage of sharing economy platforms: An integration of competitive repertoire and institutional legitimacy theories
Sharing economy platforms are pressed to rapidly grow user bases at the early stage by aggressively targeting potential users through competitive actions. Due to the volatile nature of the sharing economy and its disruption to industry norms, these platforms encounter legitimacy challenges that impede user base growth. This paper integrates competitive repertoire and institutional legitimacy theories to develop a research model that explains early-stage user base development in the sharing economy. We posit that the early-stage user base is associated with structural characteristics of the competitive repertoire, whose effects are moderated by a platform's socio-political legitimation efforts that address stakeholders’ regulatory and normative concerns. Using a comprehensive sample of 4644 monthly observations of 129 sharing economy platforms in China, we find that the volume of two context-specific competitive actions, offering economic incentives and staging high-visibility events, along with competitive repertoire complexity, are positively related to the platform's early-stage user base. We also identify a significant negative relationship between repertoire differentiation and user base. Direct relationships are moderated by socio-political legitimation, however, such that legitimation weakens the positive impact of context-specific action volume but enhances those of repertoire complexity and differentiation. Managerial and practical implications are discussed in light of the findings.

Pushing Yourself Harder: The Effects of Mobile Touch Modes on Users’ Self-Regulation
Pushing Yourself Harder: The Effects of Mobile Touch Modes on Users’ Self-Regulation
Many mobile applications use push notifications and reminders to explicitly educate, remind, and motivate users to perform healthy behaviors. However, users do not always act according to these explicit digital interventions. Our study investigates whether users’ self-regulation can be implicitly facilitated with a proper mobile interaction design. Specifically, we investigate the impacts of two touch modes that are supported by force-based interaction technology, that is, pressing and tapping. Drawing on the theory of embodied cognition, which suggests that people automatically infer meanings from their bodily actions, we conjecture that pressing, compared with tapping, enhances self-regulation because the action of pressing on the touchscreen embodies resolute approach motivation toward goals. We test our hypotheses in three experiments. The first experiment investigates beverage choices on a mobile app; the second experiment examines goal setting on a fitness app; and the third experiment focuses on personal hygiene learning on a mobile education app. The results from the three experiments show that pressing actions can improve users’ self-regulation in selecting a healthier but less tasty beverage (Study 1), setting higher exercise goals and performing more physical exercise (Study 2), and reducing lapses in maintaining personal hygiene (Study 3). In addition, such effects were more salient among users with a higher level of health knowledge and a promotion-focused health orientation. This study contributes to healthcare IT research by showing that mobile interaction can be leveraged to nudge users toward enhanced self-regulation.

整合分析:拉引營銷活動對多元渠道企業進行有效營銷的影響
整合分析:拉引營銷活動對多元渠道企業進行有效營銷的影響
是項研究為一個針對拉引營銷活動如何影響多元渠道企業有效地推行營銷活動的整合分析。高度靈活的拉引營銷活動,目標是令多元分銷渠道組合更具吸引力。作者透過整合以往的多元渠道分銷文獻,研究營銷活動是否有效,與拉引營銷活動及其分銷渠道結構的配置,以及客戶、競爭及產品類別的關係。是項分析結合研究樣本的企業、數據和模型屬性,發現當多元渠道企業在所有分銷渠道中使用數碼廣告和價格促銷時,營銷活動更有效。跨渠道價格歧視並不會令營銷活動更有效。此外,數碼廣告和價格促銷是否配合多元化的渠道、渠道的豐富性、客戶體驗、市場競爭力和產品消費頻率,也會對有效推行營銷活動造成影響。

How to Recover from Work Stress, According to Science
How to Recover from Work Stress, According to Science
To combat stress and burnout, employers are increasingly offering benefits like virtual mental health support, spontaneous days or even weeks off, meeting-free days, and flexible work scheduling. Despite these efforts and the increasing number of employees buying into the importance of wellness, the effort is lost if you don’t actually recover. So, if you feel like you’re burning out, what works when it comes to recovering from stress? The authors discuss the “recovery paradox” — that when our bodies and minds need to recover and reset the most, we’re the least likely and able to do something about it — and present five research-backed strategies for recovering from stress at work.

數字平台有偏見 草根經濟難創新
數字平台通過降低消費者的搜索成本,有助於知名度不高的文化工作者找到知音,讓在傳統市場乏人問津的產品能以較低成本進入市場,令市場百花齊放。然而,在「流量為王」的時代,平台運營日趨偏頗,尤其是在中國的數字文藝娛樂市場,平台的推送和操縱能決定一部作品的命運,甚至窒礙產業創新。

Taste of Free Lunch: The Impact of Free Product Disclosure on Review Dynamics
世上真的有「免費午餐」嗎?一些網購平台容許消費者撰寫評論時,以自願性質披露產品是否由商家免費送贈或提供折扣。這些免費標籤評論佔比不高,但後續引發的連鎖效應,卻能促進一些評論匱乏的網上社群活躍起來。當免費標籤評論不夠客觀時,會激發線上社群的自我調整機制,促使更多用戶發表更充分、公正的評論。相比於聘請專家撰寫評論,自願披露政策能以較低成本有效提升評論社區的活力。

時至今日,面對紛繁複雜的環境、社會和治理(ESG)指標和日益豐富的ESG實踐,ESG已不再是企業的邊緣議題。 以往企業通常根據不同評級機構的標準來提升其ESG評級。然而,全球約有600家不同的ESG評級機構,各自標準不一,導致評級結果不一致,這意味著即使企業在ESG方面投入大量精力,也可能獲得不同的評級結果。

特朗普当选,香港将受关税上升影响,企业却已做好应对
港大經管學院金融学講座教授陈志武表示,香港经济必然受到影响,因为美国可能会提高对中国商品的关税,并加强对技术轉移。但他预计新关税上限将设定在60%。 教授指出,特朗普的主要支持者之一、科技亿万富翁埃隆·马斯克,可能在特朗普的第二任期内对与中国相关的政策制定起到缓和作用。他还预计,北京将采取更积极的刺激措施,以应对更大的地缘政治不确定性。
