The emergence of enterprise social media (ESM) allows enterprises to develop employee improvisation ability for effective decision-making in various emergencies. However, it remains unclear how the use of ESM by employees affects their ability to improvise. Based on the job demands-resources model and Kahn's psychological conditions framework, this study constructs a theoretical model capturing two types of ESM usage—work-related and social-related—and examines their impact on employee improvisation ability. Through the analysis of 307 paired data collected from multi-wave and multi-source questionnaires using Smart-PLS software, the results show that both work-related and social-related ESM use can promote employees' psychological meaningfulness, availability, and safety, thus further stimulating employees' improvisation ability. ESM policies only significantly moderated the effects of work-related ESM use on the three psychological conditions of employees. Moreover, there are significant differences in the intensity of the influence of the two types of ESM uses on the psychological conditions of employees. This study not only enriches and promotes the existing research on ESM usage, psychological conditions, and employee improvisation ability but also helps enterprise management effectively guide employees to use ESM to promote their improvisation ability.

企业社交媒体使用通过心理状况对员工即兴发挥能力的影响：企业社交媒体政策的调节作用

企业社交媒体（ESM）的出现使企业能够培养员工的即兴发挥能力，以便在各种紧急情况下做出有效的决策。然而，目前尚不清楚员工使用 ESM 如何影响他们的即兴发挥能力。基于工作需求-资源模型和卡恩的心理状况框架，本研究构建了一个理论模型，涵盖两种类型的 ESM 使用情况——工作相关和社交相关——并检验它们对员工即兴发挥能力的影响。通过使用Smart-PLS软件对多波多源问卷中收集的307个配对数据进行分析，结果表明，工作相关和社会相关的ESM使用都可以提升员工的心理意义、可用性和安全性，从而进一步激发员工的即兴发挥能力。 ESM 政策仅显着减轻了与工作相关的 ESM 使用对员工三种心理状况的影响。此外，两种ESM使用对员工心理状况的影响强度也存在显着差异。本研究不仅丰富和促进了现有关于ESM使用、心理状况和员工即兴能力的研究，而且有助于企业管理层有效引导员工使用ESM来提升其即兴能力。
