Abstract

This study explores empirically the underlying mechanism through which organizational flexibility affects the performance of its project portfolio, using innovation capability as a mediator, and examines the moderating role of environmental uncertainty in the relationship between organizational flexibility and innovation capability. Data collected from 201 firms were analyzed using partial least squares structural equation modeling with SmartPLS software. The study shows that organizational flexibility positively affects innovation capability and that innovation capability has a positive impact on project portfolio performance. Further, innovation capability positively mediates the relationship between organizational flexibility and its project portfolio’s performance. The adverse moderating effect of environmental uncertainty on the relationship between flexibility and innovation capability also found. The study contributes to innovation theory by using quantitative data to address the role of flexibility in improving innovation capability and the performance of project portfolios and provides a framework that managers can use to enhance the performance.

摘要

本研究以创新能力为中介，实证探索了组织灵活性影响其项目组合绩效的潜在机制，并检验了环境不确定性在组织灵活性与创新能力之间的关系中的调节作用。从 201 家公司收集的数据通过 SmartPLS 软件使用偏最小二乘结构方程模型进行分析。研究表明，组织灵活性对创新能力有正向影响，而创新能力对项目组合绩效有正向影响。此外，创新能力正向调节组织灵活性与其项目组合绩效之间的关系。还发现了环境不确定性对灵活性和创新能力之间关系的不利调节作用。该研究通过使用定量数据来解决灵活性在提高创新能力和项目组合绩效方面的作用，为创新理论做出了贡献，并提供了管理者可以用来提高绩效的框架。
