This study investigates how female employees contribute to firm innovation by applying panel data Poisson regression models to data pertaining to 144 major Japanese manufacturing firms from 2004 to 2022. The results reveal the following: First, there is a positive relationship between longer female employment and innovation. Longer female employment may be attributable to female employees feeling more secure at their workplaces. Second, regarding women's unique perspectives, this study suggests that female participation in innovation may increase the number of technological fields. Third, this study presents the mediating effects of technological fields on the relationship between high-impact innovation and the demographic of female employees. These findings suggest corporate management creates a system that allows female employees to play an active role in the workplace with long-term employment. The empirical results provide new insights into previous literature on corporate innovation, specifically technological innovation.
本研究通过对2004年至2022年144家日本主要制造企业的数据应用面板数据泊松回归模型，调查了女性员工如何为企业创新做出贡献。结果显示如下：第一，女性员工工作年限延长与创新之间存在正相关关系。女性员工工作年限延长可能是因为她们在工作场所感到更有安全感。第二，关于女性独特的视角，本研究表明女性参与创新可能会增加技术领域的数量。第三，本研究提出了技术领域在高影响力创新与女性员工人口统计学特征之间关系中的中介作用。这些发现表明企业管理层应创建一个系统，使女性员工能够通过长期就业在工作场所发挥积极作用。实证结果为以往关于企业创新，特别是技术创新的文献提供了新的见解。
