New employees can bring new perspectives and vitality to the organization. Creating a suitable environment for new employees to innovate, maintain their work enthusiasm, and stimulate their innovative behavior is an important research topic. This study focused on recent college graduates and included 893 valid samples collected from Chongqing, China. A structural equation model was constructed from a multidimensional perspective to explore the mediating role of employee engagement between person-environment fit and new employees’ innovative behavior. The results show that person organization fit, needs supplies fit, and demands abilities fit can directly increase new employees’ innovative behavior; Emotional and behavioral engagement mediate the relationship between person organization fit and needs supplies fit on innovative behavior, and behavioral and cognitive engagement mediate the relationship between demands abilities fit on innovative behavior. This provides practical suggestions for enterprise managers on effectively promoting employees’ innovative behavior and leading enterprises to realize sustainable development.

Green innovation is essential for sustainable development, especially in China’s Specialized-Refined-Differentiated-Innovative (SRDI) enterprises. Family-owned SRDI firms, in particular, have attracted attention due to their de-familization strategies and their influence on green innovation. Our study analyzes panel data from 2016 to 2021 for listed SRDI family firms to investigate how de-familization in management rights and ownership impacts green innovation. Using socio-emotional wealth (SEW) theory and a fixed-effects model, we find that de-familization significantly negatively affects green innovation, with corporate governance serving as a mediating factor. Digital transformation moderates these negative effects, while market concentration exacerbates them. These impacts are more pronounced in firms before being designated as "Little Giants," those receiving higher government subsidies, those located in eastern regions, or those not classified as major polluters. This research provides actionable insights for SRDI family firms to strategically manage de-familization, optimize resource allocation, implement customized governance strategies, and promote sustainable growth.
