Sustained green innovation in firms is a crucial driver of sustainable economic development. Chief executive officer (CEO) openness, as a key personality trait related to leadership effectiveness, has an important but largely overlooked impact on sustained green innovation. This study aims to explore the impact of CEO openness on sustained green innovation and its boundary conditions. Using data from Chinese A-share-listed firms between 2011 and 2023, we find that CEO openness has a significant positive impact on sustained green innovation in firms. The moderating effects reveal that both digitalization level and CEO shareholding strengthen the positive effect of CEO openness on sustained green innovation. Heterogeneity analysis indicates that this positive effect is more pronounced in state-owned enterprises, firms in non-heavily polluting industries, and those with high analyst coverage. These findings provide theoretical support for understanding the determinants of sustained green innovation through the lens of CEO personality. They also enrich the growing literature on the impact of CEO openness on corporate decision-making. Furthermore, this study recommends that firms prioritize CEO openness in selection, enhance digital infrastructure, and improve equity incentive measures to ultimately foster sustained green innovation.

In the process of government management, officials may engage in rent-creation and rent-seeking within finance and debt management for personal gain, leading to corruption and jeopardizing government debt sustainability. Can anti-corruption effectively ameliorate this predicament? Based on the growing severity of global debt sustainability, 30 provincial-level administrative regions in China are used as research samples to explore the influence of China’s anti-corruption campaign targeting officials on local government debt sustainability and the moderating role of fiscal transparency. The results indicate that enhancing anti-corruption efforts will improve the sustainability of local government debt, while fiscal transparency will magnify this positive impact. Furthermore, regional heterogeneity analysis demonstrates that, in developed regions, the impact of anti-corruption on debt sustainability and the moderating impact of fiscal transparency have been bolstered by effective policy implementation. Our research findings not only unveil the influence of anti-corruption on local government debt sustainability and the crucial role of fiscal transparency, but also offer fresh insights to enable local government authorities to manage debt sustainably.
