In recent years, with sustainable development strategies, the conflict between economic development and natural resources has become increasingly severe. Meanwhile, green finance’s emergence is due to the rethinking of human economic activities under global warming conditions and the energy crisis. Thus, this study aims to analyze the relationship between green finance and enterprise green performance using a meta-analytic approach. This study has used Comprehensive Meta-Analysis Software (CMA) 2.0 for meta-analysis and applied the Hunter and Schmidt model for statistical analysis to test the proposed hypotheses. This study finds a significant positive correlation between green finance and enterprise green performance and proves that firm type and region play a moderating role in the relationship between green finance and enterprise green performance. However, profitability does not significantly moderate the relationship between green finance and enterprise green performance.

Purpose: To improve unsafe workplace of Chinese SMEs, this paper aims to use the multi-agent simulation experiment to reveal the relationship between employees’ safety voice and safety level of enterprises. Design/methodology/approach: Through simulation of employees’ safety voice activities, enterprises’ production activities, enterprises’ safety activities, an experiment platform is built. The experiment introduces external variable of labor resource and sets four experimental situations considering whether labor resource is sufficient and whether employees’ value is significant. Findings: The result shows that not all the employees’ safety voice can change small- and medium-sized enterprises’ safety level. When there is sufficient labor supply, employee safety voice cannot improve the safety level of enterprises; when there is short of labor and employee safety voice is strong, safety level can be effectively improved. When employees have the strikingly different value variance, safety voice of common employees cannot improve safety level of enterprises, but employee safety voice with high value can improve safety level. Originality/value: This fully provides that under the circumstances of disappearing demographic dividend in China, improving employees’ safety awareness and reasonably using their safety voice can boost SMEs to enhance safety level.
