Abstract Based on the self-determination theory, the research explores the double-edged sword effect of resilient leadership on employee behavior through 490 questionnaire data collected in three stages. The results show that resilient leadership is positively correlated with taking charge and unethical pro-organizational behavior. Harmonious passion plays a mediating role between resilient leadership and taking charge, and obsessive passion plays a mediating role between resilient leadership and unethical pro-organizational behavior. Environmental uncertainty moderates the relationship between resilient leadership and harmonious passion, and between resilient leadership and obsessive passion. The higher the degree of environmental uncertainty, the stronger the relationship between resilient leadership and harmonious passion. The lower the environmental uncertainty，the stronger the relationship between resilient leadership and obsessive passion
. At the same time, it moderates the mediating effect of resilient leadership on taking charge through harmonious passion, and that of resilient leadership on pro-organizational non-ethical behavior through obsessive passion.
