Based on the proactive motivation model, this study incorporates four moderating variables: leader-member exchange, team member exchange, citizenship pressure, and career agility. An integrated framework is developed to explain the transformation from voice intention to voice behavior, drawing on three types of motivational forces: “reason to” “can do” and “energized to”. Using a two-wave survey design, a total of 366 valid responses were collected and analyzed. The results reveal a moderate positive correlation between voice intention and voice behavior. Leader-member exchange and team member exchange, as sources of “can do” motivation, enhance the positive influence of voice intention on voice behavior. Meanwhile, citizenship pressure and career agility, serving as sources of “energized to” motivation, exhibit distinct moderating effects. Specifically, citizenship pressure demonstrates an inverted U-shaped effect on the relationship between voice intention and voice behavior, whereas career agility shows a positive moderating effect on this relationship.
