Abstract: Objective To understand the situation of the current job stability of aerospace system medical workers,explore the relationship between job satisfaction in organizational commitment and willingness to leave,and provide a theoretical basis for improving the working environment of aerospace system medical workers in the future to improve the stability of the aerospace system medical workforce. Methods From January to March 2024,a cluster sampling method was used to investigate aerospace system medical workers in Beijing,and the organizational commitment scale,job satisfaction scale and willingness to leave scale were used as the research tool to qualitatively and quantitatively describe the organizational commitment,job satisfaction and willingness to leave of the survey object,and the influencing factors of the willingness to leave were analyzed using multiple linear regression model,and the mediating role was examined by the bootstrap method. Results The total scores of organizational commitment,job satisfaction,and willingness to leave were （91.43±15.82）,（60.38±21.84） and （10.49±4.70）points,respectively.Ideal commitment and job satisfaction were statistically significant predictors of willingness to leave among healthcare workers in the aerospace system（both P<0.01）.The mediating effects of job satisfaction between affective and normative commitment and willingness to leave were -0.069（95%CI：-0.084--0.056） and -0.082（95%CI：-0.095--0.072）,which accounted for 54.76%and 65.60%of the total effect,respectively. Conclusion Affective commitment and norms of healthcare workers in aerospace systems have a negative effect on turnover intentions,and job satisfaction partially mediates the relationship between ideal commitment and turnover intentions.Healthcare system managers can improve the satisfaction of healthcare workers in the aerospace system in terms of affective and normative aspects such as training and competition,work pressure,and satisfaction and sense of belonging to their affiliation for different characteristics such as marital status and education level to reduce brain drain.
