Public Service Values and Motivation as Predictors of Two‑Dimensional Innovative Behavior: The Moderating Roles of Procedural and Distributive Justice

(Purpose) This study examines how public service values and public service motivation (PSM) shape individual‑level innovative behavior in public organizations, distinguishing a two‑dimensional outcome: proactive(motive) behavior and silence(acquiescent/defensive). We also test whether organizational justice—procedural and distributive—conditions these relationships. (Design/methodology/approach) Using the 2024 Korea Institute of Public Administration Civil Service Life Survey (n = 6,075), we estimate stepwise OLS models with robust standard errors and mean‑centered continuous predictors, controlling for agency type, gender, age, education, tenure, entry type, and rank. (Findings) Findings are as follows. First, for proactive behavior, democratic, professional, and ethical values show significant positive associations. All four PSM facets—attraction to policy making, self‑sacrifice, compassion, and commitment to the public interest—are also positively related. Procedural justice exhibits a positive main effect, whereas distributive justice is not significant. In moderation tests, procedural justice amplifies the effect of democratic values but attenuates the effect of professional values; distributive justice strengthens the effect of ethical values while weakening that of professional values. Second, for silence, democratic values and two PSM facets (commitment to the public interest, attraction to policy making) are associated with lower silence. Procedural justice is the strongest suppressor of silence, while distributive justice is modestly associated with higher silence. Moderation patterns indicate that procedural justice strengthens the “values → lower silence” pathway for professional and humanistic values but weakens it for democratic values; distributive justice similarly strengthens suppression of silence for professional and humanistic values while attenuating it for democratic values. (Research implications or Originality) Overall, the study demonstrates asymmetric effects of the same predictors across the two dimensions of innovative behavior, highlights the centrality of democratic values, and documents the dual role of procedural justice as both a direct driver and a contextual moderator.
