Abstract：Withtheflateningoforganizationsand theriseofteamcollaboration，employesrole boundaries aregradually bluring.To enhance the innovation capabilityand market competitivenessof enterprises，it is necessary for employees to go beyond fixed job responsibilitiesand develop a broadawareness of \"work roles，\"undertaking avarietyof tasks within the organization.In rapidly changing internal and external environments，ilegitimate tasks have become prevalent in the workplace.However，current disussions onthe impact of illegitimate tasks remain insuficient，particularlyregarding theirinfluence onemploysinnovativebehavior.Asanemerging workcharacteristic，ilegitimate tasks affectemployees job demands and resources，ultimately influencing the generation and implementationof inovative ideas.Existing research is mainly limited toempirical verification orsingle-perspectiveanalysis，making it dificult to deeplyreveal the intrinsic echanismsofillegitimatetasks.Consequently，there isalsoalackof disussiononthecomprehensive moderating effects between job characteristic variables and organizational environment variables.
To expand the understanding of the relationship between ilegitimate tasksand innovative behavior，this study is based on the Job Demands-Resources （JD-R） model and further analyzes the roles of work engagement andjob burnout in the relationship between ilegitimate tasksandemployees‘innovative behavior，whileintroducing work relevanceand moral leadership as moderating variables.The research targets medium-sized enterprises in the Yangtze River Delta region， including Shanghai，Jiangsu，and Anhui，withafocus on high-tech industrial parks.Theindustries areconcentrated inthe information technologyserviceindustry，biopharmaceutical industry，new energy industry，high-endequipment manufacturing idustry，andother fields.Intherapidlydeveloping economic environment，these enterprises facecomplex competitionand innovation pressures，making their employees‘innovativebehaviorand mechanismsfor handling ilegitimate tasks more typical and valuable for research.
This study uses a sample of 585 employes from medium-sized enterprises in the Yangtze River Delta region and constructsa multi-stage moderated dualmediation model.Itisconcluded that，first，ilegitimatetasks positivelyinfluence innovative behaviorby enhancing employees‘work engagement.Second，ilegitimatetasks negativelyimpact innovative behavior through jobburnout.Third，work relevance moderates the effectofillgitimatetasksonemployees‘innovative behavior;specifically，thehigherthe workrelevance，thestronger the positive impactof llegitimatetasks on innovative behavior through work engagement，and the weaker the negative impactofillegitimate tasks on innovative behavior through job burout.Finally，during the moderation processof work relevance，a higherlevelof moral leadership strengthens the positive moderating effectof work relevanceon therelationship betweenillegitimate tasksand innovativebehavior via work engagement and also strengthens the negative moderating efectof work relevanceontherelationship between ilegitimate tasks and innovative behavior via job burnout.
The theoretical contributions of this study lie in three aspects.First，this research enhances the understanding of the positive aspectsofillgitimate tasksbyexploring the“double-edged sword”effctof ilegitimate tasksonemployees'inovativebehavior.Itaddressesthegap inprevious studies thatpredominantly examined thenegative impactsof ilegitimate tasks from a single perspective，ofering a new interpretive angle for comprehending illgitimate tasks from multiple perspectives，especiall the positive pathways.Second，the introductionof workrelevanceas ajobcharacteristic enriches the boundaryconditions inthe researchonillgitimate tasksand employees'innovative behavior.This study moves beyond the limitations of examining boundary influences solelyfrom thelevelsof individualtraitsandcognition，clarifyingunder what circumstances the relationship betwenilegitimate tasksand existing work is more likely to stimulate their positive aspects.Third，this study elucidates theinteraction mechanisms among jobcharacteristics，employee behavior，and leadership behavior byconstructing an integrated model moderated by both moral leadershipand work relevance.Theresearch notonlyinvestigates the boundary influences ofa single job resource butalsoanalyzes thecombinedefects of work relevance and moral leadership.This demonstrates how leadership styles and job design can be integrated to optimize work outcomes and provides atheoretical foundationforsubsequent research toconsider thecomprehensiveeffectsof various job resources.
