，提高其独立性和有效性。However,thisstudyalsofoundthattheroleofindependentdirectorsisnotentirelyindependentandeffective.Inreality,independentdirectorsmaybeaffectedbyinternalcontrol,informationasymmetry,andotherfactors,whichmaypreventthemfromfullyexertingtheirrole.Therefore,inordertobetterplaytheroleofindependentdirectors,itisnecessarytofurtherimproverelevantsystemsandmechanisms,enhancetheirindependenceandeffectiveness.本研究认为独立董事在提升企业绩效方面发挥了积极的作用。然而，为了更好地发挥独立董事的作用，需要进一步完善公司治理结构和机制，提高其独立性和有效性。未来的研究可以进一步探讨独立董事的选聘机制、激励机制等问题，为企业治理和绩效提升提供更加全面和深入的指导。Thisstudysuggeststhatindependentdirectorshaveplayedapositiveroleinimprovingcorporateperformance.However,inordertobetterleveragetheroleofindependentdirectors,itisnecessarytofurtherimprovethecorporategovernancestructureandmechanisms,enhancetheirindependenceandeffectiveness.Futureresearchcanfurtherexploretheselectionandincentivemechanismsofindependentdirectors,providingmorecomprehensiveandin-depthguidanceforcorporategovernanceandperformanceimprovement.八、附录Appendix委托—代理嵌入模型是一个多层次、多维度的理论体系，旨在解析独立董事如何通过其特有的角色和职能，影响并提升企业绩效。该模型主要包括四个层次：股东与董事会之间的委托代理关系、董事会与独立董事之间的委托代理关系、独立董事与管理层之间的委托代理关系，以及独立董事与利益相关者之间的委托代理关系。Theprincipal-agentembeddingmodelisamulti-levelandmultidimensionaltheoreticalsystemaimedatanalyzinghowindependentdirectorsinfluenceandimprovecorporateperformancethroughtheiruniquerolesandfunctions.Thismodelmainlyincludesfourlevels:theagencyrelationshipbetweenshareholdersandtheboardofdirectors,theagencyrelationshipbetweentheboardofdirectorsandindependentdirectors,theagencyrelationshipbetweenindependentdirectorsandmanagement,andtheagencyrelationshipbetweenindependentdirectorsandstakeholders.独立董事在公司治理中扮演着关键角色，他们不仅代表着股东的利益，还负责监督公司的运营和管理。独立董事的职能包括但不限于：参与重大决策、审查财务报告、推荐外部审计机构、监督内部控制等。同时，独立董事也享有一定的权力，如提案权、投票权、调查权等。Independentdirectorsplayacrucialroleincorporategovernance,representingnotonlytheinterestsofshareholdersbutalsooverseeingtheoperationandmanagementofthecompany.Thefunctionsofindependentdirectorsincludebutarenotlimitedto:participatinginmajordecision-making,reviewingfinancialreports,recommendingexternalauditinstitutions,andsupervisinginternalcontrols.Atthesametime,independentdirectorsalsohavecertainpowers,suchasproposalrights,votingrights,investigationrights,etc.企业绩效评价是衡量企业运营效果的重要手段，常用的评价指标包括财务指标（如利润率、资产周转率等）、市场指标（如市场份额、客户满意度等）以及运营指标（如生产效率、质量控制等）。这些指标共同构成了企业绩效评价体系，为独立董事评估企业绩效提供了依据。Enterpriseperformanceevaluationisanimportantmeansofmeasuringtheoperationaleffectivenessofenterprises.Commonevaluationindicatorsincludefinancialindicators(suchasprofitmargin,assetturnover,etc.),marketindicators(suchasmarketshare,customersatisfaction,etc.),andoperationalindicators(suchasproductionefficiency,qualitycontrol,etc.).Theseindicatorstogetherconstitutetheperformanceevaluationsystemoftheenterprise,providingabasisforindependentdirectorstoevaluatetheperformanceoftheenterprise.近年来，越来越多的学者开始关注独立董事与企业绩效之间的关系。通过收集和分析大量数据，他们发现独立董事的存在和活跃度与企业绩效之间存在正相关关系。这一发现为独立董事提升企业绩效的机理提供了实证支持。Inrecentyears,moreandmorescholarshavebeguntopayattentiontotherelationshipbetweenindependentdirectorsandcorporateperformance.Bycollectingandanalyzingalargeamountofdata,theyfoundapositivecorrelationbetweenthepresenceandactivityofindependentdirectorsandcorporateperformance.Thisdiscoveryprovidesempiricalsupportfor
