中文摘要：

以公司治理困境为切入点，讨论如何配置公司股权结构既能发挥股东的支持行为，又能增强经理人的主动性，最终促进企业自主创新行为。整合代理理论与行为动机理论，引入经理人创新动力作为中介变量，并将市场竞争程度和创新空间作为调节变量加入模型，探讨股权集中度对自主创新行为的作用路径，利用182家企业的调研数据进行模型检验。研究结果表明，股权集中度与经理人创新动力、自主创新行为之间都存在倒U形关系，股权集中度通过经理人创新动力间接影响自主创新行为，创新空间正向调节经理人创新动力与自主创新行为间的关系，且这一调节效应不影响经理人创新动力中介作用的发挥，市场竞争程度的调节作用并不显著。

Extant study exploring how corporate governance influences innovation mainly focuses on the perspective of owners ormanagers in an agent relationship, which may yield governance dilemma paid inadequate attention to previously .Thus, there existsa necessity to explore how to configure corporate ownership structure to stimulate owner ′s incentive effect as well as enhancemanager′s initiative so as to further facilitate corporation indigenous innovation behavior .Accordingly, it is deserved in-depth analysisof the internal influence mechanism of ownership concentration regarding managers as the breakthrough point .Inspired bythe aforementioned discussions, integrating agency theory, behavior-motivation theory, and innovation theory, this paper introducesmanager′s innovation motivation as mediating variable to link ownership concentration and corporation indigenous innova -tion behavior.Meanwhile, as it is held better to match inside enterprise environmental factors with the outside ones , this studyfurther introduces market competition and innovation space to analyze the moderated effect in the relationship of manager ′s innovationmotivation and corporation indigenous innovation behavior .Subsequently, using the data from 182 samples of companies in China, we adopt hierarchical regression analysis to examinethese relationships.Our findings indicate that： ①there is an inverted-U shape relationship between ownership concentration andmanager′s innovation motivation, corporation indigenous innovation behavior .②manager′s innovation motivation mediates theeffect of ownership concentration on corporation indigenous innovation behavior .③innovation space strengthens the positive effectof manager′s innovation motivation on corporation indigenous innovation behavior , while the moderation effect of market competi -tion is insignificant.Specifically, the mediation effect of manager′s innovation motivation has its robustness against the modera -tion effect of innovation space.Our study contributes to pr
