Abstract：
Compared with incremental innovation, breakthrough innovation is essential to sustaining competitive advantage, but breakthrough innovation has the characteristics of high standards and strict requirements. As the main body and foundation of enterprises, the attitude and behavior of employees play a vital role in enterprise innovation. Based on the positive organizational behavior theory and knowledge management theory, the purpose of this paper is to investigate the relationship between psychological capital and breakthrough innovation, and we also integrate tacit knowledge sharing and task interdependence into the research framework, so as to further explore the influence mechanism of employees\' psychological capital on breakthrough innovation. Utilizing a quantitative method, this study takes employees of Yunnan coffee enterprises as investigation objects, the data was analyzed using regression analysis through SPSS 24.0, and the existence of mediation was further verified by Bootstrap test. The results showed that the psychological capital of employees have a positive impact on breakthrough innovation; tacit knowledge sharing partially mediates the relationship between psychological capital and breakthrough innovation; and task interdependence plays a moderating role, that is, the stronger the task interdependence, the stronger the influence of employee psychological capital on breakthrough innovation. This study enriches the research on the influencing factors of breakthrough innovation of Yunnan coffee industry, expands the application scenarios of the related theory, emphasizes that the importance of psychological capital and the breakthrough innovation is the result of the interaction and value-added linkage of various internal and external resources.
摘要：
与增量创新相比，突破性创新对于保持竞争优势至关重要，但突破性创新具有高标准、严要求的特点。作为企业的主体和基础,员工的态度和行为对企业创新起着至关重要的作用。基于积极的组织行为理论和知识管理理论,本文的目的是研究心理资本与突破性创新之间的关系，我们还将隐性知识共享和任务相互依存纳入研究框架，从而进一步探索员工心理资本对突破性创新的影响机制。利用定量方法，本研究以云南咖啡企业员工为调查对象,通过SPSS24.0对数据进行回归分析,并通过Bootstrap检验进一步验证中介的存在.研究结果表明:员工心理资本对突破性创新有正向影响;隐性知识共享部分中介心理资本与突破性创新的关系;任务相互依赖起调节作用。也就是说,任务的相互依存性越强，员工心理资本对突破性创新的影响越强。本研究丰富了云南咖啡产业突破性创新影响因素的研究,拓展了相关理论的应用场景,强调心理资本的重要性和突破性创新是各种内外部资源相互作用和增值联动的结果。
