中文摘要：	随着企业全球化竞争的加剧，社会生产中高科技产品的比重不断上升，技术创新成为企业增强其核心竞争力的重要战略。目前企业一般通过两种方式提升自身的技术创造能力，一是通过传统的内部研发，企业在已有的人力资源与技术知识的基础进行自主研究开发，即内部R&D；另一种是对外寻求技术购买的方式，如通过兼并与收购等获取知识和技术成果从而提升自身的创新实力，即外部R&D。本文主要研究并购后，内部R&D与外部R&D两种方式如何影响企业的创新绩效。 企业内部自主研发主要依靠企业内部的研究团队与技术资源，独立地进行技术研究开发及其他创新活动，为企业积累技术信息和科技研发能力；最常见的外部R&D方式即为寻求外部技术并购，通过直接购买被并公司的股权或者专有技术成果，可以避免内部研发周期长、风险大的弊端。在目前的研究里，学者们对内部自主研发与技术购买之间的关系有不同的见解。因此，本文重点研究两种方式对并购后企业创新能力的影响是替代关系还是协同关系。此外，本文还探讨了主并企业与被并企业的相对技术差异，从技术方向与技术规模差异两个角度探讨其对企业创新成果影响的调节作用。 本文选用2013-2016年高新技术行业的沪深上市公司的472起并购事件作为研究样本，以实证的方法研究内外部R&D对企业创新绩效的交互作用，并对相对技术差异起到的调节作用进行验证。结果表明：主并方已有的内部自主研发基础正向影响并购后企业的创新产出，主并方实施技术并购也有利于提升并购后的创新绩效；已有的自主研发基础与技术并购对提升企业创新绩效起到了协同作用；相对技术差异对内外部R&D之间的协同效应具有调节作用。当主并公司与目标公司处于同一技术方向时会对协同作用产生正的调节作用，而技术规模差异会对协同效应产生负向的调节作用。 本文的贡献是将自主研发、技术并购与相对技术差异放置于一个框架中探究主并企业创新绩效，拓展了创新成果的影响机制以及并购后创新绩效的影响路径的研究。
英文摘要：	With the trend of economic globalization, the proportion of high-tech products in social production is rising steadily, and technological innovation has become an important strategy for enterprises to enhance their core competitiveness. At present, enterprises generally improve their technological creativity in two ways: first, through traditional internal research and development, enterprises conduct independent research and development on the basis of existing human resources and technical knowledge, that is, internal R&D; The other way is to seek for external technology purchase, and acquire knowledge and technological achievements through mergers and acquisitions, so as to improve their own innovation strength, namely external R&D. This dissertation mainly studies how internal R&D and external R&D affect the innovation performance of enterprises after merger and acquisition. The independent research and development within the enterprise mainly relies on the internal research and development strength of the enterprise, independently carries out the research and development and innovation activities of the technology, and accumulates the technology information technology research and development capability for the enterprise; The most common way of external R&D is to seek for technology mergers and acquisitions. Through direct purchase of equity or proprietary technology achievements of the merged company, the disadvantages of long internal R&D cycle and high risks can be avoided. In the current study, scholars have different views on the relationship between internal independent research and development and external technology purchase, two ways to improve the innovation ability of enterprises. Therefore, this dissertation focuses on the research of the two ways of the impact on the innovation ability of enterprises after mergers and acquisitions is the substitution relationship or the collaborative relationship. In addition, this dissertation also discusses the relative technological differences between the two sides of the merger and acquisition transaction, that is to say, the moderating effect of the differences in technological direction and technological scale on the innovation achievements of enterprises. In this dissertation, 472 mergers and acquisitions of a-share listed companies in the high-tech industry from 2013 to 2016 were selected as the research samples. Based on the existing theories of scholars, the hypothesis was proposed and the corresponding model was established to study the interaction between internal and external R&D on enterprise innovation performance by empirical method, and the regulating effect of relative technological differences was discussed. The results show that: 1. The existing internal independent research and development foundation of the merging party positively affects the innovation output of the enterprise after the merger, and the technology merger is also conducive to the improvement of the innovation performance after the merger. 2. The existing independent research and development foundation and technology mergers and acquisitions play a synergistic role in improving the innovation performance of enterprises; 3. Relative technical differences have a moderating effect on the synergies between internal and external R&D. When the main merger company and the target company are in the same technological direction, they will have a positive regulating effect on the synergy. Meanwhile, the difference in relative technological scale will have a negative regulating effect on the synergy. At present, there is a lack of literature on the independent research and development, technology merger and acquisition and relative technology difference in a framework to explore the innovation performance of co-ownership enterprises. Therefore, the research on this topic can further study the impact mechanism of innovation results and the impact path of innovation performance after merger and acquisition.
