基于2001-2012年中国上市公司技术型海外并购样本数据，本文运用事件研究法和多元回归模型实证检验海外并购中资源互补性对并购方技术创新的作用机制与结果，考察海外子公司自主权的调节机制，研究结果表明，海外并购中，资源互补性正向影响并购方技术创新；海外子公司自主权正向调节资源互补性与并购方技术创新的关系。进一步考察中国综合竞争优势的二次调节机制，发现利用中国市场规模优势增强子公司自主权的调节作用，且在国有控股子样本中更为显著，而寻求海外技术优势削弱了自主权的调节作用；传统制造和非国有企业寻求海外品牌优势增强了自主权的调节作用。本文的研究结论突破了基于传统发达国家所有权优势的研究范式，提出了不同类型企业利用母国综合竞争优势的技术创新兑现机制，为企业通过精准并购，优化海外互补性资源的整合，实现跨越式创新发展提供了理论依据。

Using a sample of technological cross-border M&As of Chinese listed firms，and the method of event-study and multiple regression model, this paper empirically tests the relationship between complementary resource and innovation performance of acquiring firm and the moderate effect of target autonomy. It is found that complementary resource has a positive relationship with technology innovation; target autonomy plays a positive moderating role. We further examine the mechanism of Chinese comprehensive competitive advantage and found that the use of market scale advantage strengthens the moderating role while the effect is more significant in state-owned enterprises; Seeking overseas technological advantage weakens the moderating role; Seeking overseas brand advantages by manufacturing and private enterprises strengthens the moderating role. The conclusion breaks through the ownership advantages of established theories. It provides a theoretical basis for Chinese firms to improve innovation by choosing appropriate cross-border M&A, optimizing the integration of complementary resources and using Chinese competitive advantage.
