国际化已成为新兴经济体国家实现创新追赶的重要战略选择。本文利用2014-2016年879家高新技术企业相关数据，针对企业多种国际化行为对创新绩效的影响进行理论分析与实证检验。并突破传统资源观和学习观，验证企业吸收能力在国际化行为与创新绩效间的中介作用及研发投入的调节作用。结果表明：1.国际化行为显著促进企业创新绩效提升，其中海外人才促进效果最强，海外出口次之，海外研发最弱。2.企业吸收能力在部分国际化行为与创新绩效间存在中介作用。3.研发投入在不同国际化行为与吸收能力间均存在调节作用，效果不同。

Internationalization has become an important strategic choice for emerging economies to catch up with innovation.This paper uses the data of 879 high-tech enterprises from 2014 to 2016 to conduct theoretical analysis and empirical tests on the effects of various internationalization behaviors on innovation performance.This study also break through traditional resources and learning concepts and validates the intermediary role of corporate absorptive capacity between internationalization behavior and innovation performance and the regulatory role of R&D investment.Research indicates:1.The internationalization behavior significantly promotes the improvement of corporate innovation performance,of which overseas talents have the strongest effect,followed by overseas exports,and overseas research and development are the weakest.2.The absorptive capacity of enterprises has an intermediary role between partial internationalization behaviors and innovation performance.3.R&D investment has a regulating effect between different internationalization behaviors and absorptive capacity, with different effects.
