摘 要:本文利用2007—2017年中国上市企业国际化研发及专利引用数据,采用双重差分法探究后发企业研发国际化对企业创新价值获取的作用机制及效果。研究结果表明:国际化研发对企业创新价值获取产生了重要影响,但在国内外的作用机制及影响效果存在较大差异;研发国际化通过延长专利国内首次被引时间间隔、降低专利国内引用次数,对企业国内创新价值获取呈现出独占效应;研发国际化通过缩短专利国外首次被引时间间隔、提升专利国外引用次数,对企业国外创新价值获取呈现出共享效应;研发国际化显著提升了企业专利知识的宽度及深度,专利知识宽度作为异质性知识组合隔离效果的体现有助于国内独占效应的形成;专利知识深度作为企业创新质量提升赶超效果的表现有助于国外共享效应的形成。Based on the data of R&D internationalization and patent citation of Chinese listed companies from 2007 to 2017,this paper explores the effect of R&D internationalization of latecomer firms on their innovation value acquisition and the mechanism of action using the DID method.The results show that R&D internationalization has an important impact on enterprises’ innovation value acquisition,but its mechanism and effect are quite different at home and abroad.On the one hand,R&D internationalization has an“exclusive”effect on enterprises’ domestic innovation value acquisition by extending the time interval of the first domestic patent citation and reducing the frequency of domestic patent citation.On the other hand,R&D internationalization presents a “sharing”effect on enterprises’ overseas innovation value acquisition by shortening the time interval of the first overseas patent citation and increasing the frequency of overseas patent citation.R&D internationalization significantly increases the width and depth of enterprises’ patent knowledge.Reflecting the isolation effect of heterogeneous knowledge combination,the patent knowledge width contributes to the formation of the domestic “exclusive”effect;reflecting the improving and catch-up effect of enterprises’ innovation quality,the patent knowledge depth contributes to the formation of the overseas “sharing”effect.
