企业国际化如何影响创新绩效？知识搜索的中介作用与母国市场竞争程度的调节作用

How does Internationalization Affect Innovation Performance? The Mediating Role of Knowledge Search and the Moderating Role of Degree of Home Market Competition

摘要:

新兴经济体实施国际化战略对提升企业创新绩效具有重要意义，然而现有研究对其中介机制和调节作用的探讨不足。本研究构建“国际化程度——知识搜索——创新绩效”的理论逻辑，通过以技术边界划分知识搜索为本地搜索和跨界搜索，将其作为中介因素探索新兴经济体企业的国际化程度对创新绩效的影响，并进一步探索了母国市场竞争程度对国际化程度与知识搜索之间关系的调节作用。采用中国A股制造业上市公司跨度19年的数据进行实证检验，结果表明：（1）国际化程度对创新绩效呈倒U型影响。（2）国际化程度对本地搜索和跨界搜索都有显著正向影响，本地搜索对创新绩效也有正向影响，但跨界搜索对创新绩效呈倒U型影响。（3）知识搜索在国际化程度和创新绩效之间起有效中介作用。（4）母国市场竞争程度在国际化程度和知识搜索之间起到正向调节作用。综上，由于知识搜索在国际化程度与创新绩效之间产生中介效应，本地搜索与创新绩效之间的正向线性关系，以及跨界搜索与创新绩效之间的倒U型关系，可以在一定程度上解释企业国际化程度与创新绩效之间正向线性关系或倒U型关系的来源；同时，母国市场竞争程度可以通过提升国际化程度对企业本地搜索和跨界搜索的促进作用，促进企业创新绩效的提高。

Abstract:

Implementing international strategy in EMNEs is of great significance to enhance firm’s innovation, but there is still controversy in the academic circles on whether internationalization can promote innovation.The study constructs the theoretical logic of "degree of internationalization -- knowledge search -- innovation performance", then dividing knowledge search into local search and boundary-spanning search by technology boundary and using them as mediating factors, we explore the impact of internationalization on innovation performance of firms in emerging economies, and further explores the moderating role of home country market competition in the relationship between the degree of internationalization and knowledge search. Based on the data of China's A-share manufacturing listed companies spanning 19 years, the empirical test results show that: (1) the degree of internationalization has an inverted U-shaped effect on innovation performance. (2) The degree of internationalization has a significant positive effect on both local search and boundary－spanning search. Local search also has a positive effect on innovation performance, but boundary－spanning search has an inverted U-shaped effect on innovation performance. (3) Knowledge search plays an effective mediating role between internationalization degree and innovation performance. (4) The degree of competition in the home market plays a positive moderating role between the degree of internationalization and knowledge search. In summary, the positive linear relationship between local search and innovation performance, as well as the inverted U-shaped relationship between boundary－spanning search and innovation performance, can explain the source of the positive linear relationship or inverted U-shaped relationship between internationalization degree and innovation performance to a certain extent, due to the mediating effect of knowledge search between the degree of internationalization and innovation performance. At the same time, the degree of competition in the home market can promote the local search and boundary－spanning search of enterprises by improving the degree of internationalization, and promote the improvement of enterprise innovation performance.
