Abstract: Based on the validated survey data from 211 export-oriented manufacturing enterprises in Yangtze River Delta region in China, this paper reveals the linkage mechanism among overseas network embeddedness, international learning and internationalization speed under the background of accelerated internationalization. The results show that firstly overseas network embeddedness has a prominently positive effect on international learning and internationalization speed, secondly, international learning has a prominently positive effect on internationalization speed. International learning plays a complete mediating effect between overseas network relational embeddedness and internationalization speed, but international learning plays a partial mediating effect between overseas network structural embeddedness and internationalization speed. This study reveals the linkage mechanism between overseas network embeddedness and internationalization speed, the results provide a theoretical and methodological contribution to the study of relationship between network embeddedness and enterprise internationalization, and can thus improve network embeddedness and international learning in practice of Chinese enterprises “going out” strategy.
