In this study, we tested influences of a group's intra-knowledge transfer capability as a mediator and ties strength as a moderator of knowledge sharing through an inter-alliance network. Diffusion of innovation occurs more among Chinese authors who live in China than among Chinese authors living in the US. One of the limitations of this study is that the quantitative **data** used lacks information about the authors' demographic **data** such as age and gender. Future studies could focus more on the inter-organizational learning process and resources. In addition, further research could be focused on testing the moderation effect of diverse authors' perspectives in a group and see if the relationship between intra-network learning and intra-network knowledge transfer capability is moderated by the diversity between the authors' perspectives or research areas. Follow-up studies could consider cross-sectional data, more countries, more research areas (the macro level), and different network structures (see Figure 1).
