Abstract: Based on the sample of sourcing Cross-border Acquisitions by Chinese enterprises from Zephy database during 2000-2016 , we theoretically and empirically examine the configurations of the influence factors of the sourcing Cross-border Acquisition performance.Results suggest that, first,although institutional distance and technical capability are both important influence factors of of the sourcing Cross-border Acquisition performance,but technical ability is more important and necessary;Second,we summarizes three effective reverse learning mode in sourcing cross-border M&A by qualitative comparative analysis,that is after exploratory learning,after exploitation learning and after exploitation-exploratory learning.Third, the formal institutional distance and R&d spending after mergers and acquisitions are alternative.When the formal institutional distance is too big, it will inhibit R&D investment after the merger. Our study is helpful to improve the reverse learning theory of Emerging Market Countries,besides,it can Guide enterprises in the complex situation in sourcing cross-border M&A practice.
