Drawing upon the extended resource‐based view, we examine the moderating effects of resource synchronization on the performance implications of the speed at which international new ventures (INVs) internationalize into emerging economies (EEs) versus developed economies (DEs). Using a sample of INVs from China, we discover that both speeds of internationalization into EEs and into DEs positively affect international performance, but the speed of internationalization into DEs has a greater influence. We also find that although resource synchronization positively moderates the relationships between the two speeds and international performance, it has a greater moderating role in the link between the speed of internationalization into DEs and international performance. Our findings not only contribute to the INV approach by addressing the inconsistencies about the internationalization speed and performance relationship, but also advance the resource‐based view by offering a more complete understanding of resource‐based performance advantages.
