The evidence about how entrepreneurial orientation （EO） affects firms＇ performance remains inconclusive. This study joins the research by incorporating organizational learning （OL） as a micro-macro link and by extending empirical work to the largely underexplored context of Chinese high-tech industries. Results from a survey of 252 Chinese high-tech firms demonstrate： （1） entrepreneurial orientation is positively related to firm performance; （2） organizational learning is also positively related to firm performance; （3） organizational learning partly mediates the positive impact of entrepreneurial orientation on firm performance; and （4） high-tech companies in the start-up and growth stage are likely to demonstrate stronger linkages in the EO-OL-performance relationship than in mature stage, which shows that the EO-OL-performance relationship is moderated by firms＇ life cycle.
