Abstract：Drawing on behavior strategy theory, this study aims to examine the relationship among role commitment, cross-sector knowledge sharing and technological innovation performance. Results of an experience-sampling study of 239 firms show that there exists “inverted U” relationship between role commitment and cross-sector knowledge sharing, and cross-sector knowledge sharing has a direct positive effect on firm technological innovation performance. There exists “inverted U” relationship between role commitment and firm technological innovation performance either, and cross-sector knowledge sharing plays a intermediary role between role commitment and firm technological innovation performance.
