Abstract: Divided resource identification and acquisition behavior into in-bound and boundary-spanning resource identification and acquisition, the paper describes the influencing micro-mechanism of resource identification and acquisition behavior on technological distinctive competencies. Using the sample of 165 high-tech enterprises, an empirical research on the relationship between resource identification and acquisition behavior and technological distinctive competencies has been done, and the moderating effect of innovation orientation and assimilation competencies has been examined. The results show that both in-bound resource and boundary-spanning resource identification and acquisition has a significant impact on technological distinctive competencies. Exploitative innovation orientation positively moderates the relationship between in-bound resource identification and acquisition and technological distinctive competencies, but no obvious moderating effect on the relationship between boundary-spanning resource identification and acquisition and technological distinctive competencies. Explorative innovation orientation positively moderates the relationship between boundary-spanning resource identification and acquisition and technological distinctive competencies, but no obvious moderating effect on the relationship between in-bound resource identification and acquisition and technological distinctive competencies. Assimilation competencies positively moderates the relationship between in-bound and boundary-spanning resource identification and acquisition and technological distinctive competencies. The conclusions provide a more reasonable explanation framework for why resource identification and acquisition behavior can promote technological distinctive competencies. Furthermore, the conclusions enrich and develop resource integration theory and provide a new path of technological distinctive competencies of high-tech enterprises.
