Prior research has not indicated the influence of network structure by which distance between partners on its innovative performance. This study collects 54 Semiconductor IP Design firms for 10 years as a sample. We find that (1)The firm's innovative performance is U shaped function of the technological distance between alliance partners; (2)The more direct ties distance between alliances partners in a firm, the less the firm's innovative performance; (3)The more structural holes distance between alliance partners that a firm, the greater the firm's innovative performance. These results correspond to the previous study (Ahuja, 2000), and meet some arguments (Nooteboom et al., 2007; Gilsing et al., 2008).
