With the tides of new entrants constantly driving the extension of an industrial technology trajectory, how does the new entrants' divergent technological backgrounds impact their cross-industry innovation performances? To answer this question, we investigated the new entrants' pre-entry technological background, including their accumulated technology (T1) different from that of their targeted industry of entry (mobile phone industry) as well as degree of the technology difference (TD), and examined their impacts on the new entrants' cross-industry innovation performance. The empirical results confirmed a positive role of the T1, and a curvilinear impact of the TD on the firms' cross-industry innovation performance after their official entry. However, those effects gradually turn to be either weaker or insignificant. Instead, the obvious impact of the new entrants' technology accumulation pertinent to mobile phone industry (T2) after the entry is positively moderated by the TD, whereas the T1's impact on cross-industry innovation performance is negatively moderated by the TD. We discussed the theoretical and practical implications of these empirical findings at the end of this study.

随着新进入者的潮流不断推动工业技术轨迹的扩展，新进入者的不同技术背景如何影响他们的跨行业创新绩效？为了回答这个问题，我们调查了新进入者的进入前技术背景，包括他们与目标进入行业（手机行业）不同的累计技术（T1）以及技术差异程度（TD），并考察了它们对新进入者跨行业创新绩效的影响。实证结果证实了T1的积极作用，以及TD对企业正式进入后跨行业创新绩效的曲线影响。但是，这些影响逐渐变得微弱或微不足道。代替，TD对进入市场后进入手机行业（T2）的新进入者技术积累的明显影响受到TD的积极影响，而T1对跨行业创新绩效的影响却受到TD的负面影响。在本研究的最后，我们讨论了这些经验发现的理论和实践意义。
