中文摘要：

目前对跨界搜索与创新之间关系的研究主要聚焦于技术知识跨界搜索，却忽视了市场知识跨界搜索的影响。本文利用270个中国制造企业调查数据，同时研究了技术知识和市场知识的跨界搜索对产品创新的影响，并探讨了两个重要情境变量一行业竞争强度和所有权类型的调节作用。实证结果表明：（1）技术知识和市场知识的跨界搜索都能促进产品创新；（2）行业竞争强度和所有权类型对上述关系存在着调节作用。随着行业竞争强度的增强，技术知识跨界搜索对产品创新的影响变大，而市场知识跨界搜索对产品创新的影响变小；相对于内资企业，外资企业进行市场知识跨界搜索对产品创新的影响较小，但是，并没有发现二者在技术知识跨界搜索与产品创新的关系有显著不同。

英文摘要：

Previous researches on the relationship between the transbeundary search and innovation focus on the transbeundary search of the technological knowledge, ignoring the effects of the transbeundary search of the market knowledge. By using an orig- inal data set of 270 manufacturing firms in China, this study aims to examine the impacts of the transboundary search of the tech- nological knowledge and the market knowledge on the product innovation during economic transitions and discusses the modulatory effects of two important situational variables, namely the industry competitive intensity and the ownership type. The results show that （ 1 ） the transboundary search of the technological knowledge and the market knowledge can both promote the product innova- tion; and （2） the industry competitive intensity and the ownership type moderate the above relationship. Specially, with the en- hancing industry competitive intensity, the impact of the transboundary search of the technological knowledge on the product inno- vation is increasing while the impact of the transboundary search of the market knowledge on the product innovation is decreasing. In comparison, the relationship between the transbeundary search of the market knowledge and the product innovation is weaker for foreign - invested firms than for domestic - invested firms. However, there is no significant difference on the relationship be- tween the transboundary search of the technological knowledge and the product innovation for them.
