中文摘要：

当前对企业选择网络中心位置还是网络中介位置进行产品创新仍存有争论，而同时引入技术战略导向和市场动态性两个调节变量分析两种网络位置对产品创新绩效的权变效应有可能破解这个难题。通过对浙江省208家制造企业的实证研究发现，两种网络位置对产品创新绩效都有正向影响，且企业技术战略导向越高，这种正向效应越显著；市场动态性越高，网络中介位置对产品绩效的正向效应越显著，但市场动态性对网络中心位置与产品创新绩效关系负向调节作用并不显著。研究结论不仅明确了不同网络位置发挥效用的具体情境，也为企业选择合适的网络位置进行产品创新提供了启示。

英文摘要：

At present, there are debates on that in order to conduct product innovation, either prominent network position or entrepreneurial network position should be selected. It is possible to settle the puzzle if two moderate variables, that is, technology oriented strategy and market dynamics, are introduced to analyze the contingent effect on innovation performance caused by these two network positions. Through the empirical study on 208 manufacturing firms in Zhejiang Province, China, it is found that these two network positions both have positive effects on product innovation performance, and the higher the firm~ technology -oriented strategy is, the more significant the positive effects will be. The higher the market dynamics is, the more significant positive effects on product innovation performance the entrepreneurial network position will have, however, the negative moderate effects of market dynamics on the relationship between prominent network position and product innovation performance is insignificant. The conclusions not only clarify the detailed context for the utility of different network position, but also provide implications on how to choose appropriate network position for conducting product innovation of firms.
