中文摘要：

利用我国长三角地区、珠三角地区和环渤海地区三大经济圈的124家高新技术企业的调研数据，实证分析了模块化设计对不同层次的产品创新（包括架构创新和模块创新）的影响，并探讨了组织学习和关系网络对该影响的调节效应。研究结果显示：模块化设计对产品模块创新和产品架构创新均具有显著影响；探索性学习越深入，模块化对产品模块创新和架构创新的影响越大、越显著；开发性学习也对产品模块创新和架构创新具有调节效应，但其影响程度明显低于探索性创新；关系网络对产品模块创新具有显著的调节作用，而对产品架构创新不具有调节效应。

英文摘要：

Using the data from the investigation in 124 China＇s high-tech firms in three economic circles,this paper empirically studies the im- pact of modularity on different levels of product innovation（architectural innovation and module innovation）, and analyzes the moderating effects of organizational learning and relational network. The result shows as follows：modularity is positively related to both module innovation and architectural innovation;exploratory learning moderates the correlation between modularity and module innovation and that between modularity and architectural innovation;the effect of exploitative learning on module innovation is weaker than that of exploratory learning, although its moderating effect has been proved to be positive; relational network shows a positive moderating effect on the relationship between modularity and module innovation,but has no moderating effects on architectural innovation.
