How constraints and knowledge impact open innovation
研究了企业资源约束和外部知识丰富度如何影响其搜索策略（广度与深度）及创新绩效，基于瑞士企业调查发现约束降低绩效但拓宽搜索，外部知识与搜索呈U型关系。
Laursen and S alter (2006) examined the impact of a firm's search strategy for external knowledge on innovative performance. Based on organizational learning and open innovation literature, we extend the model hypothesizing that the search strategy itself is impacted by firm context. That is, both ‘constraints on the application of firm resources’ and the ‘abundance of external knowledge’ have a direct impact on innovative performance and a firm's search strategy in terms of breadth and depth. Based on a survey of Swiss‐based firms, we find that constraints decrease and external knowledge increases innovative performance. Although constraints lead to a broader but shallower search, external knowledge is associated with the breadth and the depth of the search in a U ‐shaped relationship .
