Evolving appropriability – Variation in the relevance of appropriability mechanisms across industries
利用三波社区创新调查数据，研究了不同行业和时间中可占有性机制使用动态，发现机制使用增加且偏好转向非正式类型，行业间存在差异，领先时间和复杂性在某些行业不可替代。
Although innovation appropriability has been studied for decades, industry-level variations and development patterns have rarely been the focus of research. Using three waves of Community Innovation Survey data, this paper empirically explores the dynamics in the use of appropriability mechanisms across time and industries. The use of appropriability mechanisms has increased, and preferences have shifted from the moderate use of formal and informal appropriability mechanisms to informal types. In addition, while there are industry differences, generally after a decade, the connections between the mechanisms are more numerous and encompass different forms. Furthermore, a necessary condition analysis (NCA) reveals differences between industries on the necessity of varying appropriability mechanisms for innovation cooperation. While ineffectiveness of intellectual property rights (IPRs) and secrecy can be compensated with other appropriability mechanisms in practically any industry, there are industries where lead time and complexity are determinants of innovation cooperation and cannot be substituted or compensated for. These insights into industry-specific patterns unveil innovation appropriability in various contexts and assist managers in resisting the dominant logics in their industry when pursuing appropriation in collaborative and converging environments.
