The recent narrative on museums as catalysts of innovation and growth considers their relations with other cultural and creative industries (CCIs) to be very important. We argue that most relations museums establish with CCI firms and institutions are unlikely to produce strong positive externalities that make the latter more innovative. To prove this claim, we propose a conceptual framework qualifying project-based and supply chain relations between museums and CCIs as either strong, moderate, or weak links, according to their potential in terms of knowledge spillovers from museums to CCIs. We apply this taxonomy to data collected from 261 Polish museums. Our findings indicate that strong links are outnumbered by moderate and weak ones. We then suggest that the traditional missions of museums, in particular education and conservation, need to be more thoroughly assessed in terms of their direct and indirect contributions in order to fully capture the impact of museums on innovation in the wider economy.

最近关于博物馆作为创新和增长催化剂的叙述认为，博物馆与其他文化和创意产业（CCI）的关系非常重要。我们认为，博物馆与CCI公司和机构建立的大多数关系不太可能产生强大的积极外部性，从而使后者更具创新性。为了证明这一主张，我们提出了一个概念框架，根据博物馆与CCI之间的知识溢出潜力，将博物馆与CCI之间基于项目和供应链的关系限定为强，中或弱链接。我们将此分类法应用于从261个波兰博物馆收集的数据。我们的研究结果表明，中度和较弱的联系数量多于牢固的联系。然后，我们建议博物馆的传统任务，特别是教育和保护，
