Understanding the effects of different sources of knowledge acquisition in public organizations has become widely promoted for overcoming sociotechnical challenges through innovation. This study divided the sources of knowledge into external and internal learning mechanisms to assess their divergent effects on incremental and transformative innovations in 82 local governments involved in green and blue infrastructure projects. First, the study tests whether more diverse external sources of knowledge acquisition are more effective in increasing transformative innovation than internal learning mechanisms. The second proposition tests whether internal changes in organizational routines are associated with incremental rather than transformative innovation. Results from mediation analysis using structural equation models confirm that the initial negative effect of external and internal learning mechanisms on innovation can be eliminated, on the one hand, by engaging in more diverse cross-sector collaborations to increase transformative innovations and, on the other hand, by focusing on changing administrative routines to support incremental innovation.

公共部门创新性质的知识来源动态：了解地方政府的增量和变革性创新

了解公共组织中不同知识获取来源的影响已得到广泛推广，以通过创新克服社会技术挑战。本研究将知识来源分为外部和内部学习机制，以评估它们对参与绿色和蓝色基础设施项目的 82 个地方政府的增量和变革性创新的不同影响。首先，该研究检验了更多样化的外部知识获取来源是否比内部学习机制更有效地增加变革性创新。第二个命题测试组织惯例的内部变化是否与渐进式而非变革性创新相关。
