The socio-environmental crisis and the complexity of urban problems highlight the importance of better understanding the emergence and configuration of social innovation ecosystems (SIEs) and their impact on cities. This article proposes a new theoretical–methodological approach that is inspired in a pragmatism perspective and presents results of its empirical application in the mapping and analysis of the SIE in the city of Florianópolis, Brazil. The study was put into practice through the creation and implementation of a collaborative digital platform that made it possible to make a cartography of the network that forms the city’s SIE, shedding light on the linkage between micro-meso-macro-scales of SIEs. The research findings contribute to raising key aspects in each scale of SIE that could foster or hinder social innovation dynamics. In this sense, besides contributing to understanding the dynamics of SIEs better, the purpose of this study was to analyze the configuration, scope, and limits of the SIE to reinforce the processes of democratic experimentation and to strengthen the sustainability of cities, especially in countries of the South, where these studies are still scarce.

社会环境危机和城市问题的复杂性凸显了更好地了解社会创新生态系统（SIE）的出现和配置及其对城市的影响的重要性。本文提出了一种新的理论方法论方法，该方法从实用主义的角度受到启发，并提出了其在巴西弗洛里亚诺波利斯市SIE的制图和分析中的经验性应用结果。通过创建和实施协作数字平台将这项研究付诸实践，该协作平台使制作城市SIE的网络制图成为可能，从而阐明了SIE的微观-宏观-宏观尺度之间的联系。研究结果有助于提高SIE各个规模中的关键方面，这些方面可能会促进或阻碍社会创新动力。
