While citizen participation in policymaking is on the rise worldwide, the scholarly debate centring around its evaluation has not developed to the same extent. The article discusses the methodology and findings of the evaluation of the project “Portugal Participa: Caminhos para a Inovação Societal” which started at the end of 2014, and was implemented in 2015 and 2016, in Portugal. As the project promoted actions at both national and local levels, the evaluation accounted for both layers with a major focus on the analysis of procedures and outputs to examine its success. Through the application of a multi-method approach – data collection and analysis, cost-effectiveness assessment, interviews, pre-post surveys, and counterfactual focus groups – involving a wide array of agents – political representatives, civil servants, NGOs, citizens, national academia, and the funding sponsor – findings have helped retrieve three main insights that aim to contribute to future research on the evaluation of citizen participation in policymaking, which should shed light on: the (re)connection of multiple agents; the role within the governance systems; and the pursuit of social inclusion.

虽然全球范围内的公民参与决策的人数正在增加，但围绕其评估的学术辩论并没有发展到同样的程度。本文讨论了对“葡萄牙参与：Caminhos para a Inovação Societal”项目的评估方法和结果，该项目于 2014 年底开始，并于 2015 和 2016 年在葡萄牙实施。由于该项目促进了国家和地方层面的行动，因此评估考虑了两个层面，主要关注程序和产出的分析，以检验其成功与否。通过应用多种方法——数据收集和分析、成本效益评估、访谈、事前调查和反事实焦点小组——涉及广泛的代理人——政治代表、公务员、非政府组织、公民、国家学术界和资助者——调查结果帮助检索了三个主要见解，这些见解旨在为未来关于公民参与决策评估的研究做出贡献，这应该阐明： 多个代理的（重新）连接；在治理系统中的作用；以及对社会包容的追求。
