(2024) Vertical-horizontal actor collaboration in governance network: a systematic review. Public Organization Review, Volume 24, Issue 4, December 2024, pp. 1233-12521566-7170https://doi.org/10.1007/s11115-024-00794-whttps://dspace.lib.cranfield.ac.uk/handle/1826/23659This research proposes a categorization framework to analyse multi-actor collaboration variations in governance network. It examines both vertical (government levels) and horizontal (sectors) interactions. This study reviewed 92 academic articles, adhering to the PRISMA methodology and utilizes 2 × 2 and "who-how-what" frameworks to capture the breadth of vertical-horizontal collaboration arrangements. The study identifies a rise in multi-actor collaborations and a dominance of qualitative research. It exposes research gaps: limited cross-sectoral and international actor studies, and under-researched sectors beyond environment. The proposed framework, capturing actors, levers, purposes, and context, aims to guide future research on vertical-horizontal actor collaboration in governance network.pp. 1233-1252enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Governance networkPRISMA methodologySystematic reviewVertical-horizontal actor collaboration4407 Policy and Administration44 Human SocietyPolitical Science & Public Administration3505 Human resources and industrial relations3507 Strategy, management and organisational behaviourArticle1573-7098554898244
