ABSTRACT
Research objectives and hypothesis/research questions:
This study examines the complementary roles of the public and private sectors in advancing sustainability, focusing on the role of partnerships (SDG 17) in implementing the 2030 Agenda for Sustainable Development. The objectives are comparing the institutional frameworks shaping sustainability practices, analyzing how differences in governance mechanisms influence sustainability outcomes, and evaluating the contribution of public-private partnerships for SDG implementation. The study hypothesizes that, despite their distinct institutional logics, the two sectors are complementary rather than incompatible, and that partnerships, supported by strong leadership, enhance sustainability outcomes.

Research methods:
The study proposes a narrative literature review and conceptual comparative analysis, synthesizing approximately 40 academic and institutional sources published primarily between 2007 and 2026, together with foundational international policy documents, to examine institutional, managerial, and governance approaches to sustainability in the public and private sectors.

Main results:
The results show that the effectiveness of governance depends on regulatory governance, stakeholder engagement, and network cohesion, with the public sector often constrained by bureaucratic fragmentation. The paper concludes that sustainability should be understood as a collective and interdependent effort rather than the responsibility of any single sector. Achieving the SDGs depends on the capacity of public and private actors to collaborate within well-designed governance frameworks that combine leadership, innovation, legitimacy, efficiency, and equity. Strengthening partnerships, fostering cross-sector leadership, and promoting continuous learning are therefore essential for enhancing the impact of sustainability initiatives.

Implications for theory and practice:
The analysis shows that divergent institutional logic does not necessarily create incompatibility, but rather reveals significant potential for complementarity. This document highlights the complexity of institutional environments and the need for coherent frameworks that remove sectoral barriers and strengthen governance.
