This study develops a theoretical model integrating new public management (NPM) principles, technology acceptance factors, and collaborative governance to explain the emergence of sustainable digital insurance ecosystems powered by open data. Using structural equation modeling with data from 368 professionals (121 regulatory stakeholders, 178 industry professionals, and 69 technology enablers), we investigated how NPM principles and technology adoption factors influence behavioral intention, use behavior, and principled participation in open data initiatives. The results revealed dual pathways to sustainable outcomes: technological adoption (β = 0.27) and collaborative governance through open data sharing, with principled engagement demonstrating stronger influence (β = 0.45). Performance expectancy emerged as the strongest predictor of behavioral intention, while accountability and market-driven services significantly enhanced stakeholder engagement in open data platforms. Multigroup analysis showed differential effects across stakeholder categories, with regulatory stakeholders less influenced by efficiency considerations but more likely to translate technology use into collaborative engagement. This study contributes to public administration theory by demonstrating complementarities between NPM and collaborative governance in open data contexts, extends technology adoption frameworks to regulatory technology contexts, and provides evidence-based guidance for developing balanced digital regulatory approaches. The stronger influence of principled engagement on sustainable outcomes suggests that collaborative governance mechanisms are particularly critical for sustainability, challenging technocentric perspectives that prioritize digital tools over relational dimensions of regulatory governance in open data initiatives. By illuminating the complex interplay between managerial principles, technological factors, and collaborative mechanisms in open data ecosystems, this research offers a comprehensive framework to navigate the digital transformation in insurance regulation.
