Bridging the Cognitive Gap: A Public Participation Framework for Evaluating Sustainable Urban Investment

Sustainable urban investment increasingly depends on the mobilization of cross-border capital to address pressing environmental and social challenges. Yet, critical investment decisions are frequently hindered by a profound cognitive gap between external international investors and the nuanced, locally embedded sustainability opportunities available on the ground. To bridge this divide, this paper proposes an innovative public participation framework designed to convert dispersed, qualitative signals-such as community preferences, localized expert judgment, and early-stage project feasibility assessments-into highly structured, actionable market intelligence. This intelligence is specifically optimized for rigorous investment screening and strategic capital allocation. Methodologically, the study systematically synthesizes interdisciplinary literature spanning participatory governance, impact measurement, and advanced market research. It translates these theoretical principles into a robust, operational evaluation architecture composed of three integrated data channels: venture-grade project submissions, comprehensive public-facing engagement feedback, and rigorous expert panel scoring mechanisms. The empirical results indicate that these participatory signals can be systematically standardized into highly comparable quantitative indicators. This standardization significantly improves overall market transparency, substantially reduces information asymmetry between local stakeholders and foreign investors, and supports highly repeatable, data-driven decision workflows. Ultimately, the paper concludes that public participation should no longer be viewed merely as a procedural legitimacy tool. Instead, it functions as a powerful analytical instrument that meaningfully strengthens due diligence quality, enhances comparability across highly heterogeneous projects, and significantly improves the interpretability of sustainable urban investment theses for diverse cross-border stakeholders.
