Retrospect and Prospect of Academic Research on the Tibeto-Yi Corridor in the Past Forty Years: From “Ethnic Corridor” to “Community Space”

Background: The Tibeto-Yi Corridor, a geographically significant transition zone between the eastern Tibetan Plateau and southward ecosystems, serves as a vital historical conduit for migration, trade, and cultural exchange among diverse ethnic groups. Despite its strategic importance, the theoretical framing of the region has undergone significant shifts that require systematic synthesis. Objective & Methodology: This paper provides a comprehensive review of four decades of academic research on the Tibeto-Yi Corridor. Utilizing an interdisciplinary approach that integrates findings from anthropology, history, geography, and linguistics, the review examines the conceptual evolution of the region. The methodology focuses on tracing the transition from the "ethnic corridor" framework to the "community space" paradigm through a qualitative meta-analysis of key scholars and research trends. Key Findings: The analysis reveals a paradigm shift: early ethnographic studies (1980s–1990s) initially framed the region as an "ethnic corridor," emphasizing bounded ethnic interactions and cultural diffusion. Contemporary scholarship has since transitioned toward conceptualizing the area as a dynamic "community space," highlighting integrated socio-economic lives, overlapping identities, and cultural hybridity (H=f(x,y)). The review further identifies critical tensions between state-led development initiatives—such as infrastructure and tourism—and local ecological sustainability, where the net benefit depends on the balance between economic gains (B) and environmental/social costs (C). Conclusion & Implications: The paper concludes that addressing the corridor's complex socio-ecological challenges requires a shift toward community-based participatory research (CBPR) and the integration of indigenous ecological knowledge (IEK). By advocating for a "community space" framework, this study provides a more nuanced understanding of ethnicization and place-making, offering a theoretical foundation for inclusive development policies that respect local agency.
