Abstract
Mountain regions present unique challenges for supply chain management due to geographical, topographical, and spatial factors. These challenges make companies in these regions particularly susceptible to supply chain disruptions. This study aims to understand how companies' location influences supply chain structure, which is critical for resilience and the ability to adapt to and recover from disruptions. In this regard, the study addresses the following research question: How do companies in mountain regions structure their supply chains compared to those in non-mountain areas? To answer the research question, we use secondary data from the FactSet platform to analyze firm profiles and supply networks, with mountain firms identified via GPS coordinates and the GMBA V2.0 mountain map, and non-mountain firms through nearest-neighbor propensity score matching. Ordinary least squares regression is used to assess the impact of location on supply chain structure. The analyses are still in progress, but we expected that companies in mountain regions will exhibit narrower and less fragmented networks with fewer supply chain partners. Sectoral differences may also influence variations in supply chain structures. The research results can provide relevant contributions for theory, practice and policymaking.
