Regional resilience during COVID-19: evidence from Colombian exporting clusters
研究利用二分网络分析和社区检测方法识别哥伦比亚各省的出口集群，考察集群是否提升企业贸易边际，发现集群并非自动改善贸易表现，且危机中企业反应存在差异，为理解出口集聚如何影响区域韧性提供证据。
This study characterises the geography of Colombian exporters and their response to the COVID-19 crisis. We define exporting clusters within departments using bipartite network analysis and community detection tools. The methodology empirically detects product communities – groups of products that are strongly related – which are compared with an alternative taxonomy of industrial clusters, and clusters exporting firms by considering their exports within these taxonomies. We define these groups of specialised firms localised in departments as exporting clusters. We then examine whether belonging to an exporting cluster can enhance firms’ trade margins. We find that clusters do not automatically improve firms’ trade margins and that there are differences in how firms react to a crisis within clusters. Our analysis contributes to regional studies by shedding light on the potential of exporters’ agglomerations to navigate and recover from crises and outlining critical firm characteristics that can strengthen regional resilience.
