Roman Transport Network Connectivity and Economic Integration
研究发现，罗马时期首个泛欧多式联运交通网络的连通性影响了当时跨区域贸易，且这种影响延续至今，体现在企业跨区域投资行为中，部分原因在于基础设施路径选择和文化融合。
Abstract We show that the creation of the first integrated multi-modal pan-European transport network during Roman times influences economic integration over two millennia. Drawing on spatially highly disaggregated data on excavated Roman ceramics, we document that contemporary interregional trade was influenced by connectivity within the network. Today, these connectivity differentials continue to influence integration as approximated by cross-regional firm investment behaviour. Continuity is partly explained by selective infrastructure routing and cultural integration due to bilateral convergence in preferences and values. We show that our results are Roman-connectivity specific and do not reflect pre-existing patterns of exchange using pre-Roman trade data.
