论文摘要
海上运输是国际贸易的骨干，因此是世界经济。装载的船只通过底层港口运输网络从一个国家的港口到另一个国家的港口，在途中促成了国家的国际贸易价值。我们假设涉及跨职业活动的港口是第三方经纪人，可以调解两个外国之间的贸易，并为相应的国家在国际贸易领域的地位做出贡献。我们使用全球衬里运输服务的端口级数据集检验了这一假设。我们提出了两个指数，以量化国家在全球班轮运输网络中的重要性，并表明他们解释了各个国家的国际贸易价值和相关措施的大量差异。这些结果支持尚未直接测试的海洋经济学的长期观点，即强烈融入全球海上运输网络的国家可以增强进入全球市场和贸易机会的机会。
Maritime shipping is a backbone of international trade and, thus, the world economy. Cargo-loaded vessels travel from one country's port to another via an underlying port-to-port transport network, contributing to international trade values of countries en route. We hypothesize that ports that involve trans-shipment activities serve as a third-party broker to mediate trade between two foreign countries and contribute to the corresponding country's status in international trade. We test this hypothesis using a port-level dataset of global liner shipping services. We propose two indices that quantify the importance of countries in the global liner shipping network and show that they explain a large amount of variation in individual countries' international trade values and related measures. These results support a long-standing view in maritime economics, which has yet to be directly tested, that countries that are strongly integrated into the global maritime transportation network have enhanced access to global markets and trade opportunities.
