从全球班轮运输网络估算各国的国际贸易状况
Estimating international trade status of countries from global liner shipping networks
摘要：
海运是国际贸易的支柱，因而也是世界经济的支柱。装载货物的船只通过基本的港到港运输网络从一个国家的港口到另一个港口，增加了沿途国家的国际贸易价值。我们假设，涉及转运活动的港口作为第三方经纪人，调解两个外国之间的贸易，并有助于相应国家在国际贸易中的地位。我们使用全球班轮运输服务的港口级数据集来检验这一假设。我们提出了两个指数，量化国家在全球班轮运输网络中的重要性，并表明它们解释了单个国家的国际贸易值和相关措施的大量变化。这些结果支持了海洋经济学中一个长期存在的观点，该观点尚未得到直接检验，即有力地融入全球海洋运输网络的国家增加了进入全球市场和贸易机会的机会。
英文摘要：
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.
