Chile is a major exporter of aquatic products. Chile's exports of aquatic products continue to rise. In order to study the main influencing factors of its export growth, we used the trade gravity model and introduced importing country's APEC membership and colony relations as two dummy variables. Chile's aquatic products exports to the top 25 markets between 2001 and 2018 were examined. The export data of aquatic products come from the trade map website, the GDP and GDP per capita data of each country come from the World Development Index database of the World Bank, and the distance data between the two countries come from the CEPII database. Chile's economic size and per capita income have no effect on its exports of aquatic products; the economic size of importing countries, APEC membership, and colonial relations have a positive impact on Chile's aquatic product exports; the economic distance between the two countries and the income level of importing countries have a negative impact on Chile's aquatic products exports.
