International Trade Data (HS, 22)

The Atlas of Economic Complexity maintains trade data in multiple international classification systems. This data set contains trade flows classified via Harmonized System (HS) 2022. HS data offers a contemporary and detailed classification of goods, but covers a relatively short time period: Categorizes approximately 5,600 goods Coverages starts in 2022 Categories break down to 1-, 2-, 4-, or 6-digit detail levels (though country reporting can be less reliable at the 6-digit level) Raw data on trade in goods is provided by United Nations Statistical Division (COMTRADE). The data is then cleaned by Growth Lab researchers using the Bustos-Yildirim Method which uses bilateral trade flows to account for inconsistent reporting and provides more reliable accounting. A data dictionary for this repository describing columns within these files can be found under \"hs22_data_dictionary.csv\".经济复杂度图谱（The Atlas of Economic Complexity）维护采用多种国际分类体系的贸易数据。本数据集包含采用2022版协调制度（Harmonized System, HS）分类的贸易流量数据。 协调制度数据兼具时效性与细致分类的优势，但覆盖时长相对有限：该分类体系涵盖约5600种商品，数据起始覆盖年份为2022年，分类层级可细化至1位、2位、4位或6位编码（不过6位编码层级的国家申报数据可靠性相对较低）。 本数据集的商品贸易原始数据由联合国统计司（United Nations Statistical Division, COMTRADE）提供。随后，增长实验室（Growth Lab）的研究人员采用布斯托斯-伊尔迪里姆法（Bustos-Yildirim Method）对数据进行清洗：该方法通过双边贸易流量修正申报不一致的问题，进而提升数据核算的可靠性。 本仓库各文件的列项说明数据字典可于‘hs22_data_dictionary.csv’中查阅。
