Customs data refers to information collected, compiled, statistically processed, and published by national customs authorities regarding import-export goods, including their transportation, pricing, quality, origin, and other relevant aspects. This data typically reflects a nation or region's import-export trade volume, trade structure, trade partners, and related information. China's customs import-export data serves as a crucial source for understanding the import-export activities of Chinese enterprises, characterized by comprehensiveness, granularity, reliability, and customizability. It holds significant value for businesses and research institutions in formulating import-export trade strategies, conducting market analysis, and other endeavors.
CnOpenData matched the list of A-share listed companies and their subsidiaries with the "Operating Unit Name" field within China's customs import-export data, encompassing both pre-listing and during-listing periods. This process yielded detailed customs import-export transaction data for A-share listed companies. This dataset includes fields such as Security Code, Accounting Year, Relationship to Listed Company, Associated Company Name, Year, HS Product Code, Amount_USD, Quantity, Operating Unit Name, and Production/Consumption Region Name. It provides robust data support for relevant research.
