The invention provides a global ship cargo quantity statistical analysis method and system, and the method comprises the steps: employing an STDistance function to calculate the distance from a first berthing point in ship berth data to each berthing line of a plurality of berths based on the AIS data, port data and berth data of a ship; a berthing berth and a berthing port of the ship and loading and unloading actions at the berthing port are judged through a specific judgment method, and then navigation data are obtained through statistics according to two continuous berthing data of the same ship in combination with load ton data in AIS data; the method comprises the following steps: acquiring navigation data of each ship, automatically extracting all ships meeting screening conditions within a time range, summarizing MMSI occurrence times and loading ton data of each ship according to the navigation data to obtain total navigation sub-sequence and total navigation loading ton of each ship, and displaying
