The invention relates to a ship collision risk analysis method, which comprises the following steps of: according to AIS dynamic data of ships of known types, constructing a neural network prediction model capable of judging ship types according to the AIS dynamic data; performing grid division on the target sea area; traversing all grids in the target sea area, and calculating collision elements of different types of ships in each grid according to the neural network prediction model; performing weighted linear superposition on the collision elements in each grid to obtain collision risk quantized values of different types of ships in each grid; and superposing the collision risk quantized values of the different types of ships in each grid within a preset time, dividing the collision risks of the different types of ships in each grid into a plurality of grades according to an equidistant division method, and carrying out risk grade visualization in a thermodynamic diagram form in a map. The ship collision risk level in the target sea area can be analyzed according to the AIS ship position data.
