The present invention relates to the technical field of electronic commerce, and provided thereby are a pricing method performed by a computer and device, and a non-transient computer-readable storage medium. The pricing method includes: determining a price vector to be tested and a reference conversion rate score according to a set of price vectors and a conversion rate score corresponding to each price vector, wherein each price vector in the set of price vectors comprises the price of one or more inventory units in the same period; selecting an optimization direction according to a result of comparison between the conversion rate score corresponding to the price vector to be tested and the reference conversion rate score, and determining an optimized price vector on the basis of the optimization direction; and updating the current price of the inventory unit using the price in the optimized price vector.
