Abstract: With the advancement of Internet information technology,the laborer-sharing platform plays a crucial role in promoting the full use of human resources across the whole society. At present, multiple trading modes with different pricing strategies are adopted by the laborer-sharing platform. Considering the heterogeneity of laborers’ abilities, we construct the laborer-sharing platform’s profit functions under the buyer pricing strategy and laborer pricing strategy, and analyze its optimal pricing strategy in the bidding mode.First, our analysis shows that when the mismatch degree between the service of the low-type laborer and the buyer’s task is close to that of the high-type laborer, the laborer pricing strategy is beneficial to the platform. Second,when the task mismatch degree of the low-type laborer is much lower than that of the high-type laborer, the platform’s pricing strategy depends on the buyer’s satisfaction with the completing task. Finally, we compare two transaction models: the bidding mode and the piece mode, and find that under the laborer pricing strategy, the platform’s profit in the bidding mode is not always higher than that in the piece mode.

Key words: laborer-sharing, bidding mode, piece mode, buyer pricing strategy, laborer pricing strategy
