Abstract: In the buyer's market, the dominant retailers often introduce two or more suppliers that produce homogenous products to meet their own needs and obtain higher benefits through competition among suppliers. Price competition is an important means for suppliers to compete for market share. However, under the premise of sufficient production capacity, the result of competition will be that neither party will be profitable. From the perspective of production capacity, this paper uses the newsboy model to analyze the effect of competition on suppliers and retailers under different production capacity for two suppliers producing homogeneous products. By analyzing and comparing the two situations of symmetry and asymmetry capacity, we find that retailer can always benefit from competition, while for competing suppliers, productivity capacity should be restricted to a certain extent. Finally, we obtain some inspiration from management.
