Abstract: According to the relations among the retailing cost, market demand and retailing price in the supply chain, the enterprises profits between horizontal integration and vertical integration are compared. Employing the classical "newsboy problem" model, horizontal integration is found to reduce total costs of the channel system between the retailer and manufacturer, decrease the purchasing price and increase the manufacturers profit. Numerical analysis is then used to demonstrate that the manufacturer is willing to outsource the retail business to the retailer when the retailers retail cost is lower enough than the manufacturers cost.

Key words: supply chain, newsboy problem, horizontal integration, vertical integration
