報告摘要：Conventional wisdom suggests that capacity expansion could increase (at least not decrease) firms’ profits. This paper shows that this does not always hold for 3D printing products with limited capacity. We develop a game model in which two firms have a chance to produce 3D printing products by investing in 3D printing technology. Generally, the capacity of 3D printing products is limited relative to the traditional products and the firms usually spend a fixed cost to prepare production. We first analyze the case of monopoly which is served as a benchmark. Then, we examine the competing case in which we characterize the equilibrium 3D printing strategy for the two firms. In the case of monopoly, it is intuitive that the firm can benefit from 3D printing if the fixed cost is not too high. However, in the competing case, it is interesting that the two firms may be involved into a prisoner’s dilemma. That is the optimal strategy for each firm is to give up 3D printing, but the equilibrium strategy is to embrace 3D printing. Furthermore, we find the firm gains more profit (not strictly) in the monopoly case with capacity of 3D printing increasing. In the competing case, surprisingly, we find that one firm’s profit may decrease as the capacity increases. At last, we verify the robustness of the model and find the main findings are valid even if several assumptions are relaxed.
