电脑软件存在的网络效应使得厂商定价策略发生一定的变化。本文运用动态最优化理论,分析电脑软件厂商的定价策略和最优更版时机。发现厂商通常会以先低于边际成本的价格定价,然后逐渐提高软件的价格,与不具有网络效应的产品的边际成本定价有一定差异;厂商在升级旧版软件时,存在最佳时机,过早或者过迟推出新版软件都将导致利润损失。 The network effect of computer software makes some changes to the pricing strategy of manufacturers. In this paper, the dynamic optimization theory is used to analyze the pricing strategy of computer software vendors and the optimal timing of versioning. It is found that manufacturers usually price at a price lower than the marginal cost first, and then gradually raise the price of the software, which is different from the marginal cost pricing of products without network effects. There is a best time for manufacturers to upgrade old software, Or late release of new software will result in loss of profits.
