信息产品版权销售方式选择

Sale Modes of Information Product Copyright

考虑由信息产品内容提供商、零售商和消费者构成的供应链结构,其中供应商为Stackelberg领导者。信息产品供应商与零售商之间的两种销售版权转让方式:固定费用定价和按份销售定价。建立了两种模式下的收益最大化模型,并在消费者异质化假设,且对产品评价值服从递增失效函数的分布下,从收益、产品质量及需求量等方面进行了比较。研究表明:供应商更愿意选择固定费用定价模式,而按份销售定价模式更利于零售商;但从供应链整体收益来看,固定费用定价模式更有利。

An information product supply chain, consisting of an information product content provider, as the Stackelberg leader, a retailer and the consumers, are studied. The copyright can be sold based on two policies： fixed-fee policy and per-copy policy. In order to compare these two policies with regard to the profits, product quality and the demand, the model of maximizing the profit is constructed, subject to the assumption of heterogeneous consumers and that the valuation distribution of the products is an increasing hazard function. The results show that the supplier prefers the fixed-fee policy to the per-copy; On the contrary, the retailer prefers the latter policy. However, the fixed-fee policy is more preferable with regard to the whole supply chain＇s profit.
