我们将扩散效应和选择效应纳入一个综合模型，以同时捕捉一项持久技术每一代的扩散和替代过程。选择文献通常忽略需求动态，以前的多代扩散模型很少包括控制变量。所提出的模型是两种方法的结合。该模型的基本前提是，新产品替代旧产品是基于消费者的选择行为，即消费者选择产品以最大化其效用。然后，我们可以推导出选择概率、扩散过程和营销组合变量之间的隐含关系。为了验证所提出的模型，我们还分析了IBM大型机市场和全球DRAM（动态随机存取存储器）市场。(C) 1999 Elsevier Science Inc.；
We incorporate diffusion effects and choice effects in an integrated model to capture simultaneously the diffusion and substitution processes for each successive generation of a durable technology. The choice literature generally ignores demand dynamics and previous multigeneration diffusion models rarely include control variables. The proposed model is a combination of the two approaches. The basic premise of the proposed model states that the replacement of an older product by a newer one is based on the choice behavior of consumers, where consumers choose a product to maximize their utility. Then we can derive the implied relationships among choice probabilities, diffusion processes, and marketing mix variables. To verify the proposed model, we also analyze the IBM mainframe market and worldwide DRAM (dynamic random access memory) market. (C) 1999 Elsevier Science Inc.
