摘要

本研究调查商用大型计算机市场的产品生命周期。我们表明,在产品层面进行的实证研究对于调查潜在产品生命周期的过程是有用的。我们用时变协变量的风险模型来估计产品退出的概率,用泊松模型来估计产品引入的概率。我们衡量了市场结构不同方面的重要性,如竞争程度、同类相食、年份、产品利基和企业效应。我们发现产品退出和产品进入的决定因素之间的关系的一些证据。

Dynamic Modeling of Product Life Cycle in the Commercial Mainframe Computer Market, 1968-1982
This research investigates product life cycles in the commercial mainframe computer market. We show that empirical studies conducted at the product level are useful for investigating processes underlying product life cycles. We use hazard models with time-varying covariates to estimate the probability of product exit and Poisson models to estimate the probability of introduction. We measure the importance of different aspects of market structure, such as the degree of competitiveness, cannibalization, vintage, product niche and firm effects. We find some evidence of a relationship between the determinants of product exit and product entry.
