Surviving the gales of creative destruction: the determinants of product turnover
研究了激光打印机行业中产品更替的决定因素，发现市场竞争、企业市场份额和创新能力显著影响产品进入和退出市场的速度。
Abstract Innovative industries are often characterized by rapid product turnover. Product longevity may be driven by both a product's position within a market as well as its position within a firm's larger product portfolio. However, we have little understanding of the relative importance of these factors in determining product turnover and how they interact as an industry evolves. Although researchers have invested substantial effort in analyzing firm survival and turnover, there are far fewer studies of the determinants of product survival and turnover. We use hazard rate models and count regression models to describe the behavior of firms and their products with a new and detailed database on the laser printer industry. We show, first, that competition and market structure variables have a large impact on both speeding product exit and delaying product entry. Second, there is some evidence that firms that have maintained a high market share for a number of years keep their products on the market longer than those with lower market share. Finally, firms with high innovative capacity tend to enter markets frequently, but withdraw their products at average rates. Firms with strong brands tend to introduce few products and withdraw their products slowly. With these findings, the paper links product entry and exit decisions to the broader literature on firm strategic and product management. Copyright © 2006 John Wiley & Sons, Ltd.
