英文文献：Product Life Cycles and the Adoption of Durable Inputs: An Example for the Tomato Harvester
英文文献作者：Carman, Hoy F.,Brandt, Jon A.
英文文献摘要：
A theoretical framework is developed for product life cycles of durable. inputs and then is empirically tested using the logistic growth function to explain mechanical tomato harvester adoption. Reasons for the rapid adoption of the mechanical harvester are offered; implications for new markets and replacement sales are discussed.
