The Rogers model of innovation diffusion, first proposed in 1962, has long featured in accounts of the penetration of new product technologies into society. The contention in this paper is that this model is in fact only half complete, for it deals exclusively with the uptake of new technologies rather than their retention or abandonment. Taking the Rogers model as a point of departure, this paper seeks to draw on the literature on nostalgia to characterize consumers who retain a specific technological artefact in the form of the car, then identify business models designed for those consumers.

The paper therefore analyses the relatively neglected contribution of extended product lifetimes within circular economies and within the broader concept of socio-technical transitions for sustainability. The relevance of this contribution is that product longevity is one means by which lifestyles characterised by material affluence are reconciled with resource scarcity. Product longevity has the potential to contribute to slowing down the ‘velocity’ of material flows within the circular economy, and hence to the deferment of the investment of further energy (and materials) into the next cycle of consumption.

Taking examples from the automotive industry and cars, the paper argues that the ‘post-peak’ (or post-production) retention of technologies may offer insights into both the viability and character of business opportunities, and a possible transition pathway into a post-consumer economy. The attraction of the post-production economy is in turn attributed to the concept of consumer nostalgia through which emotional engagement is translated into alternative forms of production and consumption.

1962年首次提出的罗杰斯创新扩散模型长期以来一直以新产品技术向社会的渗透为特征。本文的争论点在于，该模型实际上仅完成了一半，因为它专门处理对新技术的采用，而不是对新技术的保留或放弃。本文以罗杰斯（Rogers）模型为出发点，力求借鉴怀旧文献，以保留以汽车形式保留特定技术制品的消费者为特征，然后确定为这些消费者设计的商业模式。

因此，本文分析了在循环经济和可持续发展的社会技术过渡的更广泛概念内，延长产品寿命的相对被忽略的贡献。这种贡献的意义在于，产品寿命是使以物质富裕为特征的生活方式与资源稀缺相协调的一种手段。产品寿命可能会减缓循环经济中物质流动的“速度”，从而将更多能源（和物质）的投资推迟到下一个消费周期。

以汽车行业和汽车行业为例，该论文认为，技术的“高峰后”（或后期生产）保留可以提供有关商机的可行性和特征的见解，以及向后商贸的可能过渡途径。消费经济。生产后经济的吸引力反过来归因于消费者的怀旧观念，通过这种观念，情感参与转化为生产和消费的替代形式。
