本文阐述了 Rosenberg 的 [Rosenberg, N., 1982。黑匣子内部：技术与经济。剑桥大学出版社，剑桥]“使用学习”作为一个随机过程。机器的生产者从用户的经验中学习。由于这种学习，机器的质量会随着时间的推移而提高。事实证明，这种改进的过程近似呈指数形式。这种改进过程，加上改进带来的需求增长，可以产生机器的S形扩散曲线。强烈的需求和通信技术的进步提高了传播速度。还探讨了随机过程的分布特性以及机器用户之间不平等的影响。 (c) 2005 Elsevier B.V. 保留所有权利。
This paper formulates Rosenberg's [Rosenberg, N., 1982. Inside the Black Box: Technology and Economics. Cambridge University Press, Cambridge] "learning by using" as a stochastic process. The producer of machines learns from the experience of users. Due to this learning, the quality of machines improves over time. It turns out that the process of this improvement takes an approximately exponential form. This improvement process, combined with the growth of demand due to the improvement, can produce an S-shape diffusion curve of machines. Strong demand and advancement of communication technology increase the diffusion speed. The distributional property of the stochastic process and the implications for inequality across machine users are also explored. (c) 2005 Elsevier B.V. All rights reserved.
