本文从技术扩散文献的角度研究了新技术对生产率的影响。我们认为，一些程式化的事实，企业内扩散过程中没有考虑到在目前的研究，这可能会导致错误的结论。我们批判性地评估不同的方法，已采取的技术采用对生产率的影响时，研究，并将它们与文献的主要研究结果技术扩散的目的是确定一个企业内扩散方法的优势。然后，我们进行实证分析的样本，描述了一个创新的扩散-自动柜员机-西班牙储蓄银行之间从1986年至2004年在其广泛的（公司间）和密集的（公司内）的尺寸。我们的研究结果表明，只有考虑企业内扩散过程才能解释技术对生产率的贡献。
This paper studies the impact of new technologies on productivity from the perspective of the technological diffusion literature. We argue that several stylised facts about the intrafirm diffusion process are not taken into account in most current research, which results in potentially erroneous conclusions. We critically assess different approaches that have been taken when studying the effects of technology adoption on productivity, and relate them to the main findings of the literature on technology diffusion with the aim of identifying the advantages of an intrafirm diffusion approach. We then conduct an empirical analysis on a sample that describes the diffusion of an innovation – the Automated Teller Machine – among Spanish savings banks from 1986 to 2004 in both its extensive (interfirm) and intensive (intrafirm) dimensions. Our results show that only the consideration of the intrafirm diffusion process is able to account for the contribution of the technology to productivity.
