美国经济在过去几年的表现令人瞩目，包括劳动生产率在经历了近四分之世纪的缓慢增长后出现反弹。为了评估信息技术在最近的反弹中的作用，本文重新审视了计算机和相关投入的增长贡献，与我们在早期工作中使用的新古典主义框架相同。我们的研究结果表明，信息技术（包括计算机硬件、软件和通信设备）的使用对生产率增长的贡献在20世纪90年代后半期大幅上升。此外，计算机生产的技术进步似乎对生产力增长的加速作出了重要贡献。总括而言，我们估计，在1990年代上半期至下半期生产力增长上升1个百分点的过程中，约三分之二是由于使用资讯科技和生产电脑所致。因此，要回答本文标题中提出的问题，信息技术在很大程度上是故事。
The performance of the U.S. economy over the past several years has been remarkable, including a rebound in labor productivity growth after nearly a quarter century of sluggish gains. To assess the role of information technology in the recent rebound, this paper re-examines the growth contribution of computers and related inputs with the same neoclassical framework that we have used in earlier work. ; Our results indicate that the contribution to productivity growth from the use of information technology - including computer hardware, software, and communication equipment - surged in the second half of the 1990s. In addition, technological advance in the production of computers appears to have contributed importantly to the speed-up in productivity growth. All in all, we estimate that the use of information technology and the production of computers accounted for about two-thirds of the 1 percentage point step-up in productivity growth between the first and second halves of the decade. Thus, to answer the question posed in the title of this paper, information technology largely is the story.
