Recent productivity growth: the role of information technology and other innovations
质疑信息技术是1990年代中期以来美国生产率加速增长的主要驱动力的观点，认为文献可能过度强调了信息技术的作用，而其他创新同样重要。
I am pleased to be talking about one of the truly salient issues for the economy today to such a distinguished audience. The acceleration in productivity growth since the mid-1990s has been an exceptionally important development for the U.S. economy. My remarks are going to run somewhat contrary to the view that information technology has been the overwhelming impetus to the acceleration in productivity growth in recent years. While technology and in particular information technology (IT) are obviously very important drivers of productivity, I want to make the case that perhaps they have been overemphasized in the literature. This might sound a little subversive in the context of this conference; but it really is not, since my comments are entirely consistent with the broader theme running through the sessions, that productivity is linked to innovation.
