Producing Synergy: Innovation, IT, and Productivity
研究信息技术如何通过过程导向的研发知识存量提升全要素生产率增长，并增强IT资本的生产率效应，基于1987-2005年美国行业面板数据发现研发与IT投资存在协同效应。
ABSTRACT Bringing innovations to market is critical to industrial progress and economic growth. We explore the potential for information technology (IT) to enable innovations, and thus improve productivity. We hypothesize that a knowledge stock of process‐oriented research and development (R&D) increases total factor productivity growth by leveraging traditional forms of capital and labor, and further enhances the ability of IT capital to increase productivity. We estimate these relationships using two broad panels of U.S. industries covering the periods 1987–1998 and 1998–2005. The results indicate qualified support for a synergistic effect of R&D and IT investment in both periods.
