项目摘要

To clarify the contribution of the change of social structure by information technology revolution to labor productivity and it's growth since 1990 in U. S. A. and Japan, I developed the econometric model which divide the capital stock into the information-related capital stock and the other capital stock to estimate the production function.The theory of New Economy has been emphasized that the 1990's economic growth in U. S. A. has depended on the information technology revolution. But we could not find such relationship before the change of estimation method of GDP at October 1999. However, we become to be able to confirm the above relationship by using the date of 93NA after 2000.By using the above my econometric model and 93SNA date, I could also get the following significant results.(1) The information-related capital stock gives positive effect to labor productivity growth since 1990 in U. S. A. and Japan. So, I think the productivity paradox disappeared in 1990's at U. S. A. and Japan.(2) Comparing the determinant of labor productivity between U. S. A. and Japan, Japanese contribution rate of information-related capital stock deepening by information technology revolution is still lower than that in U. S. A.(3) Comparing the determinant of labor productivity growth between U. S. A. and Japan, Japanese contribution rate of information-related capital stock per man-hour of employment is smaller than that in U. S. A.From the above results, in Japan, The accumulation of the information-related capital stock is necessary by all means to get out of long stagnation after the collapse of bubble.

阐明信息技术革命引起的社会结构变化对美国1990年以来劳动生产率及其增长的贡献。S. A.本文借鉴美国和日本的经验，将资本存量分为信息相关资本存量和其他资本存量，建立了计量经济模型来估计生产函数。S. A.依赖于信息技术革命。但在1999年10月GDP估算方法改变之前，我们并没有发现这种关系。然而，2000年以后，我们开始能够用93 NA的数据来证实上述关系。通过使用我的上述计量经济模型和93 SNA数据，我还可以得到以下显著结果。(1)1990年以来，美国信息相关资本存量对劳动生产率的增长起到了积极的促进作用。S. A.和日本所以，我认为生产率悖论在20世纪90年代的美国已经消失了。S. A.和日本(2)比较了中美两国劳动生产率的决定因素。S. A.日本信息技术革命对信息相关资本存量深化的贡献率仍低于美国。S. A. (3)比较了中美两国劳动生产率增长的决定因素。S. A.与日本相比，日本的单位工时信息资本存量贡献率小于美国。S. A.从上述结果来看，在日本，信息相关资本存量的积累是摆脱泡沫破裂后长期停滞的必要手段。
