项目摘要

1.We conducted a survey of Japanese firms listed in the stock exchange market in Feb.2002. It tells that (1) the number of workers controlled by supervisor decreases in manufacture but increases in non-manufacture compared with 3 years before. (2)Investment for education decreases. (3)PC has been networked intensively.2.Compiling firm' s survey data and its financial statements, a Cobb-Douglas production function is used to test relationships between productivity, IT, human resources and workplace organization. The result reveals that (1)combinations of high-level IT and high-level human resources promote productivity of Japanese firms. (2)the combinations of high-level IT and human resources, and the centralized organizational structure promote productivity. (3)complementary relationships between IT, human capital and working organizational structure changes after the Internet diffusion.3.Market value of firm is regressed to its capital stock, land, other assets, inventory, R&D stock, advertisement stock, IT index, human capital index and organizational structure index, we obtain (1)adoption of IT increases firm' s market value. Its effect in manufacture is twice of the effect in non manufacture. (2)In manufacture, combinations of high-level IT and high-level human resources promote its market value. (3)When IT is used in centralized structure, its farm' s market value is promoted in Japan, contrary to U.S.

1.我们对2002年2月在证券交易所上市的日本企业进行了调查。研究结果表明：（1）与3年前相比，制造业主管控制的工人数量有所减少，而非制造业主管控制的工人数量有所增加;（2）教育投资减少。(3)PC 2.在整理企业调查数据和财务报表的基础上，利用柯布-道格拉斯生产函数检验了生产率、信息技术、人力资源和工作场所组织之间的关系。结果表明：（1）高水平IT和高水平人力资源的结合促进了日本企业的生产率。（2）高水平的IT和人力资源的结合，以及集中的组织结构促进了生产率。（3）信息技术、人力资本与工作组织结构之间的互补关系在互联网扩散后发生了变化。3.将企业的市场价值回归到其资本存量、土地、其他资产、存货、R&D存量、广告存量、信息技术指数、人力资本指数和组织结构指数，我们得到：（1）信息技术的采用增加了企业的市场价值。它在制造业中的作用是在非制造业中的作用的两倍。(2)In制造业，高水平的IT和高水平的人力资源的组合，提高其市场价值。（3）在日本，信息技术在集中式结构中的应用，促进了农场的市场价值，而美国则相反。
