Abstract 本研究では,まず,日米の産業別のIT 投資構造を比較分析し,日本産業をIT 生産・使用セクター及び非IT セクターに分類した。そのうえで,こうしたセクターの間,及び日米間の労働生産性の差異を検討した。それと同時に,セクター毎にVAR モデルを用いて,IT 投資の日本産業への生産効果に関する因果関係を分析した。主な結果は以下のように要約できる。日米の比較では,米国のIT セクター部門シェアは日本を大きく上回り,且つ労働生産性の成長率も90年代後半に目立って上昇している。日本の労働生産性成長率では,IT 製造業とIT サービス業が非IT の両部門を上回る傾向にある。IT 投資の生産性成長に対する因果関係は検証されなかったが,労働生産性の上昇がIT 投資を促進するという関係が認められた。また,サービス業におけるIT 投資成長率は,IT 部門と非IT 部門ともに製造業でのIT投資成長率によってプラスの影響を受けることが示された。
Abstract Alternative In this paper, we present comparisons of labor productivity growth between the IT sector and Non−IT sector in Japanese industries, and investigate the causal relationships between IT investment growth and labor productivity growth in both sectors. Based on VAR approach, our findings indicate that IT investment is not causing, but being caused by labor productivity growth, and show that the causality relationship exists from the IT investment in manufacturing industries to that in service industries.

Title Alternative How Do Chinese Listed Corporations Determine Capital Structure
FullText URL 40_1_001_030.pdf
Author Shi, Hongwei| Zhang, Xingyuan|
Abstract This paper investigates empirically how Chinese firms determine their debt equity ratios in recent 10 years. We use data abtained from the firms listed in the Shanghai Stock Exchange and Shenzhen Stock Exchange, and divide the sample into two periods, i.e., 1996−2000 and 2001−2005 to see if there is any change in the capital structure in these firms. Our results show that there exist effects of industry factors on the debt ratios of Chinese firms. However, the R−squared values are quite smaller than those in the USA and Japan. Our results also indicate that size, profitability, growth, non−tax effect and cash flow are important determinants of financing decisions in Chinese corporations, and in the period 2001−2005 growth becomes dominant factor, taking place of profitability in the period 1996−2000.
