R & D Capital, Rate of Return on R & D Investment and Spillover of R & D in Japanese Manufacturing Industries
利用更精确的企业研发支出数据，构建研发资本序列，估计日本制造业的研发投资回报率，并分析其他行业研发对某行业生产率增长的影响，特别关注电子技术通过中间品交易和知识扩散的溢出效应。
The effect of R$50D on productivity growth in Japanese manufacturing industries is examined. Using more accurate firm R$50D expenditure data than widely used data based on financial statements, series of R$50D capital are constructed. Then, rate of return on R$50D investment is estimated. In addition, the impact of other industries' R$50D on the productivity growth of an industry is also estimated. An attempt is made to determine the effect of electronics technology upon the productivity growth of other industries through the transaction of the intermediate electronics goods with improved quality, and through the diffusion of the new technological knowledge discovered.
