本文对1951- 1978年期间电力工业的技术变化率进行了估计。估计模型直接纳入收益率监管的影响，并使用时间趋势和年份指数分别代表无形和具体的技术变化。结果表明，无形的技术变革是1951- 1970年期间成本降低的主要来源，而更严格的监管，如回报率降低一个百分点，将使1951- 1978年期间的技术变革率平均降低1%-2%。34篇参考文献，18个脚注，3个表格。
This paper presents estimates of the rate of technical change in the electric power industry over the period 1951-78. The estimated model directly incorporates the effects of rate-of-return regulation, and uses both a time trend and a vintage index to represent disembodied and embodied technical change, respectively. The results indicate that disembodied technical change was the primary source of cost reduction during 1951-70, and that tighter regulation, as represented by a one point reduction in the rate of return, would have reduced the rate of technical change by an average of 1%-2% during 1951-78. 34 references, 18 footnotes, 3 tables.
