On Interindustry Differences in Absolute Productivity
探讨行业间绝对生产率水平比较的含义与意义，指出基年权重适用于衡量生产率增长而非绝对水平，而现价权重虽能衡量绝对生产率但会因资源再分配机制导致各行业趋同。
In the literature, comparisons between absolute levels of productivity in different industries occur frequently. This paper explores the meaning and possible significance of such measures. Prices must be used to permit the required comparison of the outputs of different industries. It is shown that base-year weights produce a valid measure of productivity growth but not of absolute productivity level. Current price weights do yield a valid index of absolute productivity but one that tends to be equal for all industries because of the general equilibrium mechanism that reallocates resources from low-productivity to high-productivity industries.
