本文从资本和劳动所得的分配结果出发,建立产业结构变动与资本收益率变动、人均劳动者报酬变动之间,以及资本收益率变动、人均劳动者报酬变动与产业技术水平变动之间的实证模型,利用美国1987～2007年60个产业的面板数据检验实证模型中变量之间的相关关系,确定产业结构演变的内在动因及其作用机制。研究结果表明,产业结构演变的直接动因是产业资本收益率和人均劳动者报酬的变动,而产业资本收益率变动和产业人均劳动者报酬变动的直接动因是产业技术进步。
Based on the distribution of capital and labor income, this paper establishes an empirical model of the relationship between changes in industrial structure and return on capital, changes in remuneration per worker, as well as changes in the rate of return on capital, changes in remuneration per worker and changes in industrial technology , Using panel data of 60 industries in the United States from 1987 to 2007 to test the correlation between the variables in the empirical model to determine the intrinsic motivation and mechanism of the evolution of industrial structure. The results show that the direct cause of the evolution of industrial structure is the rate of return of industrial capital and the change of per worker’s remuneration. The direct motivation for the change of return rate of industrial capital and the per capita reward of industrial performers is industrial technological progress.
