Analysis of indicators of intensity of P&D: understanding the effects of the industrial structure and sectoral expenditures

Abstract: This article examines the determinants of R&D business expenditures through an R&D intensity indicator defined by the ratio between R&D expenditures and industry value added. With the decomposition of its determinants, the objective of this article is to identify the extent to which Brazil's distance in terms of technological efforts, measured by such indicator, in relation to the average of a set of selected countries, can be attributed to the effects of the industrial structure R&D expenditures made by the different technology groups that make up this industry.

摘要：本文以研发（R&D）支出与产业增加值之比所定义的研发强度指标为工具，探究企业研发支出的决定因素。通过对该指标的决定因素进行分解，本文旨在厘清：以该指标测算的巴西技术投入水平，与一组选定国家的平均水平相比所存在的差距，在多大程度上可归因于构成该产业的不同技术组别所产生的产业结构研发支出效应。
