DRIVERS OF SCIENTIFIC-TECHNOLOGICAL PRODUCTION IN BRAZILIAN HIGHER EDUCATION AND RESEARCH INSTITUTIONS

ABSTRACT This article estimates a knowledge production function for Brazilian universities, relating their inputs of scientific activity, such as the total of academic and administrative personnel and investments in scientific research, among others, to their outputs, such as the number of publications and patents. The article applies econometric models for count data, such as the Negative Binomial, for the 2003-2011 period. The overall results show that the main determinants of Brazilian scientific and technological production are the size of the university, its nature (whether public or private), the ratio of teaching staff and graduate students, and total investments in research and research support.

摘要 本文针对巴西高校构建并估计知识生产函数，将其科研活动投入（如学术与行政人员总量、科研经费投入等）与科研产出（如论文发表数量、专利数量等）建立关联。本文针对2003-2011年的样本，运用计数数据计量经济学模型（如负二项模型（Negative Binomial））开展实证分析。整体研究结果显示，巴西科技产出的主要影响因素包括高校办学规模、院校性质（公立或私立）、教学人员与研究生的配比，以及科研与科研支撑经费的总投入。
