ABSTRACT

This article develops a modeling framework for growth and innovation in which accumulation dynamics of knowledge and R&D are explicitly considered. The framework is based on a more general knowledge production process than commonly used in Endogenous Growth Theory and R&D productivity literatures, reconciling as special cases disparate analytical approaches. The proposed model of knowledge dynamics highlights the role of human and physical capital accumulation in the creation of innovations and cautions against their omission in empirical models. Econometric analysis largely supports the model's predictions.

知识和研发积累动态下的增长和创新

摘要

本文开发了一个增长和创新的建模框架，其中明确考虑了知识和研发的积累动态。该框架基于比内生增长理论和研发生产力文献中常用的更通用的知识生产过程，作为特殊情况协调不同的分析方法。所提出的知识动态模型强调了人力和物质资本积累在创新创造中的作用，并告诫不要在经验模型中遗漏它们。计量经济分析在很大程度上支持模型的预测。
