摘要

创新和传播是复杂的概念。理解创新的扩散意味着推进有关技术进步的知识。在文献中有一种理解,即扩散是依赖于环境的。本文的目的是分析创新在巴西的扩散,考虑到他们的社会经济特殊性。根据国家调查(PNAD)收集的六种产品在不同时期的消费数据,根据Rogers(1962)估计扩散曲线,根据Bass(1969)计算系数。主要结果是:1)该模型对巴西的扩散分析是有用的,表明罗杰斯和巴斯的理论也适用于这一背景;2)所研究产品的扩散在经济中处于不同阶段,本质上是一个模仿过程;3)应考虑巴西经济的扩散特性,因为似乎存在使其分化的内生因素。

Dinâmica da difusão de inovações no contexto brasileiro
Innovation and diffusion are imbricated concepts. Understanding diffusion of innovations means advancing knowledge about technological progress. There is in the literature the understanding that diffusion is context-dependent. The objective of this paper was to analyze the innovations diffusion in Brazil, considering their socioeconomic particularities. With consumption data collected from a national survey (PNAD) for six products in different periods, diffusion curves were estimated from Rogers (1962) and coefficients calculated according to Bass (1969). The main results were: 1) the model was useful for the diffusion analysis in Brazil, stating that Rogers and Bass are relevant theories also for this context; 2) the diffusion of the products investigated is in different stages in this economy, and is, essentially, an imitation process; and 3) should be considered the diffusion peculiarities for the Brazilian economy, since there seems to be endogenous factors that make it differentiated.
