Abstract

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.
巴西背景下创新扩散的动态
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。
