Em economias em desenvolvimento, a aquisição de uma nova máquina pode significar para a firma a introdução de um novo produto ou um novo processo para a empresa ou para o mercado doméstico. Este texto busca avaliar a importância das introduções de inovações via tecnologia incorporada em novas máquinas e equipamentos. Para tal, verificou-se o impacto de tais aquisições sobre a produtividade das firmas industriais brasileiras. Visando controlar possíveis relações de simultaneidade e autosseleção existentes entre as variáveis envolvidas, estima-se um sistema de equações estruturadas. Os resultados encontrados demonstram a existência de impactos positivos e significantes, advindos do investimento em capital físico sobre a inovação tecnológica das firmas. O efeito médio do tratamento advindo da inovação em processo apresenta impacto positivo sobre a produtividade do trabalho. O tamanho da firma possui papel relevante na determinação da decisão de investir, no montante do investimento e sobre as diferentes formas de inovação tecnológica. In developing economies the purchase of a new machine by the firm can be a way of introducing a new product or processes. Under such considerations, this paper searches to measure the assumption of innovation via machine embodied technology, by verifying its impacts over the firm’s productivity. In order to control for possible simultaneity and self-selection relationship between the variables a structured system of equations is estimated. The found results reveal the existence of positive and statistically significant impacts from the investments decision on technological innovation over the firm’s productivity. The treatment effect estimated for product and process innovation presents positive and significant impact over the labor productivity. The firm size seems to be an important role in shaping the invest decision, the investment intensity choice and the different forms of technological innovation.
