There is consensus regarding the fact that the change in total factor productivity CTFP) rather than the rate of capital changes in efficiency interms of in capita GDP countries. variations are with the use of production factors not explained their accumulation and that, in the term, are more greatly associated to the process of technological progress and company innovation. This thesis is Using the an effort to contribute to the study of firm-level innovation, in the particular Chilean manufacturing firms Innovation Survey (EIT together with the Ann National Industrial Survey an econometric Technologica spending mod to identify factors from the determinants of innovation efforts to the impact of order to study ovation and in order performed in by its performance in productive and export activity. In turn, causality tests are made spending, exports and productivity inte with one other. Among the contributions this work in relation to the relevant follows. First, we study firms' spending on innovation activities, de like previous studies that study the R&D expenditure. This allows us to cover a range of companies, which pite not making significant efforts are undertaking other innovative activities. This is the case of Chile where only a few hundred companies perform R&D. The second distinctive contribution is that this study con siders data from 1995-2010, which makes up the greatest collection of data studied on the topic and thus us to assess the evolution of innovation over the past fifteen years. Finally, in this paper, the relationship between innova tion and exports is analysed as well as the extent to which firms increase their innovation efforts by participating in international markets. Consistent with previous studies, we find evidence of the Schumpeterian hypothesis, referring to the influence of the size of a firm on innovative activity Also, it is observed that firms that have a good performance in terms of export We have been and production, in turn, invested in innovation, allowing them to develop new products and processes. able to conclude that, according to the manufacturing sector and the year studied, there is a high dependence on relationship of these variables. For the years of a low exchange rate (a variable that strongly affects the cycle of the national economy) self-selection is observed. Causality also depends on the industry that is being studied, This beco mes evident in both selfselection and learning by exporting, where spending on innovation interacts indirectly shed light on the fact that macro factors, such as energy prices and the exchange rate, affect the measurement of inno vation performance and the decision of spending on innovation, respectively.
