The present work designs an index of the impact of innovation in Chilean technology centres. A database derived from the 10th innovation survey conducted by the National Institute of Statistics of Chile was generated. The instrument had 321 questions and included 5,876 organisations. The variables were reduced using inclusion-exclusion criteria, confirming 15 high-impact items to generate second-level dimensions. Through exploratory factor analysis and comparing the component matrix with the rotated component matrix, three latent dimensions explaining more than two-thirds of the total variance were ratified. It was determined that the dimensions: innovation in marketing, descriptors of innovation, and internal innovation make up the innovation model. The dimension ‘descriptors of innovation’ includes the items with the greatest impact and gives rise to an index for designing an innovation ranking in Chilean technology centres.
