The Input-Output model assumes that as economic systems develops, the technical coefficient matrix changes following either of two tendencies; one, the entries of the matrix shrink due to increased efficiency on the production lines; two, they expand, while productivity gains concentrate in the use of factors (nonproduced inputs). Further, the economic structure grows more complex as industries become more tightly (vertically) integrated and the development process evolves. Both phenomena have seldom been analysed together despite the apparent connections those may have with the evolution of economic structures and the development opportunities countries may face. This paper intend to examine the implications of these tendencies on the evolution of the economic systems in regards to the dynamics the growth process may adopt.// El modelo de insumo-producto supone que cuando se desarrolla el sistema económico los coeficientes técnicos de la matriz cambian de acuerdo con dos tendencias contradictorias: i) las entradas de la matriz menguan debido a que la eficiencia en la línea de producción se incrementa, disminuyendo la demanda de insumos, o ii) los coeficientes se expanden, cuando los incrementos en la productividad se concentran en los factores empleados (insumos no producidos). En seguida, se espera que la estructura económica se torne crecientemente más compleja a medida que las industrias se integran de manera vertical y se produzca el proceso de desarrollo mismo. Sin embargo pocas veces se han analizado ambos fenómenos al mismo tiempo, a pesar de que están muy vinculados entre sí, y también con la evolución de la estructura productiva de la economía, así como con las oportunidades de desarrollo que se presentan a los distintos países. Este documento intenta examinar algunas consecuencias de estas tendencias en la evolución del sistema económico en relación con la dinámica que pudiera adoptar el proceso de crecimiento.
