Derramamientos sectoriales de conocimiento e innovación en la industria manufacturera colombiana: un análisis multinivel Mauricio Losada-Otálora Julio César Zuluaga Administración y Contabilidad El propósito de esta investigación es analizar la relación que existe entre los derra- mamientos sectoriales de conocimiento y el desempeño innovador de las firmas manufactureras colombianas. Se desarrolla un modelo de regresión Poisson multinivel para analizar estos efectos, teniendo en cuenta la estructura anidada y jerárquica de los datos. Una base de datos de 4.780 pequeñas y grandes empresas colombianas que operan en 66 sectores se utiliza en el estudio. El análisis simultáneo de variables de nivel de firma y de nivel sectorial muestra una relación positiva entre el desempeño innovador de las empresas y los derramamientos sectoriales de conocimiento, tal que la innovación de estas depende de sus propios esfuerzos y de la innovación alcanzada por sus competidores, proveedores y clientes. Estos resultados sugieren que las empresas en países en desarrollo, ante las limitaciones internas y externas para innovar, se pueden beneficiar del conoci- miento generado por las firmas con las que compiten y del conocimiento generado por las firmas de sectores con las que establecen relaciones de intercambio. 2013 artículo científico 0121-5051 https://www.redalyc.org/articulo.oa?id=81827443002 es http://www.redalyc.org/revista.oa?id=818 INNOVAR.
