¿Qué quieren las empresas de las universidades? Oportunidades de colaboración para desarrollar innovaciones Manuel Lobato Vico Myrna Rivas Nina José Vega Torres Administración y Contabilidad Empresa patentes innovación universidad colaboración Las universidades son un elemento clave en los sistemas de innovación, especialmente cuando se establecen mecanismos eficientes de transferencia de conocimientos con las empresas. Este artículo analiza oportunidades de colaboración entre universidades y empresas. La revisión de literatura enfatiza el interés de las empresas en obtener conocimiento nuevo, en la asistencia en la solución de problemas - con servicios especializados-, y en la formación de personal. El trabajo de investigación realizado en Puerto Rico, basado en entrevistas a investigadores académicos, empresarios y otras personas vinculadas al sistema de innovación, confirma el interés local en esas áreas y destaca la oportunidad de ampliar las colaboraciones mediante estrategias flexibles. 2015 artículo científico 1541-8561 https://www.redalyc.org/articulo.oa?id=63158923001 es http://www.redalyc.org/revista.oa?id=631 Forum Empresarial application/pdf Universidad de Puerto Rico Forum Empresarial (Puerto Rico) Num.1.1 Vol.3
