Esto se lleva a cabo a través de diferentes indicadores de actividad legislativa, como el caso de la producción normativa, la revisión de decretos, el control al ejecutivo y la conformación partidaria del Legislativo y de sus órganos de gobierno, entre otros. Como resultado de ello, se evidencian diferentes etapas en las relaciones Ejecutivo-Legislativo, con un marcado distanciamiento y final aislamiento del oficialismo, el cual tendió a una creciente inestabilidad y dificultad para desplegar su agenda de gobierno. Por parte del Congreso, se observa una elevada inestabilidad, volatilidad y crecientes dificultades para articular mayorías que permitan llevar a cabo sus funciones como Poder Legislativo. La baja institucionalización del sistema de partidos y la precaria estructuración de estas organizaciones explican, al menos parcialmente, los efectos limitadores que se produjeron en el funcionamiento de los poderes Ejecutivo y Legislativo y de su distanciamiento progresivo.This study analyzes the Peruvian party system between 2001 and 2016 and its effects on the functioning of the Congress of the Republic through different indicators of legislative activity, such as normative production, revision of decrees, and control of the executive and partisan conformation of the legislature and its governing bodies, among others. As a result, different stages in executive-legislative relations are evidenced, with a marked distancing and final isolation of the ruling party, which tends to increase instability and difficulty in deploying its government agenda. Congress had a high degree of instability, volatility, and growing difficulties in articulating majorities that would allow it to carry out its functions as a legislative power. The low institutionalization of the party system and the precarious structuring of these organizations explain, at least partially, the limiting effects on the functioning of the executive and legislative branches and their progressive distancing.81-98esopenAccessPerúPartidos políticosPoder legislativoPoder ejecutivoCongresoarticuloAutores y UNR Editorahttps://doi.org/10.35305/tyd.vi47.668Attribution-NonCommercial-ShareAlike 4.0 International You are free to: Share — copy and redistribute the material in any medium or format Adapt — remix, transform, and build upon the material The licensor cannot revoke these freedoms as long as you follow the license terms.
