B a c k g r o u n d . Global changes that have occurred in social relations in the world and in Ukraine recently, related to the environmental crisis, the Covid-19 pandemic, the full-scale war of the Russian Federation against Ukraine, require the systematization of scientific knowledge about parliamentarism as a special system of public management, in which the priority role in the formation of state policy, the parliament is the only legislative body of state power. The purpose of the study is to substantiate the traditions of people's representation and the values of political and administrative leadership, political responsibility and innovative activity of the parliament as those that contribute to the democratic development of Ukraine in the conditions of global changes. Object of study is parliamentarism in conditions of global changes. M e t h o d s . A complex of general scientific and special scientific research methods was used for: formulating the main concepts and conclusions of the research (method of theoretical analysis); comparison of legislative acts (method of comparative analysis); forecasting ways to improve the quality of the activity of the parliament and parliamentarians in the conditions of global changes, taking into account the modern values of parliamentarism, such as ethical leadership and innovative activity in public administration (methods of observation, surveys, generalization). R e s u l t s . It was determined that the principles of people's representation and representative democracy are traditional for parliamentarism as a special system of public administration, on the basis of which representative bodies of state power have functioned on Ukrainian lands for many centuries, whose activity is characterized by electability and collegiality in making political and administrative decisions. Their varieties in different historical periods of the functioning and development of Ukraine (during the times of Kyivan Rus, the Lithuanian-Russian State, the Commonwealth of Nations, the Moscow State, the Cossack Republic, the Hetmanship as part of the Russian Empire, the Ukrainian People's Republic, the Ukrainian SSR, the Ukrainian SSR, and in modern Ukraine) and it was found that the majority of Ukrainians perceive them as a public value characterized by a higher level of legitimacy. It is noted that a special role among other representative bodies of state power is played by Councils, which are a custom (tradition) and passed from generation to generation, for which the Ukrainian people have been fighting fiercely against various interventionists at all times and now. The essence of the concept of "parliamentarism" and its structural elements, such as: institutions of the state (political and social) and institutions of democracy (election, publicity, equality before the law, distribution of power); considered the dual nature of the parliament as a state institution and an institution of democracy, which is a representative body of state power, has its own structure, forms, methods, management technologies and is responsible for creating an effective mechanism of interaction with internal structural elements and civil society. It is substantiated that in the conditions of global changes associated with the environmental crisis, the Covid-19 pandemic, a full-scale war with the Russian Federation, in Ukrainian society it is important to form a system of values in public administration, based on political and managerial ethical leadership, political responsibility, innovative activity. C o n c l u s i o n s .
