It is indicated that the proper functioning of local executive power, the creation of an optimal system of local executive power bodies should ensure effective influence on the development of each region, especially the cross-border region. It is generally accepted that local bodies of executive power implement the functions of the state, which are close to the population. In Ukraine, a new people-centered model of activity of public administration subjects is being formed. The article examines the process of formation of administrative authorities and management in Subcarpathian Rus (Transcarpathia) during the first half of the 20s of the 20th century. It was established that the process of forming the structure of state administration in Subcarpathia began already at the beginning of 1919, and in the summer of the same year, several projects of the organization of government in the region were already developed in Prague. On the basis of the General Statute, the model of relations within the local government between the Directory, the administrator and the military leadership during 1919-1920 was analyzed. The formation of abstract departments at the Civil Administration, which was headed by an administrator, is briefly described. The importance of the changes introduced by the government decree No. 356/1920 «On amending the General Statute of Subcarpathian Rus» was revealed, according to which the functions and powers were radically redistributed in favor of the bodies that represented the central government in the region. The theory of the creation of two branches of administrative management in relation to the competence of the Civil Administration of Subcarpathian Rus is presented: autonomous institutions and institutions of the state. The description of the gubernatorial council as an advisory body under the governor is provided. It was noted that the new General Statute, in terms of the norms governing the activities of the vice-governor and the gubernatorial council, went beyond the Constitution of the Czechoslovak Republic. It is proved that the administrative reorganization in Czechoslovakia in 1925 and especially in 1927 only distanced Subcarpathian Rus from real autonomy, since the process of further centralization and unification of power and administration took place throughout the territory of the republic. Appropriate conclusions have been drawn regarding the retention and gradual incorporation (integration) of the region into the all-Czechoslovak legal system.
