The paper analyzes the structure of the state administration in the Republic of Croatia. It was established that the development of the state administration system in Croatia went through different phases. As part of the different stages of development, there was also a different structure of the state administration. It can be said that in different periods the organization was organized in different ways. Through the paper, it was determined that certain forms of organization in practice can prove to be inefficient, which is why there is a need to reorganize the state administration system. Major changes in the system occurred under the influence of the accession of the Republic of Croatia to the European Union, however, the development of the state administration system did not end there. Gradually, efforts were made to reduce centralization in state administration, as well as to rationalize the number of state administration bodies and employees. The latest structure of the state administration, which is the result of the Act on the State Administration System from 2019 and the Act on the Structure and Scope of State Administration Bodies from 2020, actually has the smallest number of bodies since the beginning of Croatian independence. The law provides various possibilities of internal organization and the establishment of special organizational units, as well as the entrustment of state administration tasks to local and regional self-government units. Although significant progress has been achieved in the state administration system from the beginning of the Croatian state until today, there is still room for improvement, especially in the form of human resources management. For this reason, the Public Administration Development Strategy for the period 2022-2027. points out the need to adopt measures that will improve the system of wages, motivation and rewards as well as training and education in the state sector.
