The main subject of this doctoral dissertation is the management of technological changes in the state administration bodies of the Republic of Croatia. The importance of this issue stems from the fact that nowadays changes in state administration, as well as in the whole society, are strongly driven by technological advances. In state administration bodies, technological changes are closely connected to the process of computerisation of business and e-government development. Therefore, the effective management of technological change is one of the fundamental preconditions for building a modern state administration. In order to verify the hypothesis, a survey was conducted on a sample of employees in the central bodies of the state administration of the Republic of Croatia. From the results it appears that the staff in the state administration bodies have satisfactory IT equipment at their disposal but they are mostly used to perform simple tasks. The analysis further indicated that although employees rate their general IT literacy with relatively high marks, their knowledge and skills in using information and communication technologies, especially in the case of certain groups, ought to be improved. Based on the employee responses, it was concluded that they are aware of the benefits that technological changes can bring and that they generally consider them to be justified. However, the technological changes that have occurred in their institutions, as well as the technological change management, are not evaluated sufficiently positively. The results also confirmed that there are no significant differences in the employees’ ratings with respect to gender, age, degree of education and position in managerial structure. Three factors were determined within the factor analysis. Statistical tests revealed that the hypothesis stating that the analysed groups of employees significantly differ from each other with regard to the determined factors can only be partially accepted. In addition, it has been established that material incentives are not the most important factor in accepting technological change and that the employees are somewhat satisfied with the e-government. Therefore, there is no doubt that the management of technological changes in the state administration bodies needs to be improved and the process of computerisation of their business should be intensified.
