Melnychuk N.Yu. SCIENTIFIC APPROACH TO ASSESSING THE EFFECTIVE MANAGEMENT OF BUDGETARY FUNDSPurpose. The aim of the study theoretical foundations of public administration and develop a scientific approach on this basis to assessing the effective management of the budgetary funds in accordance with international rankings.Methodology of research. The results of the study are based on the use of abstract and logical (when examining existing approaches to public administration assessment) and statistical analysis (when calculating the indicator of the effective management of budget funds of Ukraine in accordance with international ratings). The theoretical and methodological basis of the study is the key provisions, principles and methods of modern economic theory, finance and economics.Findings. It is substantiated that successful functioning of the budgetary system is possible provided that the real state of management of the formation and use of budgetary funds is monitored, and the effectiveness of managerial making decisions in the budgetary process is evaluated. It is proved that the current state of economic development of Ukraine is characterized by instability, stagnation, and lack of effective state management of budgetary funds. Global approaches to assessing public administration performance based on GRICS and the Budget Transparency Index are explored. This made it possible to propose a scientific and methodological approach to assessing the effective management of the budgetary funds.Originality. The scientific and methodological approach to assessing the effectiveness of the budgetary funds management is proposed, a feature of which is the introduction of the calculation of an appropriate indicator of efficiency with the separation of direct (transparency in the budget sphere, citizen participation in the budget process, budget surveillance) and indirect (political stability, government efficiency, rule of law, control over corruption) factors and levels (high, relatively high, medium, low and critical) of efficiency. This approach enabled both to analyse practically the efficiency of budgetary funds management in Ukraine during 2008-2017, and determine its position among other countries of the world for 2017.Practical value. The developed scientific approach enriches the theory and practice of the management process of budgetary funds as a component of state regulation system and can be applied in the activity of legislative and executive bodies of state power and bodies of local self-government in the development and making management decisions in budgetary area.Key words: budget; public administration; budgetary funds; efficiency of management; public debt.
