Methodological approaches to estimating the efficiency of functioning of clusters

The article presents an analysis of theoretical and methodological approaches to clusters, cluster initiatives and the composition of indicators reflecting the effectiveness of the functioning of cluster formations in the modern economy. The aim of the study is to determine the general requirements for the composition of indicators and highlight the key determinants, the assessment of which makes it possible to obtain a holistic view of the state of clusters and the external effects of their functioning. Particular attention is paid to the study of indicators reflecting the influence of cluster effects on the socio-economic development of the territory of their location. The need for further research in this area, taking into account the classification of indicators proposed in the article, has been proved.
