Today, strategic planning is widely used in the contemporary Russian public administration practices for regional socio-economic development. Since 2005, the regions have started to develop their own economic strategies, most of which were adopted before 2020, so it is not too soon to sum up the implementation results of regional strategies for this period, i.e. assessment of target values of socio-economic indicators, implementation of socio-economic projects, completion of the construction projects provided for in the strategic planning documents. The paper analyzes the achievement of certain targets indicators in the development strategies of the Republic of Tuva and the Novosibirsk Region. Currently, the mechanism to monitor the implementation of strategic documents is not well developed. The development of such a monitoring procedure would make it possible to turn the strategy from a “goal setting document” into an effective tool for the public and non-government organizations to evaluate the efforts of regional executive bodies towards promoting socio-economic development of the region. The development of performance assessment methodologies is complicated by the impossibility to apply a uniform strategic methodology because the strategies are different for each region.
