Formation of the information base for analytical calculations with the use of a regional input-output model

The article substantiates the need to form an information base for analytical calculations of regional socio-economic development in the sectoral context. As a methodological tool the method of cross-sectoral analysis was proposed. We made a comparative analysis of the economic activities in the primary, secondary and tertiary sectors of the economy of the Republic of Buryatia and harmonization of their list in input-output tables with the forecast of the regional socio-economic development of the Republic of Buryatia for 2018-2020. An algorithm for aggregation of input-output tables in the Republic of Buryatia for analytical calculations is developed. The input-output table obtained after aggregation has a dimension of 44x44. We calculated the sectoral multipliers of gross output, the largest values of multipliers were observed in “Production, Transmission and Distribution of Electricity, Gas, Steam and Water” - 2.6, “Production of Beverages and Food” - 2.4, “Extraction of Other Minerals” - 2.3.
