Balance Method, a method of linking and coordinating the processes of socialist reproduction to ensure the balanced and dynamic development of all branches and subdivisions of the economy, and the improvement of the inter- and intra-branch proportions. The balance method is used extensively in planning and statistics. Its scientific and theoretical basis is the Marxist-Leninist theory of socialist reproduction. Economic balances are drawn on the basis of the principle of equality of the volume of resources and their use, and the principle of the correspondence between the indicators of both and the calculation of the creation of reserves. A variety of economic balances are employed to define the quantitative relations between the production of the means of production and consumer goods, the exchange between these two departments (and within each of them), between the consumption and accumulation of the national income, and between the capital construction plan and material and machinery resources, labour and financial resources, the capacity of the construction and installation organisations, etc. The balances of material and labour resources, production capacities, and the financial balance and balance of money incomes and expenditures of the population are a constituent part of the state’s five-year plan for the country’s economic and social development. Mathematical methods and computer technology are widely used in balance calculations. The inter-branch balances of production and distribution of the product, of labour expenditure, and of fixed assets are examples: their indicators reflect a more accurate and detailed characterisation of the most important processes in reproduction. The balance method is used for economic calculations on the scale of the entire economy, and for branches and regions. It links figures general for the entire economy with indicators of the distribution and use of productive forces by branches and territories. The compilation of the balance of the national economy is the highest level of balance calculations.
