Development of information base for calculations on environmental pollution using an input-output model

The article is devoted to the development of information base for input-output calculations on environmental pollution in the region. We have revealed the problem of poor accuracy of assessing the anthropogenic impact on the Baikal natural territory without taking into account the nature of the industry. It is substantiated the necessity of using the apparatus of input-output modeling to increase the level of detail and validity of calculations. We have analyzed the informational problems of compiling regional input-output tables. Formulas are given for calculating the multiplicative effects of changes in the volume of wastewater discharge into surface water bodies and emissions of pollutants into the atmosphere from stationary sources by type of business. It is shown the limited use of classical input-output model for assessing environmental pollution within the framework of business activity corresponding to the Russian Industry Classification System. We have substantiated the relevance of taking into account the environmental pollution by households within the input-output model of total expenditures.
