Industry "Fishing and Aquaculture" as economic unit in the Baltic states and Finland

The research is devoted to the industry “Fishing and aquaculture” as an economic unit in Estonia, Finland, Latvia, Lithuania. With help of the input-output mathematical model, mathematical analysis, and adequate software we carry out the economical and technological analysis of the industry “Fishing and aquaculture”. The analysis is provided in the comparative aspect (comparing Estonia, Finland, Latvia, Lithuania) and in the dynamic aspect (using statistical information for 15 years). The statistical information in current research is the National Input-Output Tables for the 2000-2014 available via the World Input-Output Database. The original modification of the classical input-output model created by Jaunzems (2017), especially for World Input-Output Database's information structure, allows us to calculate and to interpret line of economical and technological indicators: technological interindustry coefficients, Leontief inverse, monetary allocation coefficients, Ghosh inverse. All economical and technological interpretations of indicators are based on the mathematical connections resulted from the input-output model. According to the International Standard Industrial Classification of All Economic Activities, agriculture is divided into three industries “Crop and animal production, hunting and related service activities”, “Forestry and logging”, “Fishing and aquaculture”. The authors have already provided the comparative dynamic analysis of the industries' “Crop and animal production, hunting and related service activities”, “Forestry and logging” economies (ERDEV: 2018, 2019). The systemized and founded conclusions about whole agriculture will be presented to the Agriculture Ministry of Latvia for the more detailed analysis and proper actions elaboration.
