Japan experience: system analysis and modelling inter-industry relations

Abstract

The scheme of analysis and modelling inter-industry relations used by the Government of Japan in the planning and maintenance of economic proportions is considered. A scheme of the circulation of the Japanese economy has been prepared, coming out of the Input-Output table for 2015. On the basis of the input-output table of Japan (2015) it was prepared aggregated input-output tables of Japanese economy dimensions of 13 types of economic activity and 3 consolidated activities (primary, secondary, tertiary sectors). The Input-Output tables are prepared in a competitive-import version, which is the most common in Japan. On the basis of aggregated Input-Output Tables, the analysis of the development of sectors of Japan's economy during 1990-2015 was conducted. The classification of industries on the core ones, with direct influence as well as with inverse influence, etc. was carried out. Structural changes in GDP at final costs, production method and income categories are analyzed. A visual assessment of the volatility of the GDP structure was carried out. The factors of added value, import, impact are analyzed. The necessity of using aggregated input-output models to assess reproduction proportions, the state of the production system and its efficiency is substantiated. A promising direction of research and practical use is the use of the research schemes for studying and modelling the economy of Ukraine, for scientific and educational purposes, preparation of a competitive-import version of the input-output tables of Ukraine of different degrees of aggregation, conducting comparative researches of the development of economic systems, etc.
