A new procedure is presented for estimating input-output tables with limited survey data. Its significance lies in two areas: it demonstrates the efficacy of adjusting biproportionally the Leontief inverse rather than the matrix of technical coefficients and it shows the potential of utilizing independently gathered, less expensive, employment data in the column constraint. This procedure is tested by use of Washington input-output tables; the results compare favorably with conventional RAS adjustments.

The Cross

In this paper we deal with extractions of one sector (region) or a number of sectors (regions) from an (interregional) input—output system. When a certain number of sectors is taken out of the input—output matrix one obtains a cross. It is shown that the Leontief-inverse for a cross can be decomposed into the product of three matrices, OUT*INTRA*IN, where INTRA represents all intracross economic interactions, IN represents all effects from the rest of economy upon the cross, and OUT represents all effects from the cross upon the rest of economy. Furthermore, we present a general scheme of additive as well as multiplicative decompositions of the Leontief-inverse, reflecting the hierarchical decomposition of the matrix of input coefficients into the sum of crosses. These decompositions provide us with the means to find new insights into efficient aggregation, importance of regions, and issues of industrial complexes in inter alia input—output analysis.

User Activities

This work aims to analyze the tertiarisation process of two neighbouring countries, Spain and Portugal, during the period 1995-2005. In this regard we pretend to find out if there are differences between the two productive systems as for the use of tertiary inputs or it is possible to talk about the “Iberian productive system.” It is also analyzed if different activities employ the same amount of tertiary inputs within their productive processes. These findings could be a key to explain the tertiarisation processes in both countries. The methodology that enables to quantify the level  of tertiarisation of economies is based on the input-output analysis. The impact of services on user activities is appreciated by means of a series of effects that can be obtained through the technical coefficients and the Leontief inverse matrix.

Current Concerns

According to the current concerns about social welfare and environmental protection, integrated in a model assimilated to intrabusiness relations, our research started from the analysis of the initial model SAM, which will be transformed in order to develop the SAMI model under six research objectives. The need of improving SAM matrix started to connect it directly to the regional economic systems and continued to a new approach on Input-Output Analysis. Nowadays, SAM describes the intraregional connections between regional economic actors using the role of different income categories. Moreover, SAM can quantify different regional multipliers. All deficiencies previously identified in connection to SAM model have been reviewed and resolved within the proposed SAMI model by the authors of this paper. The purpose of this research is the launch of an absolutely new mathematical model (SAMI) and its practical testing at regional level. This model is able to systematize the links between the local and regional businesses, under the matrix (SAMI) flow, for all kinds of companies and to assist the regional decision, as well. Czamanski was not able to escape from the input-output prison’s approach. This is why he continued to use the linear interdependencies between the industries, economic sectors and economic actors. The income is able only to approximate the individuals and other economic actors’ welfare. If the increase in the average and aggregate income is doubled by an unfair distribution of income in two countries which have the same average income, the effects on welfare vary a lot. A relatively similar effect comes from the government policy differences in income distribution and redistribution.

The purpose of the study was to determine the problem of control of a dynamic system of higher dimension. Relying on Leontev input-output balance, we formalized the dynamic system and synthesized its control. Within the research, we developed a mathematical model that combines different working objects that consume and release various resources. The value of the penalty for all nodes and objects is introduced into the matrix representation of the problem, taking into account various options for their interaction, i.e., the observation problem. A matrix representation of the planning task at each working object is formed. For the formed system, a control loop is created; the influencing parameters of the external environment are indicated. We calculated the system operational mode, taking into account the interaction of the nodes of objects with each other when the parameters of the external environment influence them. Findings of research show that in achieving a complex result, the system is inefficient without optimal planning and accounting for the matrix of penalties for the interaction of nodes and objects of the dynamic system with each other. In a specific example, for a dynamic system with a dimension of 4.8 million parameters, we estimated the control taking into account the penalty matrix, which made it possible to increase the inflow of additional resources from the outside by 2.4 times from 130 billion conv. units up to 310 conv. units in 5 years. Taking into account the maximum optimization of control in the nodes, an increase of 3.66 times in the inflow of additional resources was ensured --- from 200.46 to 726.62 billion rubles

There are different definitions of complexity in many areas. For a heavy-payload manipulator, the kinematic coupling degree problem, which has much influence on its control and reliability, is very important. This paper proposes a definition of complexity to measure the kinematic coupling degree of a manipulator. After the manipulator's desired output motions in the workshop are obtained, the matrix relating the velocities of actuated joints to the velocities of all basic output motions is calculated. Based on the preceding matrix, the definition of complexity is presented. To illustrate the methods introduced in this paper, four types of heavy-payload forging manipulators (FMs) are analysed, and the type of FM with the smallest complexity is chosen as our prototype.

Concentrating on consuming coefficient, partition coefficient, and Leontief inverse matrix, relevant concepts and algorithms are developed for estimating the impact of meteorological services including the associated (indirect, complete) economic effect. Subsequently, quantitative estimations are particularly obtained for the meteorological services in Jiangxi province by utilizing the input-output method. It is found that the economic effects are noticeably rescued by the preventive strategies developed from both the meteorological information and internal relevance (interdependency) in the industrial economic system. Another finding is that the ratio range of input in the complete economic effect on meteorological services is about 1 : 108.27–1 : 183.06, remarkably different from a previous estimation based on the Delphi method (1 : 30–1 : 51). Particularly, economic effects of meteorological services are higher for nontraditional users of manufacturing, wholesale and retail trades, services sector, tourism and culture, and art and lower for traditional users of agriculture, forestry, livestock, fishery, and construction industries.

When formulating economic development strategies, the environment and society must be considered to preserve well-being. This paper proposes a comparative sustainability assessment method using environmentally extended input-output analysis and multi-criteria decision aid. Using symmetric input-output tables and sectoral CO2 emissions and employment data for six countries, linkage coefficients are calculated for 163 sectors in each country. Multi-criteria decision aid tool, ELECTRE III, is used to derive outranking relationships among each country’s sectors using these coefficients as criteria, resulting in a hierarchy of sectors ordered by sustainability. Sectors that frequently appear at the top of the six hierarchies included education, health care, construction, and financial intermediation. China’s results differ significantly because of its concentration of economic activity on the primary/secondary sectors. The results can enable identification of key intervention pathways along which sustainable development could be stimulated. Country-specific recommendations and reflections on economic and sustainability policy initiatives are discussed.
