Many authors stress the importance of relationships between sectors for the economic growth. Therefore the concept of linkage appears in the definition of two of the most traditional concepts in the input-output analysis: the “key sector” and cluster. In this paper, key products and...

The paper introduces an alternative method to determine "sensitivity' within an input-output-context and makes the most sensitive connections visible in an overall graph. The method called ECA (Elasticity Coefficient Analysis) tries—like the Important Coefficient Analysis (ICA)—to derive...

A wide range of approaches are available for classifying coefficients according to their importance to an economy. The 'tolerable limits' approach is one that has been extensively written about. Nevertheless, it seems unsuitable for assessing the overall importance of a coefficient to an...

The input-output structural analysis is a valuable tool when designing economic policies since it allows us to know which are the most important linkages and sectors of an economic system. The coefficients' sensitivity analysis is one of the major approaches of the structural analysis. With it...

The Input-Output model has made extensive use of graph and network theory, methods and conclusions, in order to carry out structural analysis; such extensions have yielded powerful insights on the relationships existing between industries in an economic system. It is customary in the field to...

Network analysis in the input-output field is an ongoing and interesting area of research which has seen a rise in contributions in recent years. In the input-output field, studies based on graph and network theory have been developed only about topological measures used descriptively. Modelling...

The ‘cluster theory’ has become one of the main concepts promoting regional competitiveness, innovation, and growth. As most studies focus on measures of concentration of one industrial branch in order to identify regional clusters, the appropriate analysis of specific vertical relations...
