This paper presents a new method for identifying industry clusters. It draws on network analysis theory and relies on regional input-output tables as the information source. The methodology can be divided into two main blocks, data reduction and network partitioning. Data reduction starts by representing industries and products/services flows as a directed graph, where the links are represented as arrows indicating the flows directions. Based on several assumptions about how industries are related into a supply chain, the initial graph is transformed into an undirected graph by deriving relative weights from products/services flows. The second reduction is formulated as a minimization problem, resulting in a minimum spanning tree (MST) for a subset of the initial graph edges. The final clusters are obtained through selective deletions of edges in the MST, such that, each cluster contains a core industry.
In this paper, we propose an algorithm, RI-Maps, that combines fractal theory, stochastic calculus and computational geometry for simulating realistic irregular lattices with a predefined number of polygons.
The dropout rate among Spanish university students is very high compared to the European mean, creating a pressing need for the introduction of policies and programmes aimed at increasing rates of persistence.
