This document outlines a proposed study to model regional economic growth using a multi-agent system (MAS) approach integrated with geographical information systems (GIS). The study aims to analyze complexity in regional growth, develop a model of growth patterns, and identify how economic factors contribute to growth. It will examine firm demography and apply GIS and MAS technologies to the urban planning context of the Klang Valley region in Malaysia. Literature reviews on related topics have begun and data requirements have been identified. The expected findings are to create a growth model to help understand land use patterns and aid decision making.
