In this document, we study the industrial district of Jepara, Indonesia. It is specialised in furniture production, for Indonesian consumption as well as for worldwide exports. We summarize the main features of the dynamics of the firms involved in the Jepara industrial complex with a quantitative analysis of flows among them, and between them and markets elsewhere. A specific method of spatial analysis was designed, and merged with existing methods for the analysis of forest production networks and social networks. This method allows to take into account and to accurately assess the number of very small workshops that cannot be evaluated by classical methods. We demonstrate that both the official statistics and the existing literature about Jepara considerably underestimate the extent of the wood industry and its activities. We present the results through synthesis maps. A total of 15 271 units of production have been identified, employing approximately 170 000 workers in Jepara. The activity generates considerable revenue: between 11 900 and 12 300 billion Rp/year of added value (about 1 billion euros/year), that is to say between 70 and 78 million Rp/worker/year. The district of Jepara consumes between 1.5 and 2.2 million m3/year of roundwood, and in other words, we found that the use of around 9 m3 of roundwood sustains one full-time employee for a year. The organisation of the production is typical of an industrial district, featuring a high level of intertwined relationships and subcontracting among highly specialised production units and a prevalence of small and very small units in various steps of the production rather than bigger, integrated units.
