The wood industry in the district of Jepara is not uniformly spatially distributed, but is clustered at different locations and densities, each of which had to be characterised and quantified. At the outset, the position of all industrial or commercial enterprises and workshops that use,process, display, or store wood material, including the smallest family businesses located on even the smallest streets and side roads. Each unit was categorised based on the main economic activity (workshop, showroom, log park, sawmill,warehouse, and ironmonger), and the and the size of the unit (small, medium, and large).

Industry in Jepara comprises a complex network of relationships and flexible subcontracting.

The enterprises of Jepara can be categorized into three groups.

• The first consists of integrated enterprises, which produce essentially finished or prefinished products from an input of unprocessed roundwood.
• The second group comprises those enterprises (log parks and sawmills)that specialise in initial processing of the raw material to produce simple sawn timber for the third group.
  
• The third group is made up of workshops in which the input comprises sawn timber and various components, pieces, and sets of products at different stages of manufacture, which are then assembled into a finished product.
