This volume represents the second in a series of IIASA conference proceedings dealing with case studies of large-scale regional development programs. The Bratsk-Ilimsk Territorial Production Complex (BITPC) is an example of how large-scale regional development programs are integrated into the system of national economic planning in the Soviet Union. The BITPC is the first of the major territorial production complexes in the Soviet Union, and the experience gained there is being used for the development of similar programs. The presentations included were prepared by the Soviet scientists actively involved in developing the concept of TPCs. IIASA scientists prepared additional papers, based on the presentations, in order to stimulate discussion and to clarify some of the issues raised.
