KRUMME G. Comments on interregional subcontracting patterns and bilateral feedbacks
The development of flow analysis, particularly interregional repercussion analysis, is severely handicapped by the dearth of data. For a number of years, NASA and the Pentagon have released data on the distribution of prime contractors in the United States. More recently, NASA also made accessible information on subcontract: and "sub-subcontracts." The paper suggests a way to utilize these data for capturing simple, two-region feedback effects of subcontract: which 'leak" from the prime -contracting region. The aggregate bilateral feed-back coefficient for any one region is an aggregate expression of three component-coefficients which isolate those parts of first-round subcontracts awarded to individual other regions, those parts resubco ntracted in the receiving regions, and, finally, those portions "returning" to the initial subcontracting region. A simplified and incomplete matrix of interstate subcontracting coefficients suggests the possibility of hierarchical characteristics in this interregional pattern with California as the dominant region
