Abstract
The compilation of several social accounting matrices for Indonesia has enabled the analysis of some important aspects of the structure of the Indonesian economy. In the present paper, the analysis that has been conducted with structural path methods will be enhanced through the identification of a block structure for the technique. This block structural path analysis is offered as a complement to—not a replacement for—the traditional applications of this method. A new form of triple decomposition of the social accounting matrix inverse is offered to assist in identifying important changes in the structure of the Indonesian economy for 1975, 1980 and 1985.
