Two general relations among four different input and output requirements matrices and the decomposition by factors in the Leontief inverse were proposed by the author(1998, 2005). Furthermore, the inverse matrix , which describes the relation between the output requirements for final demand and the output requirements for output, and the matrix , which indicates the relation between the final demand and the final output , were derived by Gim(2005).From the research results above, the study objectives of this paper can be summarized as follows. (1) We perform a comparative analysis between the input-output and output-output models. (2) We build a new final demand-final output model and present the interindustry characteristics between the variables final demand and final output. (3) We empirically analyze the interdependence between final demand, total output, and final output based on the 2000 Input-Output Tables of Korea(Bank of Korea, 2003). Therefore, we hope that the use of three different models, which are entirely different on the impact effects and but there are mutually complementary, would permit us more flexibility in choosing the methods for handling economic issues and modeling real-world applications.
