The regional production technology is described in the input coefficient of the regional input-output system, and it is possible to grasp regional production technology by decomposing the input coefficient. In this study, we propose a new grasp method of the regional production technology by using the information incorporated in the input coefficient. This method is derived from decomposing the structure of input coefficient. Then, we define the difference in the patterns of decomposed input coefficient between the whole country and the region as regional characteristic of the production technology structure. The second, we propose an analytical method of regional input-output structure by using a new grasp method of the regional production technology. This analytical method is effective in analysing the regional characteristic of input-output structure.
