| Abstract: | Based on the discussion of the basic principles of RAS method , modified RAS method and lagrange undetermined coefficient method about calculating direct consumption coefficient, the article analyzes comparatively advantages and disadvantages of three methods motioned above by combining the input-output tables in 2002 and 2007 and extensive table in 2005 of Chongqing. The optimum method will be selected to provide the basis for the amendment and forecast of direct consumption coefficient in the future. |
