Variables during the study and the source of the data, relying on four aspects of change and deformation processing, Sichuan Province2009input-output table is the basic data table, input-output tables, the use of mathematical software matlab industry also calculated42Data obtained their contact with each other, with the direct consumption coefficient table and the coefficient table to reflect the total consumption, and resulting Leontief matrices and Leontief inverse matrix.Conclusion of the previous model based on the results of data analysis, the development of Sichuan Province, for reasonable wholesale and retail industry to provide theoretical support for the policy, while exploring Sichuan wholesale and retail trade and other specific industries which have a close relationship and the inter-of to what extent.
