Can I get some help from anyone to understand what the IMPLAN local use ratio/regional supply coefficient is? The documentation says "The RSC, also known as the Local Use Ratio, indicates the proportion of local net supply of a commodity that goes to meet local demands. It is calculated by dividing Local Use of Local Supply by Local Net Commodity Supply. Local Net Commodity Supply is the amount of total local commodity supply that is used domestically (i.e., total local commodity supply less foreign exports)." I understand the local net commodity supply part of the definition (local output minus exports). But what is the "local use of local supply?" Is it not the same as the local supply less the exports? Or does the model assume the local supply is not equal to the sum of the local use and the exports?
