A Regional Purchase Coefficient (RPC) is the proportion of the total demand for a commodity by all users in the Study Area that is supplied by producers located within the Study Area. For example, if the RPC for the commodity fish is 0.8, then 80% of the demand by local fish processors, fish wholesalers, and other fish consumers are met by local fish producers. Conversely, 20% (1.0-RPC) of the demand for fish is satisfied by imports.
Average RPC is the proportion of local demand for the Commodity that is currently met by local production. It is “average” in the sense that there is just one RPC per Commodity, so all Industries and Institutions are assumed to purchase that Commodity locally at the same rate.
