Regional Market Share
The export share tells us how important a particular export partner is in terms of the overall export profile of an economy. In
the case of intra-regional export shares, increases in the value over time are sometimes interpreted as an indicator of the significance of
a regional trading bloc if one exists, or as a measure of potential if one is proposed. It is obtained as the percentage share of the source region's
total exports that are bought by the destination region. It can be calculated on the basis of total trade, or an individual commodity.
The export share is the percentage of exports from the region under study (the source) to the region of interest (the destination) in the total exports of the source region.
