Regional Market Share
The trade share tells us how important a particular trade partner is in terms of the overall trade profile of an economy.
In the case of intra-regional trade 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. The trade share is the total of exports from source to destination and imports from destination to source,
expressed as percentage of the source region's total exports plus imports.
The trade share is the percentage of the region under study’s trade (imports plus exports) with another region of interest, in the total trade of the region under study.
Range of values:Takes a value between 0 and 100 per cent, with higher values indicating greater importance of selected trading partner.
