Complementarity
The complementarity index is a type of overlap index. It measures the degree to which the export pattern of one country matches the import
pattern of another. A high degree of complementarity is assumed to indicate more favorable prospects for a successful trade arrangement. Changes over time
may tell us whether the trade profiles are becoming more or less compatible.
Definition:
The sum of the absolute value of the difference between the import category shares
and the export shares of the countries under study, divided by two. The index is converted to
percentage form.
Range of values:
Takes a value between 0 and 100, with zero indicating no overlap and 100
indicating a perfect match in the import/export pattern.
For further note on this indicator, including an example and formula, see the relevant section of Trade Statistics in Policymaking: A Handbook of Commonly Used Trade Indices and Indicators.
