This visualization shows the structure of the Eora MRIO table.
Each pixel represents the value of sales from companies in some sector A to companies in some setor B. Colors represent the total value of sales, with greens representing a small volume of tranactions and oranges and reds representing larger volumes.
The origin country/sectors are read down along the lefthand side, and the destination country+sectors are read horizontally across the top. Consider two coordinates:
Y = [coordinate of country R / sector A]
X = [coordinate of country S / sector B]
The MRIO matrix element at coordinate (
Y) will contain the sum of all sales originating from companies in sector RA with the destiantion of companies in sector SB.
Y in an IO/MRIO table can be read as a sales mix showing which
other sectors buy
Y's ouput. Each column
X documents the
production recipie showing which goods
X buys from each other in order to make their outputs.
The domestic IO tables for each country are visible as red-orange blocks along the main diagonal. Countries with lower-resolution IO tables with fewer sectors are smaller, and countries with highly detailed IO tables appear larger. A prominent diagonal line is visible in many blocks of the MRIO. This reflects the fact that there are large in-sector flows, with companies in a sector selling to other companies in a sector. The green-yellow blocks are trade blocks which record flows between sectors in different countries. Each block is labeled with the three-letter code for the origin country and destination country. For example the Australian domestic flows block would be labeled "Aus,Aus" and the trade block of sectors from Australia to Austria is labeled "Aus,Aut".
