TerminologyΒΆ
So far, there is no consistent terminology for MRIO systems and parameters in the scientific community. For pymrio, the following variable names (= attributes of the IOSystem and Extensions) are used (the alias columns are other names and abbreviations often found in the literature):
variable name | formal name | alias variable names | alias formal names | description |
---|---|---|---|---|
Z | transaction matrix | T | flow matrix | transactions matrix, inter industry flows |
A | A matrix | inter-industry coefficients (direct requirements matrix) | ||
L | leontief inverse | B | leontief inverse (total requirements matrix) (multi regional approach) | |
Y | final demand matrix | H, y | final demand matrix (sectors x region/countries and final demand categories) | |
x | gross output | q | industry output | total output, defined as column vector |
F | factor production | extensions, stressors | Factors of productions: extensions plus value added block | |
FY | factor production final demand | yF | thats kind of a weird name - maybe we can find a better: basically that are the extensions (e.g. emissions) of the final demand | |
S | factor production coefficients | D | stressor coefficients | |
SY | factor production coefficients final demand | DY, yD | ||
D_cba | consumption based accounts | fp, con | footprints, consumption footprints | footprint of consumption, further specification with reg (per region) or cap (per capita) possible |
D_pba | production based accouts | terr | territorial accoutns | territorial or domestic accounts, further specification with reg (per region) or cap (per capita) possible |
D_imp | import accounts | imp | import accounts, further specification with reg (per region) or cap (per capita) possible | |
D_exp | export accounts | exp | export accounts, further specification with reg (per region) or cap (per capita) possible | |
M | multipliers | m | ||
pxp | iosystem products x products | mxm | ||
ixi | iosystem industries x industries | nxn |
