Forward linkages capture how the increased output of a sector provides additional inputs to other sectors, enabling them to expand production.
Arguments
- output_coefficient_matrix
An output coefficient matrix created with
output_coefficient_matrix_create().- digits
Integer. Number of decimals for rounding. Defaults to
NULL(no rounding).
Value
A data.frame with two columns:
The metadata column from the input matrix (sector/product names)
forward_linkages: the forward linkage indicator values
Details
Defined as the row sums of the Ghosh inverse, in line with the Eurostat Manual of Supply, Use and Input-Output Tables (pp. 506–507) and the United Nations Handbook on Supply and Use Tables and Input-Output Tables with Extensions and Applications (p. 637).
