iotables (version 0.4.7)

backward_linkages: Backward linkages

Description

Indicate the interconnection of a particular sector to other sectors from which it purchases inputs (demand side). When a sector increases its output, it will increase the total (intermediate) demand on all other sectors, which is measured by backward linkages.

Usage

backward_linkages(Im)

Arguments

Im

A Leontieff inverse matrix created by the leontieff_inverse_create function.

Value

The vector of industry (product) backward linkages in a wide data.frame class, following the column names of the Leontieff inverse matrix.

Details

Backward linkages as defined by the Eurostat Manual of Supply, Use and Input-Output Tables (see p506-507.)

Examples

# NOT RUN {
de_coeff <- input_coefficient_matrix_create( iotable_get(), 
                                             digits = 4 )
I <- leontieff_inverse_create (de_coeff)
backward_linkages (I)
# }
