Dr. Hashim Al-Ali, Mukhallad Omari, Orouba AlSabbagh: The Jordanian sectoral linkages, leading
sectors and import leakages

Or using another methodological setting, this as:

v j = n * b j / ( ∑ b j ) ……… (4)

j

With n as the number of the sectors in the economy, and (*) is sign for multiplication.

While for the forward linkage indices (u i ), the calculation systems are:

∑ r ij ∑ ∑ r ij

j i j

u i = ------ / --------------- ………..(5)

n n

Or in another way it can be calculated as:

u i = n * c i / (∑c i ) …………. (6)

i

Those sectors with a higher than average backward linkage index (i.e. v j > 1) generate an

above average response in the other sectors of the economy, and the status for the relative

performance of different industries is shown in table (1). These are driven from both; domestic

T
I/O coefficient matrix (A) and total I/O coefficient Matrix (A ).
A higher than average forward linkage index means that these sectors display above

average dependence on the demand from other sector. By increasing the output of such sectors it

is hoped that the industries which purchase them will be encouraged by the greater availability of

supplies to increase their own output.

The Five main sectors are construction, air Transport, electricity, iron and steel and

telecommunications, all of which are major inputs to several other sectors and industries. still,
