Methodology for QIM

Quantum Index of Manufacturing (QIM) measures the changes in production of Large Scale Manufacturing Industries (LSMI) over time on monthly as well as cumulative basis. The weights presently used for the QIM were derived from the Census of Manufacturing Industries (CMI) 2005-2006. 112 items with total weight of 70.332% of value added are being used for computation of QIM. The production data is collected from Oil Companies Advisory Committee (OCAC), Ministry of Industries & Production and Provincial Bureaus of Statistics.

Weights have been derived at two stages, the weight at industry level have been derived on the basis of Gross Value Added (GVA) of Large Scale Manufacturing Industries (LSMI) at the basic prices. The total GVA for the LSMI is taken as 100 and percentage contribution of each industry has been considered as the weight of that industry. At the second stage, the weights have been derived at product level on the following lines:-

  1. In case, there was only one item to be selected from a manufacturing activity, the total weight of that activity has been assigned to the selected item.
  2. If more than one items have been selected from a manufacturing activity, then weights of the activity have been distributed among the selected items according to relative production value of the selected items in that activity.
