The Index of Industrial Production (IIP) is an important indicator of economic performance and its main purpose is to provide a measure of the short-term changes in the volume of industrial production over a given period of time. It can be used to identify the turning points in economic development at an early stage. Monthly IIP will be released quarterly with a time lag of 63 days. The base year for the IIP compiled by DCS is 2015. IIP value of difference base years cannot be compared.
