This study has analysed whether the high growth rate in telecommunications service sector has a favourable impact on productivity growth rates of the telecommunications equipment industry in India. In this study, the total and partial factor productivity growth rates are measured for the telecommunications equipment industry during 1999-2016. The translog index is used to estimate the total factor productivity (TFP) growth rate of this industry in a five input KLEMS - framework. The period of study is divided into two sub-periods, i.e., 1999-2007 (sub-period I) and 2008-2016 (sub-period II). The annual growth rate of total factor productivity is estimated to be 3.56% in sub-period I and 2.22% in sub-period II. It has been observed that the growth rate of gross value added (GVA) has decelerated between two sub-periods as the industry has become more import-centric due to implementation of the information technology agreement.
