<p>This paper analyses relationship between the growth rate of mining sector and growth rate of GSDP at disaggregate level in Odisha. Results from trend analysis show that secondary sector is the second most leading sector in the state. Exploring the relationship between growth rate of individual sectors and growth rate of GSDP, Granger causality test shows that the growth rate of neither sectors nor subsectors have unidirectional causality with the growth rate of GSDP. Furthermore, there is no such causality found between growth rate of mining sector and growth rate of GSDP though it has its strong base in Odisha. Rather the parametric influence of all the sub-sectors clubbed under the secondary sector is found to be statistically insignificant. Despite the statistical estimation, the 2014-15 Odisha economic survey report by Govt. of Odisha reveals the fact that it is the secondary sector that leads the economy contained with mining and quarrying as the major contributor. Hence, the secondary sector is the growth driver for Odisha economy. So far as the long and short run relationship is concerned, ARDL bound test, Error Correction Model (ECM) shows a long run associationship among all the sectors and sub sectors such as; mining and quarrying (MQ), manufacturing (M), electricity, gas and water supply (EGWS), construction (CON), secondary sector (SS) and GSDP.</p>
