Sectoral Analysis of Energy Productivity Convergence: Empirical Evidence from Asian Countries

This study examines the convergence of energy productivity at the sectoral level across 35 Asian countries from 1991 to 2011 by using the spatial panel data approach. The results reveal that mixed evidence of convergence process in the sectoral energy productivity for these 35 Asian countries. We found beta-convergence process exists in energy productivity in the construction, manufacturing, mining; manufacturing and utilities, transport; storage and communications, and wholesale; retail trade; restaurants and hotels sectors. While there is no evidence of energy productivity convergence in the agriculture; hunting; forestry and fishing sector over the study period. Moreover, the spatial spillover effect has a positive impact on the sectoral energy productivity growth in 35 Asian countries.
