This paper analyzes the industrial activities and their actual comparative advantages in Khuzestan province using two digits ISIC cods and DRC criterion for the period 1377-82 (1998-2003). The results show that international competitiveness of industrial activities has been improved since 1381, the time of implementation of exchange rate unification and relative economic liberalization policies in Iran.
This paper also suggests a simple decomposition of DRC measure to isolate the determinant elements of international competitiveness of some industrial activities under consideration. These elements are: (1) government intervention in economy, (2) factor cost, (3) factor proportions and (4) total factor productivity. The results imply that alleviation of the size of government interventions in economy has the most important role in improving the competitiveness of industrial activities in most cases.

Iran as a developing country possesses rich and extensive energy resources has an advantage in energy-intensive industries. In this research, Granger-causal relationship between economic growth in Iran and various energy carriers including oil products, electricity, natural gas and solid fuels are investigated using Toda and Yamamoto procedure for period 1967-2002.
The results reveal that there is a unidirectional Granger-causal relationship from electricity consumption and oil products consumption to economic growth. Likewise, there is a unidirectional Granger-causal relationship from economic growth to solid fuels consumption and natural gas consumption. Estimation of error correction models reveal that in the short run and long run, there is bidirectional Granger-causality between electricity consumption and economic growth. Likewise, in the long run, a unidirectional Granger-causality runs from economic growth to natural gas consumption. Therefore, in the cases that unidirectional Granger-causality runs from energy consumption to economic growth, energy conservation policies should be designed carefully in a way that utilization of such policies doesn't have diminishing effects on economic growth. Accordingly, we suggest a set of “optimal usage” and “efficient consumption” policies in economic sectors. In the cases that unidirectional Granger-causality runs from economic growth to energy consumption, energy conservation policies could be implemented without impeding economic growth.
