Transportation sectors in many countries have been attempting to increase their competitiveness by enhancing their productivity, providing better quality services and reducing their costs. Some transportation operators such as shipping lines and airlines generate more traffic and revenue than their competitors even though they use the similar level of labor and capital. On the other hand, some operators use less labor and capital than their rivals to produce the similar level of traffic and revenue. Undoubtedly, efficient transport operation that consumes less inputs and produce more outputs seems to be a certified check for gaining competitive edge in the fierce transportation industry. In addition, contemporary transportation sectors are required to operate their facilities more environmentally friendly due to increasing awareness and concerns of their stakeholders arising from global warming and climate change issues. Therefore, more transport companies are investing in environmental facilities to respond to the needs and concerns of their stakeholders.
Numerous studies were conducted to analyze the sectors’ productivity, efficiency and competitiveness based on commercial goods and services that they produce. However, only a few empirical studies have been undertaken regarding the environmental efficiency of the sectors since most previous studies have not considered undesirable outputs that the industries generate, for instance, CO2 emissions. Therefore, it is important to revisit the efficiency from an environmental perspective. To fill the gap in the literature, the objective of this presentation is to show various economic and environmental efficiency studies applied to transportation sectors, which Professor Chang has conducted recently. He will present important issues, new methodologies to address the issues and major findings.
