Energy efficiency in vietnamese enterprises: The predominance of gas consumers
Abstract
Energy inefficiency is a serious issue in the Vietnamese industry, which is the sector consuming the most energy in Vietnam. This article adopts stochastic frontier analysis (SFA) to evaluate the factors that influence the energy inefficiency in Vietnamese enterprises. Under the evaluation for the tile industry, the empirical results indicate that there are many factors having significant impacts on energy inefficiency, including fuel type, ownership structure, size of firms, labour quality, energy price and import activities. Related to the fuel type indicator, this article discovers that the level of energy inefficiency in firms using gases is 1.258 times lower than in firms using other fuels. That is the obvious evidence for the better performance of gas consumers in term of energy efficiency.
