Influencing Factors of Total Factor Energy Efficiency in Bohai Rim RegBased on DEA-Tobit Model

Abstract

Bohai Rim region is an important economic development area and a large carbon emission area in China. It is of great significance to explore the total factor energy efficiency and its influencing factors for the low carbon transformation and high-quality development of the Bohai Rim region. Based on the total factor energy efficiency framework, the DDF-DEA model was used to calculate the total factor energy efficiency, and the internal and external differences of the total factor energy efficiency were further analyzed. The internal and external influencing factors were determined by ML index method and classical endogenous growth theory, and then the Tobit panel model was used to empirically analyze the action mechanism of all influencing factors of total factor energy efficiency in the Bohai Rim region. The results show that the pure technical efficiency, scale efficiency and technological progress among the internal influencing factors contribute to the improvement of energy efficiency in the Bohai Rim region. Industrial structure, industrial internal structure and ownership structure inhibit the improvement of energy efficiency. Energy consumption structure and energy endowment also have a negative impact on energy efficiency. Therefore, measures such as promoting technological progress, adjusting economic structure and optimizing energy structure will effectively improve total factor energy efficiency in the Bohai Rim region.
