Existing studies have focused on the negative impact of inefficient resource allocation on energy performance in China, but neglected to explore the underlying reason for this phenomenon from the perspective of market segmentation. To fill this research gap, the epsilon-based measure model is used to estimate energy efficiency, and the measurement method of market segmentation is improved in this paper. On the basis of a theoretical hypothesis, we use fractional regression models to conduct empirical research. The results show that market segmentation has a significant negative effect on China’s energy efficiency. Additionally, this inhibitory effect is robust but heterogeneous. The impact mechanism test indicates that energy price distortion, enterprise technology innovation, and industrial ag)glomeration are three intermediate influence channels. Based on these analyses, we suggest that China should accelerate market-oriented reform and eliminate market segmentation in pursuit of energy-saving and emission-abating goals.

The energy rebound effect is a potential threat to energy-saving targets based on energy efficiency improvements. This paper employs a stochastic energy demand frontier model to analyze the energy demand and rebound effect in China's urban residential sector. Using a panel data set of 30 Chinese provincial-level regions over the period 2001-2014, for the first time, we investigate the degrees and determinants of China's urban residential energy demand and energy rebound effect. The results show that residents' income level, energy price, temperature deviation, population scale, household size, and district heating system are significant influencing factors of residential energy consumption. Regarding the energy rebound effect, we find that energy price is negatively correlated with the rebound effect, and an inverted U-shaped relationship between residents' income level and rebound-effect size exists. The magnitude of the rebound effect varies across regions, with an average of 65.4%. The main policy implication generated by this study is that it should be in urgent need of energy pricing reform to mitigate the rebound effect in China. [ABSTRACT FROM AUTHOR]
