    Since the reform and opening up, China's economy has achieved rapid development, but problems such as low energy efficiency and environmental pollution have become prominent. In September 2020, the Chinese government will take "carbon neutrality" as China's long-term goal, and the improvement of energy efficiency is an important way to achieve "carbon neutrality". In recent years, China's commodity marketization process has become increasingly perfect, but there are still many problems in the marketization of production factors, resulting in the resource misallocation between capital and labor, which has an adverse impact on economic efficiency. Therefore, this paper aims to study the impact of resource misallocation on energy efficiency in various provinces of China, so as to provide a theoretical basis for the improvement of energy efficiency and the realization of "carbon neutrality" in China.

    This paper measures the energy efficiency and the resource misallocation in various provinces of China. Firstly, taking carbon emissions as unexpected output, the super efficiency SBM-DEA model is used to measure China's energy efficiency. The measurement results indicate that China's energy efficiency shows a downward trend in recent years.Then the "price-tax" model is used to calculate the degree of resource misallocation. The measurement results show that the resource misallocation in China has been improved on the whole. Finally, based on the measurement of the two, a panel regression model is constructed to analyze the impact of the resource misallocation on energy efficiency. On this basis, the impact mechanism is studied by using the mediation model, and the nonlinearity of the impact is analyzed by using the threshold regression model.The results of benchmark regression show that capital misallocation, labor factor misallocation and overall misallocation will have an adverse impact on energy efficiency, and this impact is heterogeneous due to different regions and misallocation types.

    In order to further investigate the path of the impact of resource misallocation on energy efficiency, this paper uses the mediation model to analyze it from the perspectives of innovation ability and industrial structure upgrading. The results imply that in addition to the direct effect, resource misallocation will also affect regional energy efficiency by affecting regional innovation ability and industrial structure level. Due to the regional heterogeneity of the impact, the threshold regression model is used to analyze the possible nonlinear relationship between the resource misallocation and energy efficiency by taking the level of economic development and the degree of factor distortion as the threshold value. The regression results show that when the regional GDP and factor distortion coefficient are in different intervals, There are differences in the impact of resource misallocation on energy efficiency. Based on the empirical analysis, this paper puts forward the countermeasures to improve China's energy efficiency from the aspects of adjusting measures to local conditions, factor marketization reform, factor market unification, optimizing industrial structure and improving innovation ability.
