New Energy Demonstration City Pilot Policy, Green Total‑Factor Energy Efficiency, Policy Effects, Difference‑in‑Differences ModelAbstract
With the continuous growth of total energy consumption, non‑fossil energy utilization and energy efficiency have become increasingly important for promoting high‑quality urban development. Policy instruments play a crucial role in improving regional energy efficiency. Based on panel data of 282 prefecture‑level cities in China from 2006 to 2023, this study first measures urban green total‑factor energy efficiency (GTFEE) using the super‑efficiency SBM model. Then, a difference‑in‑differences (DID) model is employed to examine the impact of the New Energy Demonstration City pilot policy on GTFEE. The empirical results show that: (1) The pilot policy significantly enhances urban green total‑factor energy efficiency. (2) By employing the super-efficiency SBM model to measure the green total-factor energy efficiency (GTFEE) of cities, this study evaluates the effectiveness of the new energy demonstration city policy. Furthermore, the mechanisms of its impact are verified through parallel trend tests and placebo tests, providing more targeted evidence for the precision adjustment and optimization of related policies. (3) The effects of the New Energy Demonstration City pilot policy on energy efficiency exhibit notable heterogeneity across cities.
