Abstract
This study evaluates the impact of green finance policies on investment efficiency in new energy industries using a DEA-Malmquist index approach. By analyzing panel data from 30 Chinese provinces (2015–2022), the research quantifies dynamic changes in investment efficiency and decomposes them into technological progress, technical efficiency, and scale efficiency. The results indicate that green finance policies significantly enhance investment efficiency, with regional heterogeneity observed due to variations in policy implementation and resource endowments. The Malmquist index reveals that technological innovation driven by green financing is the primary contributor to efficiency gains. Policy recommendations are proposed to optimize green financial instruments and address inefficiencies in capital allocation.
