This study employs the Data Envelopment Analysis (DEA) method to comprehensively evaluate the input-output efficiency of 11 businesses on the new energy platform. By constructing an evaluation system that includes capital and labor inputs as well as output indicators such as social benefits, environmental protection benefits, and platform support, the CCR and BCC models are applied to reveal the efficiency levels and potential areas for improvement of different businesses. The research finds that while some businesses have achieved high efficiency, the overall efficiency requires enhancement. It is recommended that the platform optimizes resource allocation, strengthens technological innovation and talent cultivation, expands market cooperation, and improves digitalization to promote sustainable business development and support the implementation of the national energy strategy.
