考虑非期望产出的智能制造企业绿色技术创新效率研究OACHSSCD

Considering the"unexpected output"of intelligent manufacturing in the production process,this paper collects the input and output data of 87 listed intelligent manufacturing enterprises in our country from 2016 to 2023,constructs an evaluation model of green technology innovation efficiency of intelligent manufacturing enterprises,uses the super-efficiency SBM model to evaluate the green tech-nology innovation efficiency of sample enterprises from a static perspective,and comprehensively analy-zes the changing trend of green technology innovation efficiency of enterprises from the dynamic level with the help of GML index.The results show that from 2016 to 2023,the green technology innovation efficiency of listed intelligent manufacturing enterprises in our country is not high,mainly fluctuating and rising,and the progress of green technology innovation efficiency is mainly due to the growth of the technical efficiency change index,while the decline of pure technical efficiency is the main factor re-stricting the improvement of green technology innovation efficiency of enterprises.Finally,based on the research results,relevant management strategies are proposed to enhance the efficiency of green tech-nology innovation of intelligent manufacturing enterprises and comprehensively promote the transforma-tion of intelligent manufacturing enterprises to green production from macro and micro perspectives.
