Study on The Evaluation of Eco-Economic Efficiency in The Yangtze River Economic Zone

Eco-economic efficiency is of tremendous significance to the coordinated development of ecological environment and economy. This study uses the super-SBM model to assess the Yangtze River Economic Belt’s ecological and economic performance from 2011 to 2020. The Malmquist index approach is then used to dynamically analyze the total factor productivity. The findings indicate that there is a non-equilibrium feature in space and that the eco-economic efficiency of the Yangtze River Economic Zone as a whole exhibits a fluctuating rising trend. A downstream > midstream > upstream pattern is shown. Based on the dynamic Malmquist index and its decomposition, the Yangtze River Economic Zone’s total factor productivity has a robust upward tendency. The primary cause of the shift in total factor productivity is technological advancement.
