Environmental pollution is an anthropogenic phenomenon as a consequence of the industrialization process. Therefore, the balance among energy-economy-pollution performance becomes increasingly important. However, industry heterogeneity exists in the economic system, which makes industry performance differences. This paper focuses on the industrial performance evaluation in China based on the green input-output accounting. For the industrial heterogeneity, a four-stage dynamic Malmquist model is ...
