The equipment manufacturing industry is the industrial base of China, which makes it imperative to coordinate the relationship between industrial development and environmental protection. Using panel data of the seven sub-industries in China’s equipment manufacturing industry from 2011 to 2015, this paper evaluates the static and dynamic aspects of green economic development efficiency by combining the super-efficiency slack-based measure model of unexpected output and the data envelopment analysis-Malmquist index model. The results show investments in research and development, and environmental regulations have yielded some positive results, but that regulations have also yielded some undesired output in terms of diminished economic benefits. Pure technical efficiency and scale efficiency have both declined, indicating that the scale and industrial structure need to be further optimized. The results of this study present an objective and comprehensive assessment of green economic development of China’s equipment manufacturing industry and provide valuable insights for improving green economic development efficiency.
