Abstract: This paper proposes a matrix network DEA method based on the global DEA framework. This method avoids treating the decision-making unit as a 'black box', and the overall efficiency of the combined system and the efficiency of each subsystem can be obtained by it, and the convergence of the efficiency value is tested by δ convergence test, β convergence test and club convergence test. Empirical results show that the whole, regional and provincial ecological economic efficiency levels are low. All subsystems of the ecological economic system in the eastern region are in a leading position. The economic and social efficiencies in the central region are higher than the western regions, but its ecological efficiency is lower than the western region. In addition, the results of efficiency convergence test show that the overall and social efficiencies have a divergence trend, while economic and ecological efficiencies keep steady.
