ABSTRACT: Based on micro-data on water supply listed companies, the three-stage
super-efficiency DEA model is used to measure the efficiency of China’s water
supply enterprises from 2016 to 2020, and tries to combine the evolutionary game method and the Gini coefficient for
further analysis. The empirical results demonstrate that: 1) from the result of
the first and three-stage DEA model, the efficiency values of sample
enterprises show that there is still room for further improvement and development
of enterprise efficiency; 2) according to the subsample analysis, the
efficiency value of large-scale and high-financing
enterprises is higher than that of small-scale and low-financing
enterprises; 3) from the evolutionary game results, when large-scale
enterprises players all chooses a high-financing strategy, and small-scale
enterprises players choose low-financing strategy, the overall balance point of
the game is reached.
