THE STATISTICAL STUDY ON GREEN ECONOMY EFFICIENCY IN ECO-ECONOMIC BELT

The construction of the Hanjiang Eco-economic Belt has been included in China's development plan. The region has significant location advantages and huge development potential. Adhering to the concept of green development, realizing the coordinated development and organic unity of economic and social development and ecological environmental protection is important for promoting the economic and social development of the region. Sustained development plays an important role. Based on the existing research results, this paper focuses on the three industrial wastes, and considers environmental pollution as an undesired output into the calculation of economic efficiency. Construct a comprehensive index reflecting the impact of environmental pollution on the economic efficiency of the Hanjiang River Eco-economic Zone. Based on the analysis characteristics of the DEA model. measure the traditional economic efficiency and green economic efficiency of the Hanjiang Eco-economic Zone, and analyze its trend change level. The research results show that the green economic efficiency of most cities in the Hanjiang River Ecological Economic Zone shows an upward trend, and the fluctuation range is smaller than that of the traditional economic efficiency. The unevenness of the green economy efficiency of the cities in the Hanjiang Eco-economic Belt is more prominent, and the green economy efficiency of upstream cities is higher than that of downstream and midstream cities. There is a U-shaped relationship between the green economic efficiency of the Hanjiang Eco-economic Zone and the level of economic development.
