Abstract
Based on the resource allocation effect, technological innovation effect and competition effect, this paper takes eight comprehensive areas as decision-making units, uses DEA-ENDDF method under the theoretical framework of total factor production with non-radial distance function, calculates energy and environmental efficiency through NDDF of MaxDEA software, makes hypothesis test, and uses Tobit model to analyze the influencing factors of energy and environmental efficiency, such as transportation foundation, economic structure, technological progress, external dependence, energy endowment, population density and other factors are analyzed by regression analysis. Finally, the conclusion is given, in order to explore useful conclusions and explore new ways of energy conservation and emission reduction.

Summary
Along with the economic development and the continuous increase of GDP, China's economy has made brilliant achievements. The current experience of world economic development shows that the sustainable development of economy and the optimization of ecological environment have become an important symbol to measure the high-quality development of a region. General Secretary Xi’s green development concept of "green water and green mountains are golden mountains and silver mountains" profoundly reveals the extreme importance of ecological environment [1]. The total factor environmental efficiency (EEEIn) of three input factors (labor, capital and energy), one expected output (real GDP) and two unexpected outputs (industrial waste gas emission and industrial waste water emission) is calculated by ENDDF method: EEEIn=. EEIn reflects the energy and environmental efficiency, and the value is between 0 and 1. When the value is 1, it means that the decision-making unit is in the frontier of production, and the relative efficiency reaches the optimal level
