Factors Environmental Efficiency Measurement And Impact Airline

Civil aviation plays in the strategic wisdom of social construction and transportation powerhouse in an irreplaceable role,but also a major source of emissions of carbon dioxide,carbon emissions on the environment resulting in a greater negative impact.The face of global climate change alarm,carbon emission reduction situation is increasingly urgent civil aviation industry,airline carbon emissions as the main brunt of the civil aviation industry,airlines environmental efficiency is a measure of core indicators airline of low-carbon transport capacity.Therefore,in this context,scientific and accurate measure of the efficiency of the airline environment,and measure the results to find important constraints affecting the airline of low-carbon transport capacity based on environmental efficiency,and propose targeted airlines environmental efficiency improvement measures,to achieve Civil aviation green development,reduce development and environmental constraints at home and abroad breakthrough in the civil aviation industry.This article will examine the environmental efficiency of the airline placed under the dual perspective of carbon emissions and airline traffic growth of airlines based on actual production data,production build index system output airlines.On this basis,the use of undesired SBM model and GML production index for airline representative 20 2010-2017 environmental efficiency between static analysis and dynamic analysis,and further use of Tobit regression model of the impact of environmental efficiency Airlines factors affecting the empirical analysis.Static analysis showed that environmental efficiency: the gap between the static environment samples airlines greater efficiency,there is much room for improvement most environmentally efficient airlines.Secondly,the overall efficiency of a static environment does not mean the study period showed an increasing trend,indicating a strong factor in stimulating the growth of environmental efficiency inside and outside the airline lacking.Dynamic environmental efficiency analysis showed: a dynamic environment overall efficiency of our civil aviation industry in 2010-most improved slightly between 2017,technological progress,the result of the combined effects of pure technical efficiency and scale efficiency.Impact of environmental efficiency affect the efficiency of the airline’s empirical analysis found: the average flight distance,load factor,market share,cargo and mail turnover ratio can promote improved environmental efficiency for airlines.Improve ton-km fuel consumption has a negative influence on improving the environmental efficiency of the airline.Finally,based on empirical analysis results,the airline specific measures to improve environmental efficiency from the airline itself level with the competent department level two levels.
