With the rapid economic development,the problems of environmental degradation,ecological imbalances,and resource depletion are becoming more and more life-threatening.For a long time,as an important ecological barrier and strategic channel in Northwest,Gansu Province,has been in an important strategic position in the construction of ecological civilization in China.Therefore,analyzing Gansu's ecological civilization's development level and its influencing factors are of great significance to the coordinated development of Gansu's society,economy,resources,environment,and people's livelihood.Based on the current environmental situation in Gansu Province,this article draws on the experience of designing the relevant indicator system for the construction of ecological civilization at home and abroad science,perfection,and meeting the requirements of the current situation of ecological civilization construction.Eco-environmental protection and ecological quality of life have built an indicator system of ecological civilization construction with 41 indicators.First of all,using the principal component analysis method to give it weight,carry out a comprehensive evaluation of the level of ecological civilization construction in Gansu Province from 2004 to 2017;and use the method of entropy value and coupling coordination model to study and analyze the level of coupling and coordinated development of ecological civilization construction in Gansu Province.Secondly,using data envelopment method to make an empirical analysis of the efficiency of ecological civilization construction in Gansu Province from 2004 to 2017 from both dynamic and static aspects;Finally,on the basis of empirical conclusions,it is proposed to improve Gansu Province from the perspective of promoting ecological civilization Policy recommendations for the level of ecological civilization construction.The main research conclusions are as follows:(1)The current status of the development of ecological civilization in Gansu Province is mainly reflected in low economic level,irrational energy structure,imperfect infrastructure,low resource utilization efficiency,complex ecological environment,imperfect system construction,and weak ecological awareness.(2)It can be seen from the principal component analysis that the development level of ecological civilization construction in Gansu Province has continued to increase from 2004 to 2017,but its development stage is at a relatively low level.The development level of each subsystem is fluctuating,the proportion of the primary industry,tertiary industry,growth rate of total fixed-asset investment,and growth rate of total retail sales of social consumer goods are the main factors restricting social and economic development;nature reserves occupy jurisdiction the proportion of area,forest coverage,green coverage of built-up areas,and per capita urban road area are the main factors that restrict the optimization of land space;per capita energy consumption and the proportion of R&D in GDP are the main factors that restrict the use of resources and energy;the harmless treatment of urban domestic waste the rate,urban sewage treatment rate,10,000 yuan GDP carbon dioxide emissions,10,000 yuan GDP solid waste output,10,000 yuan GDP wastewater discharge is the main factors restricting ecological,environmental protection;public library storage per 100 people,unemployment rate,urban residents Engel coefficient The the proportion of urban and rural residents' income level is the main factor restricting the quality of ecological life.(3)According to the coupling and coordination model,the coupling degree and coordination degree of the comprehensive system of ecological civilization construction in Gansu Province in 2004-2017 are at a continuously rising level and the coupling degree has experienced three development stages of low-level coupling stage,antagonistic stage,and running-in stage respectively;The coupling coordination degree has experienced a stage of moderate dysfunction recession,a mild stage of dysregulation recession,an imminent stage of dysregulation development,a stage of primary disorder decay,and a stage of intermediate disorder decay.(4)Based on DEA's CCR and BCC models,it can be seen that the efficiency level of ecological civilization construction in Gansu Province from 2004 to 2017 did not reach the state of effective production frontier,but the overall growth trend year by year;the level of pure technical efficiency reached the effective production frontier in a short time;however,its state is unstable,and to a certain extent there are problems of waste of resources and ecological pollution;the overall level of scale efficiency is high and shows a year-on-year growth trend;scale returns show a the trend of slowly increasing year-on-year fluctuations;technical efficiency changes,technical changes,changes in pure technical efficiency,changes in scale efficiency and changes in total factor productivity all showed a gradual increase in fluctuations;the seven input indicators all showed varying degrees of redundancy,improved projection values,and potential optimization values.(5)Improving the development level of ecological civilization construction in Gansu Province can be achieved through the following aspects: improving agricultural production and resource proper utilization.Optimize the internal structure of the industry,speed up the process of new urbanization,optimize the land and space development pattern and create a good legal environment.
