Estimation Of Ecological Environment Satisfaction In Yunnan Province And Analysis Of Influencing Factors

With the development of science and technology and industrial progress,people are increasingly damaging the environment.Environmental problems have evolved into global issues that affect the development of the human community.Relevant data show that Yunnan Province is in a period of serious environmental pollution and ecological destruction.Since 2003,the discharge of major pollutants in the whole province has rebounded in a large area,and the scope of ecological environment damage has been expanding.Therefore,sustainable development is facing huge challenges.In January 2015,Xi Jinping,general secretary of the investigation of Yunnan,further emphasize the ecological environment protection in a more prominent position,in Yunnan pointed out the "national unity progress demonstration area,ecological civilization construction vanguard,facing southeast Asia radiation center in South Asia" three new strategic positioning,the meaning of ecological civilization construction in Yunnan Province is more outstanding and important.In recent years,despite government efforts to continuously strengthen environmental protection,some official data also show good results,the environmental protection the issue for the government,enterprises and academic research,the current academic circles for the relationship between environmental pollution and economic growth,environmental pollution and the relationship between the industrial structure,the comprehensive evaluation of ecological environment pollution problem has been extensive research,but from all walks of life to the ecological environment satisfaction research is still in its infancy stage,is very rare in the searchable literature.It is of great historical significance to study the public's attitude towards,or satisfaction with,the ecological environment of Yunnan Province,and to explore the factors influencing the satisfaction with,the ecological environment of Yunnan Province.It is of great practical significance to further reflect the problems and shortcomings in the construction of ecological environment in Yunnan Province,and to improve the work and promote the construction of ecological civilization on this basis.This paper carries out exploratory analysis on the data of the 2018 public ecological environment satisfaction survey in yunnan province,which consists of five parts.The first part sorts out the domestic and foreign research literature on ecological environment,satisfaction and ecological environment satisfaction.It is found that most of the research on satisfaction is to explore the influencing factors,while the measurement of satisfaction adopts the general weighted average method and fails to calculate the estimation error.In addition,there are few empirical studies on the influencing factors of the public's ecological environment satisfaction,which fail to provide feedback mechanism for the public's environmental satisfaction,and are not enough to constitute a theoretical system to provide further environmental policy reference for the government.On this basis,the research ideas and methods of this paper are proposed,and related concepts and theories are explained in detail according to the research methods adopted in this paper,laying a foundation for the empirical analysis in the following.The second part introduces the data sources of this study and preprocesses the original data to delete the missing data in the questionnaire.Next using the common methods and knife method to estimate the overall ecological environment of Yunnan Province satisfaction,results show that both on the satisfaction score and ranking has a certain difference,compared with common methods,knife method takes into account the hierarchical structure of the sample to estimate,and gives the estimation error,relatively more accurate estimation results.The third part analyzes the influencing factors of ecological environment satisfaction in Yunnan Province.First,the distribution of overall ecological environment satisfaction is described,and the differences caused by different sample backgrounds are analyzed.Then,using the binary logictic regression model,the regression analysis was conducted on the overall ecological environment satisfaction and various indicators,and the indicators with significant influence on the overall ecological environment satisfaction in different cities and towns were found.Finally,due to the regression model is a single index is adopted to directly affect the overall ecological environment satisfaction,the index may exist between the indirect effect,this paper further USES the structural equation model analysis,observe the indexes have indirect effects on whether the overall ecological environment satisfaction,to explore the influence mechanism of more complex.The fourth part summarizes the conclusions of this study,and puts forward corresponding Suggestions,including the general Suggestions at the overall level of Yunnan Province,and the different Suggestions for different states.The innovations of this paper are as follows: first,the non-parametric estimation method of knife-cutting is applied to the calculation of satisfaction score,which is more accurate than the traditional simple weighted average method.The estimation error is also given to verify the assumed error in sampling,which is impossible to calculate the satisfaction score in the past.Second,in-depth exploration of the influencing factors of ecological environment satisfaction and the feedback of the public on different indicators of ecological environment satisfaction are conducive to the further improvement of government environmental protection policies.
