Evolution Of Environmental Technical Efficiency Of Grain Production And Analysis Of Influencing Factors In Poyang Lake Eco-economic Zone

Grain is an important strategic material,which is related to the people's livelihood,social harmony and stability and national security.Grain security is one of three major economic security in the world.At present,China is in an important period,which it's accelerating industrialization and urbanization.It's fundamental for the stable and sustainable development of the country's economy to ensuring grain security.Under the premise of limited land resources,it's the way for increasing grain production to expanding grain planting area,which is more and more restricted.At present,the use of fertilizer and pesticides in our country makes the soil harden,eutrophication and deterioration of water quality,the problem of sustainable grain production is becoming more and more prominent.It's an inevitable trend to increasing grain production and protecting the environment by increasing production efficiency.Poyang Lake Ecological Economic Zone has always been a traditional agricultural area and main grain producing area in Jiangxi Province.It explores the differences and the processes of the evolution of environmental technological efficiency of grain production and discusses the relationships between grain production and environment.The paper analyzes the factors that affect the technical efficiency of grain production environment,and it is helpful to grasp the utilization situation of agricultural science and technology correctly,which is related factors in Poyang Lake Ecological Economic Zone,and coordinate the development of grain production environment,it's significance to realize the sustainable development of grain economy.Therefore,this paper uses the direction distance function to calculate the traditional technical efficiency and environmental technical efficiency in Poyang Lake Ecological Economic Zone,analyzing and ranking the difference between the spatial and temporal disparities to reveal the spatial meanings of different counties.This paper explores the coordination between grain production and environment in Poyang Lake Ecological Economic Zone by using Arcgis10.1 space measurement software.Based on this,the fixed effect model is used to analyze the ecological environment of Poyang Lake Ecological Economic Zone's factors of grain production environment technical efficiency analysis.To reducing environmental pollution and increasing the production and security of grain,the paper provides a more reasonable,more scientific and more effective policy recommendations.The main framework of this paper is as follows:Chapter 1,Introductions.This chapter mainly introduces the research background and significance,at home and abroad on the grain production efficiency and environmental technical efficiency analysis and evaluation of the literature review,and expounds the research contents,research methods and technology roadmap,summarizes the innovation and shortcomings of this paper.Chapter 2,The related concepts and theories.This chapter discusses the concept of grain,technical efficiency and environmental technology efficiency,and combs the theory of location,comparative advantage theory and sustainable development.Chapter 3,Evolution of environmental technical efficiency of grain production in PLEEZ.This chapter makes a calculation and comparative analysis of the technical efficiency and traditional technical efficiency of grain production environment in Poyang Lake Ecological Economic Zone,and discusses the coordination of grain production and environment in Poyang Lake Ecological Economic Zone.Chapter 4,Analysis on the factors influencing environmental technical efficiency of grain production in PLEEZ.This chapter is based on the actual situation of grain production in Poyang Lake Ecological Economic Zone,and it uses the fixed effect panel data model to analyze the factors that affect the technical efficiency of grain production environment in Poyang Lake Ecological Economic Zone.Chapter 5,Conclusion,recommendations and prospect.This chapter gives a comprehensive summary of the contents of the paper,and puts forward relevant policy suggestions on the basis of this paper,and puts forward the prospect of further research in the future.
