Spatial-temporal Characteristics And Influencing Factors Of Agricultural Green Development In Northeast China

China is one of the origins of agriculture in the world,with a history of thousands of years of agricultural civilization development.In traditional culture,both the ideal family model of "farm home" and the production mode of "work at sunrise and rest after sunset" coincide with the harmonious development concept of happy life,inclusive cooperation and advocating nature.However,after entering the new century,our agricultural development enters the bottleneck period.On the one hand,the shortage of land resources,the severe soil erosion and the serious environmental pollution have become the main obstacles to the agricultural development in our country.Agricultural green development is the only way to achieve sustainable agricultural development.On the other hand,with the continuous development of economy and society,people’s living standards and requirements for the quality of agricultural products are also continuously improving.As a result,the demand for green agricultural products is also g rowing.For China’s important grain production base in the northeast region,more attention should be paid to the green development of agriculture,improve agricultural ecological environment,improve farmers’ quality of life,and promote the overall development of agriculture.Therefore,it is necessary to study the characteristics and influencing factors of agricultural green development in Northeast China.In this paper,the agricultural green development in northeast China is selected as the research object,and the relevant concepts and theoretical basis are comprehensively sorted out,and the agricultural green development in Northeast China is comprehensively analyzed.First,on the basis of the existing research and the actual situation of Northeast China,the evaluation index system was constructed from four aspects: life security,resources and environment,green production and quality and efficiency.The entropy weight method was used to determine the weight of specific indicators and agricultural green development index.Second,the dynamic change characteristics of agricultural green development in Northeast China from 2000 to 2020 were analyzed,and the development trend and temporal and spatial characteristics of each index were summarized.Third,based on the above dynamic analysis,eight variables including industrial agglomeration level,economic structure,planting structure,industrial structure,industrialization level,per capita GDP,number of institutions of higher learning,and total sa les volume of wholesale and retail trade goods above quota were selected to construct a static panel model,and correlation analysis and collinearity test were conducted on the eight variables.On this basis,this paper makes an empirical study of Northeast China and puts forward relevant countermeasures and suggestions.The research conclusions of this paper on Northeast China are as follows:(1)The overall green development of agriculture in Northeast China is on the rise.Among them,Dalian City and Panjin City agricultural green development has been at a high level.In the time line,the green development of urban agriculture in Northeast China presents a positive trend of continuous growth of living security,recovery of resources and environment,i mprovement of green production,and substantial growth of quality and efficiency.In terms of spatial dimension,the high zone of agricultural green development in Northeast China is mainly distributed in the eastern part of the Greater Khingan Mountains-Huludao axis,the high zone of living security is mostly distributed in the central and southern part of Liaoning Province and the northeast part of Heilongjiang Province,and the high zone of resources and environment is mostly distributed in the border of northeast China.The green production high zone is distributed in the core area of northeast China,and the quality and efficiency high zone is distributed in the eastern area of Heihe-Hulunbuir axis,and the quality and efficiency level increases gradu ally from west to east.(2)The empirical results of influencing factors on agricultural green development in Northeast China show that industrial agglomeration level,economic structure,industrial structure,per capita GDP,number of institutions of higher learning,total sales volume of wholesale and retail trade goods above quota are positively correlated with agricultural green development at different significance levels,all of which can promote agricultural green development in Northeast China to varying degrees.However,industrialization level and planting structure are negatively correlated to green agricultural development.At the same time,in different regions,the influence of various factors on agricultural green development is heterogeneous.According to the results of quantitative analysis,corresponding countermeasures and suggestions are put forward for further promoting the comprehensive green transformation of agriculture in Northeast China..
