长株潭城市群新型农业经营主体时空格局演变及其影响因素分析
Analysis of the Spatiotemporal Pattern Evolution and Influencing Factors of New Type of Agricultural Operating Entities in the Chang-Zhu-Tan Urban Agglomeration
摘要
Abstract
This study takes the new entities in the Chang-Zhu-Tan Urban Agglomeration as the research subject.Methods such as kernel density,along with geographical detector and Geographically and Temporally Weighted Regression(GTWR),are employed to analyze the evolution of the spatiotemporal pattern of new entities in the urban agglomeration at the time nodes of 2017,2020,and 2023 as well as its influencing factors and propose spatial optimization strategies.Results show the following:(1)The total number of new entities in the urban agglomeration shows an upward trend,with a growth rate that first increases and then decreases,exhibiting a phased characteristic;the type structure has shifted from being dominated by leading enterprises to being dominated by family farms,and the industrial type structure has shifted from being dominated by processing to being dominated by planting and processing.(2)New entities in the urban agglomeration are significantly clustered,and the degree of clustering has shown an increasing trend over time,with the clustering degree in the northern part of the urban agglomeration being significantly higher than that in the southern part.The clustering pattern has evolved from"two main and multiple secondary"to"three main and three secondary"and then"two main and three secondary."Both the main and secondary cores are distributed in the core and edge areas of the northern metropolitan circle,and there is a certain correlation between the clustering space and the circle-layer structure of the urban agglomeration.(3)The spatial patterns of the five major categories of new operators,based on industrial type,are different;however,they all show significant clustering with similar main cores.(4)Agricultural characteristics and innovation and the level of agricultural modernization are the core factors that influence the spatial distribution of new entities in the urban agglomeration.The main factors influencing the spatial patterns of new processing-type entities and other types of new entities show certain differences.(5)Based on holistic thinking and differentiated strategies,countermeasures and suggestions for promoting the development of new type of agricultural operating entities are proposed for the overall urban agglomeration as well as for each circle layer of the core area of new entities in the urban agglomeration,the core edge area of new operators,and the southern remote suburban counties.关键词
