Application of the Deformed Thiessen Polygon in the Analysis of Layout Influence Factors for Rural Express Delivery Points
In the context of rural revitalization,it is important to explore the layout influence factors of rural express delivery points for rural infrastructure construction.In this paper,we propose the Deformed Thiessen Polygon theory based on the current development status of the Thiessen Polygon theory and the needs for the socio-economic application research.Using the Deformed Thiessen Polygon,this study considers the rural area in Suzhou City,Jiangsu Province(its meaning is explained in the main text)as the study area,with the express delivery points as the specific case.Methods such as Ordinary Least Squares(OLS),Spatial Lag Model(SLM),Spatial Error Model(SEM),and Geographically Weighted Regression(GWR)were used to reveal the layout influence factors of rural express delivery points.The main conclusions drawn from this paper are as follows.(1)The Deformed Thiessen Polygon is an improvement and expansion of the Thiessen Polygon for socio-economic applications.It consists of two parts:the deformation area and the non-deformation area.The deformation area represents a local deformation of the Thiessen Polygon,while the non-deformation area retains the original Thiessen Polygon.The Deformed Thiessen Polygon can effectively solve the mismatch problem between the spatial division of the Thiessen Polygon and actual situations,improving the feasibility and scientificity of social and economic research.(2)Using the service scope as a characterization indicator of express delivery point layout,with this indicator as the dependent variable and population size,economic size,road network density,etc.,as independent variables,we explored the layout influence factors of express delivery points in the study area.When the probability is less than 0.05,the OLS and SLM results show that population size,average slope,and water area are positive influence factors,with population size being the dominant positive influence factor;Economic size is a negative influence factor.The GWR results show that population size and water area have positive spatial effects,while economic size has a negative spatial effect.There are both positive and negative spatial effects on the road network density and average slope.Based on the analysis presented throughout this paper,the main considerations for the development of the rural express delivery industry are as follows.(1)Give full play to the basic guarantee role of public express delivery points.(2)Emphasize the decisive role of population and economic factors.(3)Guide the comprehensive layout for express delivery points.(4)Create relatively equal rural express delivery services.The Deformed Thiessen Polygon helps to advance the development of the Thiessen Polygon,providing a new basis for spatial division in future studies of socio-economic applications.At the same time,the results of this paper have value for understanding the layout influence factors for rural express delivery points and for implementing rural revitalization strategies.
