Abstract

The invention relates to a method and a device for analyzing spatial correlation of an agricultural product price, and aims to solve the problems that the spatial correlation and the spatial heterogeneity of the agricultural product price cannot be accurately reflected in the prior art. The method comprises the following steps: acquiring agricultural product price information; preprocessing the agricultural product price information and matching the agricultural product price information to a map; establishing a highway network data set; calculating an optimal path of every two agricultural product wholesale markets; determining the distance of the optimal path as a traffic distance space weight coefficient between the two agricultural product wholesale markets; calculating global spatial autocorrelation analytical statistic and local spatial autocorrelation analytical statistic of the agricultural product price information according to the traffic distance space weight coefficient between the two agricultural product wholesale markets; generating an agricultural product price spatial correlation statistical graph according to the global spatial autocorrelation analytical statistic, and generating an agricultural product price local autocorrelation distribution diagram according to the local spatial autocorrelation analytical statistic.

Description

Technical field [0001] The invention relates to the technical field of agricultural product price analysis, in particular to a method and device for analyzing the spatial correlation of agricultural product prices. Background technique [0002] The agricultural product market is an important part of the country’s economic, political and social stability. Strengthen the information analysis of agricultural product prices, especially the degree of correlation between the prices of agricultural product wholesale markets, and discover hidden temporal and spatial distribution rules. It is of great significance for agricultural producers and operators to provide scientific and accurate decision-making information. [0003] There are many existing methods for analyzing agricultural product price information. One method uses classic interpolation to draw agricultural product price contours, enclose the contours into contour surfaces, and fill in the corresponding contours according to the ...
