Agricultural Supply And Demand Matching System Research Base On Network Analysis

Agriculture is the foundation of national economic development ofChina as a large developing country. For a long time,“issues concerning agriculture,countryside and farmers” have always been the important problems in the economicdevelopment of our country. Agricultural product, as an indispensable component ofissues, is characterized by obvious time and regional differences. At present, theexisting agricultural information systems solve the sharing problem of prices andsupply and demand information of agricultural products, but trading matchinginformation of supply and demand is rarely provided and eventually path planning ofpurchasing and sale based on matching information can’t be provided.With the rapid development of Internet technology and the advancement ofinformation technology, more and more trades are carried out through Internet, somatching system has become a research focus of online trading. Through matchingsystem, the supply and demand information which the users focus on is matchedaccording to certain rules so that the best information which meets the customers’demand is selected and eventually users can cooperate with the trading partners.In this paper, according to time and regional differences existing in supply andmarketing of agricultural products and combining with spatial analysis ability of GIS,agricultural product supply and demand matching platform is established. And then,matching rules of agricultural products supply and demand information based onnetwork analysis is discussed and combining with online map, paths for dataacquisition and update mechanism are built to provide corresponding path planning ofpurchasing and sale for the suppler and demander.This paper, based on the interest of supplier and demander, price as well as supply and demand data of agricultural products, designs and develops agricultural productsupply and demand matching platform based on network analysis with the functionssuch as information matching of agricultural product supply and demand, extractionand update of online road network data and schedule planning of purchasing and sale,which makes up for the deficient matching of agricultural products supply and demandinformation, provides auxiliary means for supplier and demander to make decisionsinvolving agricultural product trading, so as to safeguard the interests of both partiesand improve the level of solving “issues concerning agriculture, countryside andfarmers”.
