Due to the rapid development of the Shaanxi Gansu Ningxia border region economy, county region in the regional development in the status and role of the increasingly prominent, in Shaanxi, Gansu and Ningxia county economic ties between is more active, in spatial pattern basic formation of network characteristics, and in a new, unique style, structure, speed development. In this paper, the Shaanxi Gansu Ningxia 216 County between highway traffic accessibility in the time distance, reflect the pros and cons of county economy of 15 indicators, using entropy method to determine the weights and calculate the overall quality of the city. With the help of gravitational interaction model, and combined with social network analysis method to the Shaanxi Gansu Ningxia border region 216 county economic ties, the network structure of and analysis of structural characteristics of regional county-level units of the economic ties between the characteristics of county economy and network.From the strength of economic ties among the county: provincial differences,Shaanxi Province internal counties economic ties is most closely accounted for 97.2%of the total economic contact; city under the jurisdiction of counties economy strong ties to other county; economic contact intensity and road network density was positively correlated, regional traffic network density is high, the strength of economic ties. From the point of view of the direction of the contact strength of county economy: space or adjacent County near in distance, the more closely the degree of economic ties; center city is regional economic and social development of the dispatch center, service center, regulation center and center drive, can the strong role of the center of the neighborhood and the surrounding region's economic construction and development; road network facilities is the county foreign economic relations, an important channel.Through the analysis of the Shaan Gan Ning county domain economy network structure can be drawn: Shaan Gan Ning county domain economy network density is acceptable, the network of county city nodes in the regional economic development,mutual cooperation to the contributions, also produced a certain influence.
