Based on different flows such as population, goods, capital and information, complicated economic linkage net- work has been formed. Gravity model and social network analysis are major methods to measure the intensi- ty of urban or regional economic linkage and spatial relationship pattern. Firstly, the paper collects traffic and socio-economic statistic data of research area in 2002 and 2012. We establish attribute and spatial datas- et by ArcGIS software. Secondly, the article uses gravity model and measures intensity of urban economic linkage of Guanzhong-Tianshui Economic Zone for 2002 and 2012. Thirdly, using social network analysis method, this paper chooses some different indexes like degree, network density, centralization, clustering
