Abstract Logistics is the basic industry of the national economy, the efficient circulation of the material to ensure the operation of the social economy. Yunnan Province located in the southwest occupies the "bridgehead" for foreign exchange, whose extent of economic development has great influence on capacity of absorbing foreign economies and the depth of external communication. Enhancing the logistics power is significance in Yunnan province while material exchange becomes as the main form of the world economic communication. To describe the spatial pattern of logistics economy, this paper establishes the L-3D system to analysis logistics economic spatial pattern based on 3D theory of economic geography, which covers the frame of Density, Distance and Division. Yunnan province logistics economic space pattern is obtained with indexes of coefficient of geographic concentration, logistics economic linkages and location quotient to analysis the density, distance and division respectively. The results show that the spatial differentiation characteristics are significant in density of logistics economic. A model of vertical and horizontal diffusion with a center of Kunming is revealed. The outer logistics economy is obviously weak. It shows the development mode of center-channel in division of logistics economic, and development advantages of urban agglomeration in central Yunnan is significant. For division, it is weak in spatial distance of logistics economic in the area of western boundary. Kunming is poor for location quotient, and the development of urban agglomeration in Central Yunnan is discrepant. Dali and surrounding areas is serious in this respect. The similarity was found in the distribution of the logistics and economy in space when drawing the characteristics of spatial pattern of Yunnan Province logistics economy.
