This paper builds an evaluation index system of the accessibility of network structure based on graph theory and space structure theory. Under the evaluation system, Software of Arcgis10.0 geographic information system and Ucinet 6 are used to analyze the evolution of the accessibility of highway network in Guangdong province (1989-2030)from the perspectives of efficiency, development of regional economy and integration of logistics. The main conclusions of the paper are: 1) the highway system has evolved from linear structure to network, and the accessibility has been promoted apparently. 2) The gap between different areas in Guangdong, including the East Wing, the West Wing, mountainous region and the Pearl River Delta (PRD) is narrowing eventually, but still exists. 3) The logistics centers are set up and spread out from PRD to other regions. 4) Up to 2030, the highway transportation structure are featured by two horizontal and five vertical” main arteries which undertakes huge traffic volume. 5) The development pattern of logistics economy of Guangdong province undergoes a concentration-diffusion
