In the forming of the Dynamic System of Tourism Development (DSTD) in developed regions from theview of supply side, the Delphi Method and the Analytical Hierarchy Process(AHP) are used to count the weight of eachcomponent of the DSTD. It has been found that the attraction subsystem is the most important one of the three subsystemsat the firt hierarchical level of DSTD, which means that tourist attractions are always the principal factors for regionaltourism development, even in developed regions. But it is also noteworthy that the significance of the attraction subsystemis not dominant in the DSTD. At the second hierarchical level, the physical attraction subsystem rank No. 1, while theweight of the non-physical attraction subsystem is just a little larger than the weight of the hardware subsystem and that ofsoftware subsystem. And the weights of the three components in the medium subsystem are similar. The top 3 factors atthe third hierarchical level are scenic spot, location and regional economic impact. The result verifies the conclusions ofqualitative analysis, which depends on the market research and the study of historical date, that the most important component of the DSTD in Feshan is the impact of the developed economy. Knowing the weight of each component of the DSTDcan be helpful to make out the most useful force, furthermore to determine the future orientation for regional tourism development.
