The Evolution of the Tourism Industrial Chain of the Margin Area of Metropolitan Cities: A Case Study of Lintong District, Xi'an
以西安临潼区为例，用有向图和生灭过程分析旅游产业链的动态演化，并用马尔可夫条件转移模型模拟其发展，发现产业链扩张能促进区域经济增长和城市形态改善。
The development of the tourism industry chain has played an increasingly prominent role during the development of Chinese tourism industry since 2000.Based on the directed graph and the birth and death process,this paper analyzes the dynamic evolution of the tourism industrial chain by taking Lintong District of Xi'an as a case area.The dynamic evolution process of the tourism industrial chain is also simulated by constructing the dynamic random statistical model of Markov condition transfer process aided by the economic leakage restriction conditions.The results show: tourism industrial chain expansion in Lintong District will become an important growth point in promoting the regional economic development and improving the urban social shapes;its tourism industry chain will also be improved and perfected gradually at the same time.
