The post-crisis era, in response to the financial tsunami, the central government for the expansion of domestic demand to maintain steady economic growth in China, the timely adjustment of macroeconomic policy, the implementation of fiscal policy and moderately loose monetary policy to increase investment in transportation infrastructure. The central government announced a 4 trillion investment plans, local governments have announced investment plans of nearly 18 trillion. Therefore, our transportation is bound to usher in a new period of development. Therefore, it is necessary to use the idea of ??early warning management, transportation economic system of early warning research, dynamic monitoring of regional transportation economic system run trend, timely warning of potential danger signals, in order to take effective measures to promote economic and scientific development of transportation and harmonious development. Transportation and regional economic interaction between this article from the point of view of the system analysis, system dynamics framework, application of the transport system analysis, measurement of econometric models and computer means, qualitative analysis and quantitative research combined analysis of transportation economic system The interactive mechanism of regional economic system established transportation economy system dynamics early warning system model, and an empirical study in Fujian Province, \This paper studies the content is as follows: First, the paper home and abroad warning, transportation, regional economic and system dynamics theory research-based clear connotation of transportation economic early warning system, features, transportation economic system dynamics The ideas and methods of the early warning system, as well as early warning modeling ideas. Second, the analysis of the interaction between transportation and regional economic relations, the use of system dynamics theory, to determine the boundaries of the research system, system elements, analysis of the causal relationship between the elements of the system, according to the causal feedback traffic The transport economic early warning system dynamics model. The portion of the core papers. Finally, Fujian Province, for example to verify the feasibility of early warning models of transportation economic system dynamics. Quantitative analysis based on existing statistics and historical data, by running the model, Fujian transportation economic system variable changes, based on a the Vensim software simulation analysis, based on simulation results under different development strategies of Fujian Province, the transportation economy system \
