Collaborative Research On Urban Distribution And City Development Based On System Dynamics

Modern logistics industry is closely related to living and urban development.As the "Internet +" awakened consumers' demand for efficient and convenient end-of-line logistics delivery service,the national logistics policies have also promoted the breakthrough development of the terminal distribution represented by the urban distribution.The urban distribution and the city's economic,social and environmental development are mutually restricted.It is of practical significance to explore the mechanism and influencing factors between the urban distribution system and the city development system,and to coordinate the urban distribution and the city development.First of all,the paper analyzes the causal feedback relationship between the current situation of urban distribution and city development.It is found that the investment level of urban distribution will affect the construction of urban road network and the construction of information platform.Then,the paper using the Vensim PLE to construct the system dynamics model of urban distribution and city development,and then determines the dynamics equation and parameter simulation determined by the concrete cases of Shanghai from 2006~2015.According to the simulation results based on changed the parameters of distribution investment,it can be concluded that increasing the investment can stimulate the improvement of economy,social development,and significantly improve the state of the ecological environment.The adoption of increasing distribution investment,balancing supply and demand of urban distribution can also effectively coordinate with the urban distribution,city economic and social development.
