Coordinated Development Of Jiangdu Port City Under The Background Of New Economic Normality

With the further development of economic globalization,the trade between countries around the world has become increasingly frequent,which has led to the development and prosperity of port economy.Ports rely on special geographical location to become the hub of distribution of goods.The distribution of goods brings port transportation,logistics,commerce and industrial agglomeration.The city's economic system and port industry are increasingly closely linked,and the rapid development of the port has led to the prosperity of the port city's economy.The prosperity of the city's economy is feeding back the development of the port,improving the port infrastructure,improving the port throughput and further enhancing the port's function through the investment in the construction of the port.Therefore,the relationship between port and city should be coordinated,interactive and mutually reinforcing.However,in the context of the new normal economy,some ports,especially the bulk of the main business such as iron ore and coal,will face difficulties,which will lead to the weakening of the port's economic driving effect on the hinterland.Long.Under such background conditions,we should study the interactive relationship between the port and the city,and develop the factors and problems that obstruct the interactive development of the port and city under the current background,and make adjustments in time.Through the detailed analysis of the internal relations of Jiangdu port and city system,the relationship between the internal elements of the system is clarified,the causality loop diagram of the port city system is drawn,and the dynamic flow chart of the Jiangdu port city system is established on the basis of the causal loop analysis.By means of data acquisition and expert consultation,the parameters of system equation and system elements are reasonably set up,and the validity of the simulation is checked.According to the basic situation of Jiangdu district and port,a reasonable policy simulation scheme is set up.Through the comparison of the simulation results of the scheme and the basic simulation,the Countermeasures of the coordinated and interactive development of the Jiangdu port and the city are obtained.Through the study of Jiangdu port city system,it is found that the Jiangdu port production system is a benign interactive system,and all economic indicators perform well.In the future economic development of Jiangdu,the contribution of the third industry is bigger and bigger,and become the pillar industry of economic development.On the driving force of economic development,innovation driven will replace the traditional factor input to drive the main driving force of Jiangdu's economic take-off.
