A Method For Identifying The Industries That Have Location Preference For Proximity To Ports And Optimizing Their Spatial Distribution In The Port-Metropolise

The era in which the ports become larger and larger has arrived. On one hand, both the number and size of port infrastructure has been increasing continually. One notable example is that the port terminals have become larger, more complex, more information-based, and more automatic. On the other hand, the port operators tend to develop new business and provide new service, which promotes the upgrading of ports towards "the fourth generation" or even higher generation (i.e. the so-called "the 3+Xth generation"). As a result, the types of business and operations which ports are engaged in have become more varied, more industry-chain-focused and more transboundary.Both the larger size of infrastructure and the diversification of service types have led to the agglomeration of more industries and population in the port neighboring areas. Besides, to fully utilize their superiority in location and boost their economy, port-cities are providing active support for developing the industry clusters in the port neighboring areas, which further enhances the location advantage of port neighboring areas and thus attracts more industries and population. As a result, driven by the larger size of terminals, the agglomeration of industries and population in the port neighboring areas, as well as their multiplier effect, a new kind of "Port-Metropolises" which covers a huge area, has come into being.Therefore, it is necessary to study the category of industries which are suitable to be developed in the new port-metropolis from the perspective of the industry chain and the global transport network, and to optimize the spatial distribution of industries and population in the new port-metropolis using the land-use modeling techniques, which would have great significance for improving the efficiency of port-metropolis, realizing its sustainable development, and reaching the expected goal of boosting economy.Under such background, this dissertation aims to study:1) screening the categories of industries to select those industries which are suitable to be located in the port neighboring areas. To solve this problem, the optimized locations and corresponding distribution of the manufacturing industries are investigated in the integrated transport network (both the maritime network and inland network are included, and the two networks are connected by ports) by proposing the industry location models. Based on the optimized locations of certain industry, the appropriateness for the industry to be located in the port neighboring areas could be judged. Therefore, both the categories and size of the industries which are suitable to be developed in the port-metropolis could be determined by using this method.2) optimizing the land-use pattern of the port-metropolis. To solve this problem, a new land-use optimization method is proposed,. By using this method, the optimal distribution of the industries and population in the port-metropolis could be determined considering the maximum of economic benefit and social benefit. The dissertation is conducted as follows:Firstly, based on the location principals for the facilities which provide service for the flow-based demand, the Flow-Capturing Location Model for the manufacturing industries is proposed. In the model, the raw materials are converted to the same substance as the products, and the flows of the substance are calculated based on their route choice behavior, and then the optimal locations of the industries in the integrated transport network are determined through the flow-capturing calculation.Secondly, due to the shortage of the Flow-Capturing Location Model, the Location-Allocation Model for the manufacturing industries is proposed based on the location principals for the facilities which provide service for the node-based demand, which further improves the method for screening the port-related industries. In the model, the integrated transport network is split into the sub-networks of raw materials and products, and the distribution/allocation of raw materials and products are calculated in each sub-network, and then the optimal locations of the industries in the integrated transport network are determined considering the minimum of total cost.Thirdly, to optimize the distribution of different land-uses in the port-metropolis, the land-use optimization model is proposed, considering the interaction in spatial distribution between the industries and population, and taking the maximum of GDP and the maximum of residential utilities of households as two objectives,.Fourthly, the heuristic solution is designed to solve the proposed land-use model.Finally, to test its feasibility, the proposed land-use optimization method is applied, taking Dalian Taiping Bay Economic Area as an example.
