Optimization Of Chinese Regional Port Group Expansion Investment

The port is a key strategic resource of a national and regional development, and operation of the national economy and development of infrastructure and public platform. Since the reform and opening up the Chinese economy and society has undergone profound changes. Since then, not only has made remarkable achievements in the construction of port infrastructure and port capacity to enhance, but also with economic growth and port development approach gradually changing the port increasingly has shown the characteristics of regional development. Because of the Geographical proximity between the port of port in the region and the hinterland of the relative overlap, the port competition is more intense within the port group. So many ports have launched large-scale port expansion investments to improve their own competitiveness. Due to lack of advance planning and overall optimization of the investment, this expansion often gives birth to the excess production capacity resulting in a lot of waste of resources, which does not fundamentally enhance the competitiveness of the port group as a whole. In addition, due to the expansion of investment in port group is a complex systematic project. The great project size, large amount of investment, the long investment cycle, many project links during the expansion result in many uncertain factors, which are difficult to control and can bring many risks. And involving a single port, the port group, economic hinterland and other multi-stakeholder, the expansion of investment problems, are likely to lead to project out of control. So it is very necessary to design a investment optimization model of the expansion of the regional port group and to optimize the port group expansion based on the model.This paper is divided into five chapters:The first chapter introduces the research background and significance, analysis domestic and international port expansion investment research and summary research inadequate; the second chapter on the basis of analysis of regional port group theory, introduces the basic concepts and characteristics of port group influencing factors, and analyzes the effectiveness of the port group expansion investment; the third chapter analyzes the status quo of China’s port throughput and expansion of investment; the fourth chapter establish a optimization model of port group expansion investment; the fifth chapter port takes cluster expansion investment in Shandong Province as an example to validate the model; the sixth chapter summary the whole paper and proposes deficiencies and outlook.Through this study, establish a port group expansion investment optimization model, and it is used in a practical example, and provides a useful reference.
