本科论文摘 要随着京津冀城市群社会经济发展水平的不断攀升，核心城市对周边区域的带动作用不断扩大，京津冀地区协同发展取得了巨大的成效。目前三地为了继续扩大协同发展的战略成果，签署了一系列新一轮的合作框架协议，巩固更加多层次的协作关系。但是由于京津冀地区边缘城市与核心城市的经济发展差异较大，同时受行政体制的约束与影响，京津冀一体化发展的进程缓慢。同时，京津冀港口群也是受此影响，各港口之间存在着恶性竞争，盲目投资建设等问题。将此影响产生的变化作为研究背景，以京津冀港口群的建设与港口运行效率为研究对象，为更好地了解京津冀港口群及各港口的效率运行情况,选取京津冀港口群及各个港口的输入指标和输出指标,利用数据包络分析法(DEA)分别对港口群和各港口效率进行测度。并利用港口协同发展理论与港口群的相关理论相结合，指出京津冀港口群投入过剩、重复建设和协同发展不协调等严重问题。最后从协同发展的角度提出促进京津冀地区各港口之间充分发挥各自的比较优势，错位发展、提高效率和理性建设的建议，从而提升整个港口群的竞争力，对京津冀港口群的长期可持续建设与发展具有重要意义。关键词：京津冀港口群，协同发展，DEA 本科论文AbstractWith the increasing level of social and economic development of the beijing-tianjin-hebei city cluster, the driving role of core cities on the surrounding areas is expanding, and the coordinated development of the beijing-tianjin-hebei region has achieved great results. At present, in order to continue to expand the strategic achievements of coordinated development, the three places have signed a series of new round of cooperation framework agreements to consolidate the cooperation at more levels. However, due to the great difference between the economic development of the peripheral cities and the core cities in the beijing-tianjin-hebei region, and the restriction and influence of the administrative system, the process of the integrated development of the beijing-tianjin-hebei region is slow. At the same time, the beijing-tianjin-hebei port group is also af...
