【摘要】：随着我国经济的发展，煤炭作为基础能源的需求日益增大，越来越多的煤炭新增运输需求通过“北煤南运”的水路通道得以满足。我国主要煤炭港口作业压力日趋增大，煤炭港口通过能力不足的问题也日渐明显。在此环境下，黄骅港作为我做新兴能源港口得以飞速发展，近几年来黄骅港不断加快码头基础设计的建设，货物吞吐量连年保持15%以上的飞速上涨，但同时，港口船舶周转慢，滞留时间长的问题也渐渐显现出来，如何比较衡量自身的发展水平，了解资源使用情况，提高港口运营效率成为港口发展亟待解决的问题。本文为获取黄骅港的效率水平，使用数据包络模型对我国十个主要煤炭港口进行横向比较，以得到黄骅港的相对效率得分。在进行效率评价时，本文对数据包络模型进行了两点改进，通过引入虚拟决策单元和约束向量，使评价结果更客观、更有辨别度，弥补了类似研究中的不足。其次，本文建立评价模型时，从生产角度出发，以港口基础设施为投入，以港口吞吐量为产出，并结合煤炭港口的自身特点，将影响煤炭港口效率的港口自有铁路线长度、码头长度、堆场堆存容量、煤炭吞吐量等因素纳入了评价范围之内，弥补了类似研究都只针对集装箱港口的空白。本论文主要分为六章，第一章绪论分析了论文的研究背景、研究意义、对前人关于煤炭港口和港口效率的文献进行了综述；第二章简要地对比了几种港口效率评价方法，对数据包络分析方法进行了简单的介绍，并针对港口问题的研究对其进行了改进；第三章分析了黄骅港煤炭运输的主要市场背景，预测了我国煤炭海运需求，并对黄骅港和其竞争港口的基础设施和下水经济性做了比较。在第四章完成了指标的确定，并结合AHP层次分析法对输入指标、输出指标赋权重；第五章利用改进的DEA模型对我国十个煤炭港口进行效率，，得到黄骅港在煤炭港口中的相对效率，评价并分析效率得分结果；最后一章为结论和展望。
[Abstract]:With the development of our country's economy, the demand for coal as the basic energy is increasing day by day, more and more new coal transportation demand can be satisfied through the waterway passage of "North coal south transportation". Under this environment, Huanghua Port, as a new energy port, has been developing rapidly. In recent years, Huanghua Port has been speeding up the construction of wharf foundation design. The throughput of cargo keeps rising at a high speed of more than 15% year after year, but at the same time, the problems of slow turnover and long detention time of port ships are also gradually emerging. How to compare and measure the level of development and understand the use of resources, Improving the efficiency of port operation has become an urgent problem for port development. In order to obtain the efficiency level of Huanghua Port, this paper uses the data Envelopment Model to compare the ten main coal ports in China in order to get the relative efficiency score of Huanghua Port. In this paper, two improvements are made to the data envelopment model. By introducing virtual decision units and constraint vectors, the evaluation results are more objective and discernible, which make up for the shortcomings of similar research. Secondly, when the evaluation model is established, From the point of view of production, taking port infrastructure as input, port throughput as output, and combining the characteristics of coal port, the length of port's own railway line, the length of wharf and the storage capacity of yard will affect the efficiency of coal port. Factors such as coal throughput are included in the evaluation scope, which make up the blank of similar research only for container ports. This paper is divided into six chapters. The first chapter analyzes the research background and significance of the paper, summarizes the previous literatures on coal port and port efficiency, and briefly compares several methods of port efficiency evaluation. This paper briefly introduces the method of data envelopment analysis, and improves it for the study of port problems. Chapter three analyzes the main market background of coal transportation in Huanghua Port, and forecasts the demand of coal shipping in China. The comparison of infrastructure and water economy between Huanghua Port and its competing port is made. In Chapter 4th, the index is determined, and the input index and output index are weighted by AHP Analytic hierarchy process (AHP). In chapter 5th, the efficiency of ten coal ports in China is obtained by using the improved DEA model, and the relative efficiency of Huanghua Port in coal port is obtained, and the result of efficiency score is evaluated and analyzed. The last chapter is the conclusion and prospect.
