超大型深水航道航运经济效益分析及相关问题探讨——以2012年度长江口深水航道航运经济效益为例

The Correct Calculation and Analysis of Navigation Economic Benefit of Ultra-Large Deepwater Channel——The Yangtze Estuary 12.5 m Deepwater Channel as an Example

摘要: 目前，对于长江口深水航道这样世界级的复杂和超大型的深水航道，治理后实际所产生的经济效益增量的分析尚无成熟的方法，许多传统的航道经济评价和分析方法已不适应。为使长江口深水航道治理后的航运经济效益分析尽量与实际情况相符，本文在许多方面作了探索和尝试，希望能为该类研究提供借鉴。

Abstract: As a number of evaluation methods have already not been suitable, currently, it is hard to find a set of mature methodologies to evaluate the economic added value due to the introduction of measurements to improve the complicated situation of the deep water channel of the Yangtze Estuary 12.5 m Deepwater Channel. In order to keep the analysis result of economic efficiency in line with the real situation after the improvement of the deep water channel project, this paper is expected to provide some evidences for relevant research through explorations and attempts conducted by the author.
