In order to further study the economic benefits of LNG ship through the Northeast Passage, combining the supply and demand of natural gas in China, the economic benefits of LNG ship through the Arctic Northeast Passage and the traditional route were compared based on the analysis of the navigable status of the Northeast Passage and the Arctic resources. The ship operation index, ship economic index and ship investment index were selected to construct the comprehensive evaluation index system of ship economic benefit. The entropy weight method was used to evaluate the weights of the evaluation indexes, and a LNG ship economic benefit evaluation model based on entropy weight method was established. The economic benefits of 8 ships with 125 thousand m3~160 thousand m3 LNG capacity were demonstrated and compared with the results of principal component analysis. Results show that the comprehensive economic benefit of the LNG ship with navigable capacity of 140 thousand m3 is the best. Entropy weight method can make a scientific evaluation of the economic benefits of LNG ships, which provides a feasible evaluation method for the economic benefit evaluation of LNG ships through the Arctic Northeast Passage.
Key words： Northeast Passage; entropy method; LNG ship; economic benefit evaluation
