Abstract: As an important part of Arctic routes, compared with Northwest Passage, Northeast Passage has a greater value to our country, and it has huge impact on economic development, marine trade, and port scale etc. Therefore, based on summing the close contact of shipping routes and port scale, the paper refers Bohai sea ports as the research object, and mainly analyses the impact Northeast Passage has on the cargo throughput, container throughput and operational efficiency for Bohai ports. Then the paper deeply analyses the comprehensive scores before and after the opening of Northeast Passage with principal component analysis, indicating that the opening will not break the current stage of Flying Geese Model of Bohai sea ports, but the development order for different ports will change in the same level. So, in response to this situation, the paper puts forward different development proposals to these ports.

Key words: Northeast Passage, port scale, Flying Geese Model
