Abstract：Global warming and the accelerated melting of Arctic sea ice have made it possible to open the Arctic Route， and the shipping value of Arctic Route is becoming more prominent and has an important impact on the economic ties of countries along the route. In this paper， the gravity model and accessibility theory were used to analyze the spatial structure and network characteristics of the economic connection network of the Arctic Route Economic Circle， and the results are shown as follows. The opening of the Arctic Route promotes an increase in the node centrality of some nodes， and there is a significant core-periphery structure in the economic connection network of the Arctic Route Economic Circle. The opening of the Arctic Route also promotes the increase in the density of the economic connection network of the Arctic Route Economic Circle， and the connections among countries have gradually become more closer. After the opening of the Arctic Route， most Western European countries have high level of accessibility， and the level of accessibility of Northeast Asian countries have increased significantly， while the accessibility level of Northeast Asian countries are still low.
