建立了国家贸易势力模型,并测度了相邻各国贸易势力指数,分析了本地区贸易均势现状。研究显示:泛天山地区各国贸易势力都比较弱,与贸易大国的差距十分明显。与中亚地区地缘的邻近性、经济的互补性以及民族的相通性决定了新疆在我国向西开放战略中不可替代的重要地位。从可持续发展理念来看,同邻国的经济贸易应遵循合作博弈原则,这也是大西北乃至全国经济可持续发展的重要保障。 Established a model of national trade forces, measured the index of trade forces in neighboring countries and analyzed the status quo of the trade balance in the region. The research shows that all countries in the Pan-Tien-Shan region have relatively weak trade forces and the gap with the big trading nations is very clear. Its geographical proximity with Central Asia, its complementarity with the economy, and its interdependence with each other determine the irreplaceable role of Xinjiang in China’s strategy of opening to the west. Judging from the concept of sustainable development, the economic trade with neighboring countries should follow the principle of cooperative game, which is also an important guarantee for sustainable economic development in the Greater Northwest China and the whole country.
