中文摘要：

俄、白、哈关税同盟是欧亚经济共同体框架内区域经济一体化重要的阶段性成果，本文重点分析了该关税同盟的贸易效应：2011—2012年，同盟成员国之间的贸易增幅远高于成员国与其主要贸易伙伴的贸易增速，除了哈萨克斯坦之外，俄罗斯、白俄罗斯与同盟成员国的贸易在其外贸总额的占比均有所上升，说明关税同盟促进了三国贸易往来。虽然关税同盟的运行导致了中国对哈国出口成本增加，但由于俄、哈两国与中国属于互补型贸易关系，中国与各成员国的双边贸易仍呈现快速增长状况，俄罗斯加入WTO将促进中俄双边经贸合作规范化和稳健化发展。

英文摘要：

Russia - Belarus - Kazakhstan Customs Union is one of the important achievements for the Eurasian Economic Community＇s economic integration. This essay emphasizes on the trade effect of this Customs Union. The study shows that the trade growth between the Customs Union member states is much higher than that with its main trading partners. The percentage of Russia and Belarus＇s trade with its Customs Union member states accounting for its total amount of foreign trade is rising besides Kazakhstan. Customs Union leads to increased cost for China＇s export to Kazakhstan, but there is no great impact on China＇s trade with Russia and Kazakhstan, becuase Russia and kazakhstan are complementary trade relations with China. Russia＇s entry into WTO, will promote the specification and robustness development of bilateral economic and trade cooperation between China and Russia.
