中文摘要：

＂一带一路＂共建的核心是经济,经济合作贸易先行。文章立足竞争与互补性的贸易治理分析框架,建立基于UNCOMTRADE数据库的出口相似度、贸易结合度、G-L、B-L和RCA指数模型,深入剖析中国与中亚区域贸易合作状况。研究发现,中国与中亚出口在欧美市场互补性日渐增强,在俄罗斯则有竞争性加强趋向;两地贸易结合度正越发紧密,相互逐步成为对方越发重要的贸易对象,呈现出强互补的产业间贸易特征;中国优势产品以制成品和机械运输设备类目为主,中亚则是矿物燃料和非食用原料,两地强势产品种类未有重叠,贸易潜力较强,合作空间广阔。＂一带一路＂倡议的提出,为中国与中亚加强经贸合作开辟了新的天地,区域具备了建立自由贸易区的有利条件,未来贸易合作有望不断升级。

英文摘要：

Economy is the core of the ＂Belt and Road＂ initiative and trade is the foremost in economic cooperation. This paper sets up the model of Export Similarity Degree, Trade Intensity Index, G-L Index, B-L Index and RCA Index based on the UNCOMTRADE database in the framework of competitive and complementary trade cooperation between China and Central Asia to thoroughly analyze their trade cooperation situation. It finds that the export from China and Central Asia seems increasingly complementary to Europe and the United States while it seems increasingly competitive to Russia. The results also show that since the inter-industry trade between China and Central Asia is obviously complementary, the trade between these two areas is combining more and more closely, which makes them become more important trade partners to each other. What＇ s more, the advantageous trading products in China are manufactured goods and machinery and transport equipment, while those in Central Asia are fossil fuels and non-edible raw materials. There is no overlap of their advantageous products, and their trade potential is strong to make broader cooperation, which reveals favorable conditions for establishing a free trade area. The ＂Belt and Road＂ initiative has opened a new world to strengthen the economic and trade cooperation between China and Central Asia,which forecasts the continuously upgrading of their bilateral trade cooperation.
