摘要
运用随机前沿引力模型,考察了2001~2018年间中国对中亚五国的农产品出口效率,并进一步构建出口非效率模型,对出口效率的影响因素进行了分析。结果表明:中国对中亚五国农产品出口的整体效率水平较低,但呈现出随时间递增的态势;中国与进口国之间的地理距离显著抑制了中国对中亚五国的农产品出口,中国及中亚五国的经济发展水平、中亚五国的市场需求规模显著促进了中国对中亚五国的农产品出口;上海合作组织框架、中亚五国的贸易自由度、金融自由度及基础设施水平在促进中国对中亚五国农产品出口效率提升方面作用明显。
Using the stochastic frontier gravity model,this paper investigated the export efficiency of China’s agricultural products to the five Central Asian countries during2001-2018,and constructed the export non-efficiency model to analyse the factors affecting export efficiency. The results show that China’s export efficiency to the five Central Asian countries is low,but it shows a trend of increasing with time;and the geographical distance between China and the countries has significantly inhibited China’s exports of agricultural products to the five Central Asian countries. The economic development level of China and the five countries,and the market demand scale of the five countries have significantly promoted China’s exports of agricultural products to them. The framework of the Shanghai Cooperation Organization,the degree of freedom of trade,financial freedom and infrastructure of the five countries promote China’s role in improving the efficiency of agricultural exports to them.
