中文摘要：

笔者采用因子分析法测算＂一带一路＂沿线西部省份2003年~2013年的经济开放度,并采用DEA包络线分析西部各省开放型经济运行效率,发现其总体经济开放度低于全国平均水平,部分省份经济开放程度与运行效率脱节,开放度受经济水平、基础设施、国家政策等因素影响较大。为此,＂一带一路＂沿线西部省份应该加强基础设施建设,以重点省市为核心发展城市群,重点扶持落后省份,注重开放的提质增效。

英文摘要：

By using factor analysis method,this paper measures the economic opening degree of the western provinces along the ＂One Belt and One Road＂over the period of 2003 – 2013. Then this paper estimates the operational efficiency of the opening economy of each western province through DEA envelope analysis. It is found that the overall economic opening degree of these western provinces lags behind the national average. Furthermore,the economic opening and the operational efficiency of some provinces are disjointed. In addition,the economic opening degree is mainly influenced by factors such as economic level,infrastructure and national policies. To this end,the western provinces along the ＂One Belt and One Road＂should strengthen infrastructure construction,develop urban agglomeration centered on key provinces and cities,focus on supporting backward provinces and pay attention to increasing the quality and the efficiency of openness.
