贸易开放是影响区域技术效率的重要因素。本文运用DEA分析方法对我国2001-2010年区域技术效率及其变化特征进行了分析并在此基础上利用30个省(市、自治区)的面板数据,运用DOLS方法从总体和地区分组两个层面分别考察了贸易开放对区域技术效率的影响。研究表明,总体样本中出口和FDI对区域技术效率均不具有促进作用,但进口对技术效率均具有正向影响;而在区域分组中,出口和进口对中部地区技术效率均具有促进作用。本文深入分析了上述现象的原因并得出相应的启示以资借鉴。
Trade liberalization is an important factor affecting the technical efficiency in the region. This article uses DEA analysis method to analyze the regional technical efficiency and its changing characteristics in our country from 2001 to 2010 and makes use of the panel data of 30 provinces (municipalities and autonomous regions) on this basis. By using DOLS method, Respectively examines the impact of trade liberalization on regional technical efficiency. The research shows that the export and FDI in the overall sample do not promote the regional technical efficiency, but the import has a positive effect on the technical efficiency. In the regional grouping, the export and import promote the technical efficiency in the central region. This paper analyzes in depth the reasons for the above phenomena and draws some corresponding suggestions for reference.
