引力模型在服务贸易流量研究中的应用:国内外研究述评与展望

Literature Review on the Application of Gravity Model in Service Trade Flows Research

改善中国服务出口的地区市场结构对促进中国服务贸易的发展具有重要作用,而引力模型在该领域的研究中具有重要的意义和前景。本文从引力模型在服务贸易领域的适用性、修正和扩展引力模型的解释变量、改进引力模型的估计方法、特定因素对服务贸易的影响等方面对国内外的相关文献进行了系统的梳理和评述,以把握其目前动态,从而为后期的相关研究提供参考和借鉴。

Improving China’s service export market structure plays an important role in promoting the de-velopment of China’s service trade. In this field of study, gravity model has important significance and prospect. Based on the applicability of gravity model, the correction and expansion of explan-atory variables of gravity model, the improvement of estimation method of gravity model, the spe-cific factors of impact on trade in services and so on, the paper systematically reviews the related literature at home and abroad, so as to master the latest development and provide references for later research.
