出口产品向量空间权重矩阵构造及扩展边际空间效应分析——基于俄罗斯农产品进口市场的实证研究

Spatial Weights Matrix Construction and Space Effects Analysis on Extensive Margin——An Empirical Test Based on Import Agricultural Market in Russia

空间计量经济学通过分析变量的空间效应来揭示区域经济发展规律。本文通过构造出口产品向量空间权重矩阵,选取20个国家对俄罗斯农产品出口的2007-2013年HS-6分位数据,结合传统的引力模型对俄罗斯农产品市场进行实证分析。实证结果表明,基于"出口产品向量空间权重矩阵"的空间引力计量模型提高了传统的引力模型在空间效应方面的解释能力。扩展边际不但与本国生产力等因素有关,从空间上,也与周边国家出口产品集相似度有关。

Spatial econometrics is used to analyze the regional economic development.The model used to do empirical testing is based on unit vector weights matrix,with HS6 digits data exporting to Russia’s agricultural market from 20 countries from 2007 to 2013.We find our model explains well the spatial effects on extensive margin,extensive margin related to not only productivity,also the similarity of products space set.
