运用空间计量的研究方法,引入地理权重和经济权重矩阵,采用我国各省域2001—2012年的样本数据,对政府采购规模的增长效应开展研究。通过研究得出与传统研究相悖的结论:人均GDP对政府采购规模增长贡献并不显著,而投资作为政府采购规模的重要解释变量有着良好的空间溢出效应;城镇化存在巨大的示范效应,对邻接区域政府采购规模增长的空间溢出效应显著。最后,提出促进政府采购增长与合理配置、提高政府采购资源利用效率的政策建议,尤其是探讨了其在政府和社会资本合作模式下的政策建议。
By using the method of spatial measurement, we introduce the geographic weight and economic weight matrix, and use the sample data from 2001 to 2012 in all provinces of our country to study the growth effect of government procurement scale. Through the research, it is concluded that the per capita GDP does not contribute significantly to the growth of government procurement scale, while the investment as an important explanatory variable of government procurement scale has a good spillover effect. There is a huge demonstration effect of urbanization on the adjacency The spillover effect of regional government procurement scale is remarkable. Finally, it puts forward some policy recommendations to promote the growth and rational allocation of government procurement and improve the efficiency of government procurement. In particular, it discusses its policy recommendations in the mode of government and social capital cooperation.
