本文基于2000-2013年的省级面板数据,设置三种空间权重矩阵,运用Lesage and Pace(2009)提出的空间回归偏微分方法,实证检验了我国信息化发展对区域经济增长的空间溢出效应。研究发现,中国省域经济增长存在显著的正向空间相关性,区域经济活动受其他与之相近空间特征地区的影响;三种空间权重下信息化对经济增长的区域内溢出效应显著为正,溢出效应在0.18-0.25之间,但区域间溢出效应并不显著;固定资产投资对经济增长具有直接的促进作用,但影响小于信息化的效应水平;人力资本在促进区域经济增长方面的作用尚未得到应有发挥,潜能需要进一步释放;政府财政支出对区域经济增长的正向间接效应抵消了负向直接效应,因而总效应表现为促进。 Based on the provincial panel data from 2000 to 2013, this paper sets up three kinds of spatial weight matrixes and applies the spatial regression partial differential method proposed by Lesage and Pace (2009) to empirically test the spillover effects of informatization development on regional economic growth. The study finds that there is a significant positive spatial correlation in the provincial economic growth in China and the regional economic activities are affected by other similar spatial characteristics in the region; under the three kinds of spatial weights, the intra-regional spillover effect of informatization on economic growth is significantly positive, The spillover effect is between 0.18-0.25, but the spillover effect between regions is not significant. Investment in fixed assets has a direct promotion effect on economic growth, but the impact is less than that of informationization. The role of human capital in promoting regional economic growth has not yet been They should be given full play and their potential needs to be further released. The direct indirect effect of government fiscal expenditure on regional economic growth offset the negative direct effect, and the overall effect is promoted.
