税收努力度、公共支出规模与全要素生产率增长研究——基于内蒙古自治区101个旗县区的空间计量测度

Research on Tax Effort,Public Expenditure and Total Factor Productivity Growth——Spatial Econometric Measurement Based on 101 Counties in Inner Mongolia Autonomous Region

基于内蒙古自治区县级全要素生产增长率、税收努力度和公共支出规模数据,使用空间滞后模型分析税收努力度、公共支出规模对全要素生产率增长的影响。实证结果显示:内蒙古自治区101个旗、县、区全要素生产率之间体现出较强的空间相关性,税收努力对全要素生产率具有微小的贡献率,而公共财政支出规模具有较强的抑制效应。这说明一个地区实现经济高质量增长一定意味着全要素率增长提高与综合福祉水平的提升互为内生。制度改进、高储蓄率和技术创新是经济增长的源泉,但经济高质量增长的动能主要是技术进步,尤其是发展中地区供给管理的侧重点是技术原创新。

Based on the county-level data of total factor productivity( TFP) growth rate,tax effort and public expenditure,the Spatial Lag Model is adopted to analyse the influence of the latter two on the former. The empirical results show that there is a strong spatial correlation of TFP among the 101 counties in Inner Mongolia. Tax efforts have slightly positive contribution to the TFP,while public expenditure brings strong inhibition. The implication is that the high economic growth of a region only comes when the increase of the total factor growth rate and the improvement of its overall welfare are endogenous. Institutional improvement,technological advances,and a high savings rate are the sources of economic growth,but the momentum of high quality growth mainly lie in technological progress. The focus of supply management in developing regions must be technological innovation.
