【摘要】 本文利用2003-2013年全国284个地级及以上城市的统计数据,采用空间杜宾模型等空间计量经济学方法考察了科教支出对城市经济增长的空间溢出效应以及现代交通网络体系对其的影响,发现如下结论:第一,本地区科教支出不仅对本地经济增长具有促进作用,同时还具有空间溢出效应。第二,科教支出的空间溢出效应在不同阶段具有不同的表现形式。在2003-2008年间,本地区科教支出的增加会对邻近地区的经济增长产生积极的促进作用,而在2009-2013年间,本地区科教支出的增加则会对邻近地区的经济增长产生负向抑制作用。第三,科教支出的空间溢出效应会随着时空距离的增大而缩减,但随着现代交通体系的发展特别是高铁网络的发展,科教支出空间溢出效应的正向作用效果和在时空距离上的影响范围均有所扩大。最后,本文结合上述主要结论就如何促进中国城市经济高质量发展提出了相应的政策建议。更多还原

【Abstract】 The article investigates the spatial spillover effects of science and education expenditure on urban economic growth and the role of modern traffic network system in the effect based on the panel data of 284 cities in China from 2003 to 2013. It finds that the fiscal expenditure on science and education not only promotes local economic growth but also has spatial spillover effects. The spatial spillover effects of science and education expenditure have different forms in different periods. During the period from 2003 to 2008,the increase of fiscal expenditure on science and education in one region had a positive effect on the economic growth of neighbor regions. But during the period from 2009 to 2013,the spillover effect turned negative. The spatial spillover effects of science and education expenditure decrease with the increase of space-time distance. However,with the development of modern transportation system,especially the high-speed rail network,the range of space spillover effect of science and education expenditure have expanded. The article also puts forward some policy suggestions on promoting the high-quality development of urban economy.更多还原
