摘要
利用2007—2019年国家高新区及中国城市数据,实证考察了“成熟型”和“成长型”高新区创新能力对城市全要素生产率的影响。研究发现:总体上,高新区创新能力的提高有助于城市全要素生产率(total factor productivity,TFP)增长,“成熟型”高新区创新能力对城市TFP存在抑制作用,“成长型”高新区创新能力对城市TFP有显著促进作用。中介效应检验表明:“成熟型”国家高新区创新能力通过促进城市产业结构升级对城市TFP的影响产生了遮掩效应;“成长型”高新区创新能力通过增强城市劳动力素质促进城市TFP增长。异质性检验显示:东部地区“成熟型”高新区创新能力对城市TFP有显著负面影响,而中西部地区“成熟型”创新能力能显著促进城市TFP提升。不同政府规模城市的高新区创新能力对城市TFP亦有不同影响。
Based on the data of national high-tech zones and Chinese cities from 2007 to 2019,the impact of the innovation capacity of“mature”and“growing”high-tech zones on urban total factor productivity has been empirically investigated. The research finds that,on the whole,the improvement of the innovation ability of high-tech zones contributes to the growth of urban TFP. The innovation ability of“mature”high-tech zones inhibits urban TFP,and the innovation ability of“growing”high-tech zones significantly promotes urban TFP. The intermediary effect test shows that the innovation ability of“mature”national high-tech zones has a masking effect on the impact of urban TFP by promoting the upgrading of urban industrial structure;The innovation ability of“growing”High-tech Zone promotes the growth of urban TFP by enhancing the quality of urban labor force. The heterogeneity test shows that the innovation ability of“mature”high-tech zones in the eastern region has a significant negative impact on urban TFP,while the“mature”innovation ability in the central and western regions can significantly promote the improvement of urban TFP. The innovation ability of high-tech zones in cities with different government scales also has different effects on urban TFP.
