绿色复苏视角下“新基建”如何推进高技术产业创新能力提升?

HOW CAN “NEW INFRASTRUCTURAL CONSTRUCTION” BOOST HIGH-TECH INDUSTRIAL INNOVATION CAPABILITIES FROM PERSPECTIVE OF GREEN RECOVERY?

当前碳排放即将达到峰值,自然资源制约等问题日益突出,同时疫情冲击与科技产业变革也不容忽视,发挥“新基建”(新型基础设施建设)绿色赋能效应的必要性毋庸置疑。高技术产业具有技术知识密集、低资源消耗、低污染等特点,其创新能力能够体现产业的进步,同时推动经济社会向集约环保型发展方式转变。论文以绿色复苏为视角,梳理了“新基建”对高技术产业创新能力的影响的内在理论机制,这对于科学合理地引导“新基建”的投入与使用,使之成为绿色发展、产业创新的重要手段具有重要的实践意义。基于2008—2020年中国28个省级面板数据,首先运用基准回归模型研究“新基建”对高技术产业创新能力提升的影响,并通过变量替换进行稳健性检验;其次对我国东中西部区域进行回归分析;最后采用中介效应模型,对“新基建”是否会通过成本节约效应、溢出效应及人力资本效应促进高技术产业创新进行考察。研究结果表明:1)整体来看,“新基建”能够显著提升高技术产业创新能力,在使用不同衡量指标进行稳健性分析后,该结论依然成立;2)从地域划分看,东部地区“新基建”对高技术产业创新能力提升起促进作用,而中部和西部地区的作用则不显著;3)人力资本效应是“新基建”推动高技术产业创新能力提升的重要渠道,成本节约效应存在遮掩效应,而溢出效应并不显著。经研究得出:我国应持续鼓励“新基建”发展,同时发挥政府的引导作用,因地制宜推进东中西部的“新基建”投资进程,畅通“新基建”对高技术产业创新能力提升的传导路径,使“新基建”成为助推经济发展、生态可持续、产业创新进步的利器。

Currently it has not doubt to exert green empowering effect of“New Infrastructural Construction”to confront the upcoming carbon peaking,constraints of natural resources,Co-VID19 s impacts and technical industrial reform.High-tech industry is of intensive knowledge,low resource consumption and low pollution,its innovative capabilities can embody industrial advances and help convert economy to an intensive and environment-friendly mode.This paper,viewing from green recovery,studies the theoretical mechanism of“new infrastructural construction”on high-tech industrial innovation.Inputs and use of“new infrastructural construction"as a vital means of green development and industrial innovation matters.This paper,based on China s 28 province s 2008 to 2020 panel data,uses baseline regression model to study impacts of“new infrastructural construction”on high-tech industrial innovative capabilities which has been validated by stability test through replacement of variables.Regression analysis is also conducted on China s east and west.Mediating effect model is applied to study the impacts of cost saving effect,overflow effect and human capital effect on high-tech industrial innovation.Overall,“new infrastructural construction”can improve high-tech industrial innovative capabilities,outstandingly in eastern China little in central and western China.Human capital effect is an important path to improving high-tech industrial technical innovative capabilities in“new infrastructural construction”,but cost saving effect has a little overflow due to its masking effect.It concludes that China should support“new infrastructural construction”,exerts governmental leading role in advancing investment in central and western China,makes“new infrastructural construction”a path to high-tech industrial innovative capabilities,which is key to economic development,ecological sustability and industrial innovation.
