新基建赋能高新技术产业的异质性影响研究——基于空间面板计量模型的实证检验

A Study on the Heterogeneous Impact of New Infrastructure Construction Empowering High-tech Industries——An Empirical Test Based on a Spatial Panel Econometric Model

新基建作为我国近年来重要的战略举措,尽管有助于推进新一代信息技术与制造业融合升级,但是在赋能高新技术产业的过程中仍存在一定的短板问题。为探究新基建对高新技术产业发展的异质性影响,本文对2013—2018年各省份新基建综合指数进行客观和系统评价,并运用空间面板计量方法对该影响机制实证分析。研究表明:(1)新基建对高新技术产业发展呈现“U型”影响。从短期看,当前新基建对高新技术产业发展产生抑制效应;从长期看,当新基建水平提升到一定阶段时,将赋能高新技术产业发展。(2)新基建的直接空间效应显著,空间溢出效应仍值得商榷,新基建的区域联通功能尚未完全发挥。根据研究结论,从推进新型基础设施联通、提升新基建赋能水平和打通新基建内在融合互动机制三个方面提出相应对策建议。

New infrastructure construction, as an important strategic initiative of China in recent years, still has certain shortcomings in the process of empowering high-tech industries, despite it can promote the integration and upgrading of a new generation of information technology and manufacturing. In order to explore the heterogeneous influence of the new infrastructure construction level on the development of high-tech industries, this paper objectively and systematically evaluates the level of new infrastructure construction in each province from 2013 to 2018, and empirically analyzes this influence mechanism using spatial panel econometric methods. The study shows that:(1) the level of new infrastructure construction has a “U-shaped” impact on the development of high-tech industries. In the short term, the current level of new infrastructure construction has a dampening effect on the development of high-tech industries;in the long term, when the level of new infrastructure construction reaches a certain stage, it will empower the development of high-tech industries.(2) The direct spatial effect of new infrastructure construction is significant, but the spatial spillover effect is still debatable, and the regional connectivity function of new infrastructure construction has not yet been fully played. Based on the findings of the study, corresponding countermeasures are proposed in three aspects: promoting new infrastructure connectivity, enhancing the level of new infrastructure empowerment and facilitating the inherent integration and interaction of new infrastructure.
