Abstract
作为新发展阶段中国基础设施建设的重点,"新基建"能否提升区域经济韧性是一个有待回答的重要问题.基于2015-2019年的省级面板数据,从抵抗恢复、适应调整和创新转型三个方面明确了区域经济韧性的内涵,并构建指标体系测度了研究时段内各省份"新基建"发展情况,在此基础上,进一步运用固定效应模型和中介效应模型检验了"新基建"对区域经济韧性的影响和作用机制.研究表明:"新基建"显著提升了区域经济韧性,并且这一效应在经过替换被解释变量、工具变量回归等一系列稳健性检验后依然成立.机制检验结果显示,"新基建"通过加强区域一体化、促进产业转型升级和激发创新活力间接发挥赋能效果.异质性分析结果显示,相较于融合基础设施,5G等新型信息基础设施对区域经济韧性发挥了更大的赋能作用;相较于沿海地区,"新基建"对内陆地区经济韧性的提升作用相对更大.此外,空间计量回归结果显示,在不同的权重矩阵设定下,"新基建"对于区域经济韧性的间接效应均显著为正,即"新基建"对于地理相邻区域及经济发展水平相近区域的经济韧性都有着显著为正的空间溢出效应.
As the focus of China's infrastructure construction in the new stage of development,whether"new infrastructure"can enhance regional economic resilience is an important question to be answered.This paper fills the research gap on the impact of"new infrastructure"on regional economic resilience,and provides evidence on how"new infrastructure"can promote regional economic resilience from both theoretical and empirical aspects.Based on the provincial panel data from 2015 to 2019,this paper clarifies the connotation of regional economic resilience from three aspects:resistance recovery,adaptation and adjustment,innovation and transformation,and constructs an index system to measure the development of"new infrastructure"in each province during the study period.The results show that"new infrastructure"significantly improves regional economic resilience,and this effect is still valid after a series of robustness tests such as replacing the explanatory variables and the regression of instrumental variables.The mechanism test results show that"new infrastructure"indirectly exerts enabling effects by strengthening regional integration,promoting industrial transformation and upgrading,and stimulating innovation vitality.The heterogeneity analysis results show that compared with the new converged infrastructure,new information infrastructure,such as 5G(the 5th generation mobile networks),has played a greater enabling role in regional economic resilience.Compared with the provinces in the coastal areas,"new infrastructure"has a relatively greater effect on improving the economic resilience of the provinces in the inland areas.In addition,the results of spatial econometric regression show that under different weight matrix settings,the indirect effect of"new infrastructure"on regional economic resilience is significantly positive,that is,"new infrastructure"has a significantly positive spatial spillover effect on the economic resilience of geographic-ally adjacent regions and regions with similar economic development levels.
