| 中文摘要: |
| 研究目标：探索基础设施投入对区域经济增长的多维影响。研究方法：运用永续盘存法非传统途径估算省际1993～2016年基础设施的生产性资本存量，再利用组内差分、空间计量等方法实证检验。研究发现：基础设施整体上显著促进区域经济增长，且存在倒“U”形影响，网络基础设施的产出弹性值已跃过“拐点”，而点基础设施仍处于上升期。基础设施的产出弹性值从高到低依次为西部、中部和东部地区。东部地区两类设施的产出弹性值较为接近，中部地区网络基础设施偏高，西部地区则点基础设施较高。基础设施整体和点基础设施都具有稳健负向溢出效应，网络基础设施在整体上具有正向溢出效应。工业集聚和就业增长是基础设施影响区域经济增长的重要传导渠道。研究创新：基于效率性、异质性和空间性的三维视角，捕捉基础设施在结构类型、发展阶段和区域配置间对区域经济增长的作用差异及传导机制。研究价值：为优化基础设施投资策略，实现经济高质量增长提供决策建议。 |

| Research Objectives: Exploring the multidimensional impact of infrastructure inputs on regional economic growth. Research Methods: The non-traditional approach of perpetual inventory method is used to estimate the inter-provincial productive capital stock of the infrastructure from 1993 to 2016, and then use the intra-group difference method and the spatial measurement method for empirical testing. Research Findings: Infrastructure as a whole significantly promotes regional economic growth, and there is an inverted “U” type effect. The output elasticity of network infrastructure has jumped beyond the “inflection point”, while the coefficient of point infrastructure is still rising. The output elasticity of infrastructure is from high to low in the west, central and eastern regions. The output elasticity values of the two types of facilities in the eastern region are relatively close, the network infrastructure in the central region is higher, and the infrastructure in the western region is higher. Both the infrastructure as a whole and the point infrastructure have a robust negative spillover effect, and the network infrastructure has a positive spillover effect as a whole. Industrial agglomeration and employment growth are important transmission channels for infrastructure to influence regional economic growth. Research Innovations: From the three-dimensional perspective of efficiency, heterogeneity and network input, capturing the difference in the role of infrastructure investment in regional economic growth between structure type, development stage and regional configuration and their transmission mechanisms. Research Value: Providing decision-making advice for optimizing infrastructure investment strategies and achieving high-quality economic growth. |
