摘要
为了探究省会城市基础设施投资效率的水平、差异及影响因素,以中国省会城市2010—2022年的数据为基础,采用超效率SBM模型和Malmquist指数法测度基础设施投资效率与全要素生产率,并构建Tobit回归模型分析城市基础设施投资效率的影响因素。研究发现:基础设施投资效率高的区域有两个特征:一是高投入、高产出,这些城市人口集聚、经济发展和科技水平排在全国前列;二是低投入、高产出,这些城市规模大,发展迅速,产业结构以第二、三产业为主。规模效率对各区域的基础设施投资全要素生产率有显著正向影响,科学技术支出和人口密度对全国省会城市基础设施投资效率平均水平有显著正向影响。
To investigate the level,differences,and influencing factors of infrastructure investment efficiency in provincial capital cities,data from Chinese provincial capital cities from 2010 to 2022 was employed to apply the super efficiency SBM model and Malmquist index method to measure the efficiency of infrastructure investment and total factor productivity.A Tobit regression model was constructed to analyze the influencing factors of urban infrastructure investment efficiency.The findings indicate that regions with higher efficiency in infrastructure investment exhibit higher input and output.These cities are among the most populous,economically developed,and technologically advanced in the country.In contrast,other regions with higher efficiency exhibit lower input and higher output.These cities are large in scale,experiencing rapid growth,and their industrial structure is primarily composed of the secondary and tertiary industries.The scale efficiency of infrastructure investment has a significant positive impact on the total factor productivity of infrastructure investment in various regions.The expenditure on science and technology,as well as population density,have a significant positive impact on the average efficiency of infrastructure investment in provincial capital cities across the country.
