摘要
从碳排放约束视角出发,利用Super-SBM模型和Malmquist指数对2005—2019年我国30个省份基础设施投资效率分别进行了静态和动态评价,分析了影响投资效率变化的外部因素。结果表明:①静态特征上,我国基础设施投资效率呈波动上升趋势,各省份效率逐渐形成“低低集聚、高高集聚”的近“双峰”式演变格局。②动态特征上,我国基础设施全要素生产率呈倒“U”型发展态势,区域层面呈现出“东部>中部>东北>西部”的发展特征。③影响因素上,能源强度对东北和中西部地区效率产生消极影响;技术创新促进了东北和西部地区效率提升;政府支出和金融效率对中西部影响显著为正。结合研究结论,提出促进我国基础设施可持续发展建议。
From the perspective of carbon emission constraints,this paper used Super-SBM model and Malmquist index to evaluate the static and dynamic efficiency of infrastructure investment in 30 provinces in China from 2005 to 2019,and analyzed the external factors influencing efficiency changes.The results showed that:①The static efficiency of national infrastructure investment presented a fluctuating upward trend during the research period.At the regional level,efficiency gradually formed a nearly“double peak”evolution pattern of low-low and high-high concentration.②The dynamic efficiency of national infrastructure investment showed an inverted“U”shape trend,and the regional level showed a trend of“East>Central>Northeast>Western”.③Energy intensity had a negative impact on efficiency in Northeast,Central and Western China.Technological innovation promoted investment efficiency in Northeast and Westenr China.The impact of government expenditure and financial efficiency on the efficiency of central and Western China was significantly positive.Finally,this paper put forward some suggestions for sustainable development of infrastructure in China.
