黄河流域三大城市群工业绿色全要素生产率评价

Evaluation of Industrial Green Total Factor Productivity in Three Urban Agglomerations in the Yellow River Basin

选择黄河流域呼包鄂榆、关中平原和中原城市群,基于超效率SBM-DEA与Malmquist-Luenberger模型对1998—2017年期间工业绿色全要素生产率(GTFP)进行评价,并从城市群与优势产业两个角度对驱动因素进行分析,并提出工业GTFP提升对策建议。结果表明:(1)研究区整体工业GTFP年均增速为16.5%,呈现波动上升趋势,各城市群时序变化特征差异显著;整体空间上GTFP值由中部关中平原城市群高转变为东南部中原城市群高。(2)技术进步是各城市群工业GTFP提高的主要驱动因素,城市优势产业对工业GTFP的驱动作用存在明显差异。最后提出升级技术创新能力、提高工业结构层次、因地制宜地制定差异化转型措施等对策建议。

This study selected three urban agglomeration,including Hohhot-Baotou-Ordos-Yulin,Guanzhong Plain and Central Plains.Based on the super-efficient SBM-DEA and Malmquist-Luenberger models,we evaluate the spatial and temporal variation characteristics of Green Total Factor Productivity(GTFP)during 1998—2017,and analyze the driving factors from two perspectives of urban clusters and dominant industries,and propose countermeasures.The results show that∶(1)The overall annual industrial GTFP growth rate in the study area was 16.5%,showing a fluctuating upward trend,and the temporal variation characteristics of each urban agglomeration were significantly different;the overall spatial GTFP value has shifted from being higher in the Guanzhong Plain urban agglomeration to being higher in the Central Plains urban agglomeration.(2)Technological progress is the main driver of the overall GTFP improvement in the study area,and there are obvious differences in the driving role of urban dominant industries on GTFP.Finally,countermeasures such as upgrading technological innovation capacity,improving the level of industrial structure,and formulating differentiated transformation measures according to local conditions are proposed.
