摘要
本研究基于黄河流域11个主要城市2008—2017年的面板数据,运用SBM-Undesirable模型和Malmquist指数模型对各城市绿色发展效率进行测算和分解,从时空维度和动静结合角度对黄河流域城市绿色发展进行分析。结果表明:①黄河流域总体绿色发展水平呈“V”型变化趋势,绿色发展效率不高,近年呈上升趋势;②流域整体技术效率和技术进步指数较低,需要加大科学技术创新投入,提高技术创新能力;③分城市看,区域分异空间格局明显,中下游城市绿色发展效率远高于上游城市,经济发展基础好的城市绿色发展效率高于经济基础薄弱的城市。
Based on the panel data of 11 major cities in the Yellow River Basin from 2008 to 2017,this paper uses SBM undesirable model and Malmquist index model to measure and decompose the green development efficiency of each city,and analyzes the urban green development of the Yellow River Basin from the perspective of space-time dimension and dynamic static combination.The results show that:1)the overall level of green development in the Yellow River Basin presents a V-shaped change trend,and the green development efficiency is not high,which shows an upward trend in recent years;2)the overall technical efficiency and technological progress index of the basin are relatively low,so it is necessary to increase the investment in scientific and technological innovation and improve the technological innovation ability;3)in terms of cities,the spatial pattern of regional differentiation is obvious,and the green development efficiency of the middle and lower reaches cities is far higher than that of the middle and lower reaches cities.The green development efficiency of cities with good economic development foundation is higher than that of cities with weak economic foundation.
