摘　　要：为给黄河流域生态保护和高质量发展战略的实施提供参考,以黄河流域九省(区)为研究对象,将高质量发展作为切入点,以2009—2017年的空间面板数据为基础,运用三阶段DEA模型、Malmquist⁃DEA模型和绝对β收敛检验模型测算黄河流域绿色经济效率并进行收敛性分析。结果表明:黄河流域绿色经济效率整体偏低,各省(区)绿色经济效率存在明显差异,忽略外部环境因素和随机干扰的影响在一定程度上会高估黄河流域绿色经济效率;影响黄河流域绿色经济效率的外部环境因素具有多元性和复杂性,其中人均GDP和城镇化率的提高无助于绿色经济效率的提升,一般财政预算支出占GDP的比重、农林牧渔业和采矿业固定资产投资额占全社会固定资产投资额的比重的提高有助于绿色经济效率的提升;黄河流域整体绿色经济效率呈现衰减态势,技术进步变动指数衰减是导致流域绿色经济效率衰减的主要原因;黄河流域绿色经济效率具有收敛趋势,综合体现在纯技术效率收敛和规模效率收敛两方面。In order to provide reference for the implementation of ecological protection and high⁃quality development strategy in the Yellow River Basin,taking the nine provinces(regions)in the Yellow River Basin as the research object and high⁃quality development as the start⁃ing point,from the perspective of promoting high⁃quality development,this paper used three⁃stage DEA model,Malmquist DEA model and absoluteβconvergence test model to calculate the green economic efficiency of the Yellow River Basin and analyzed the convergence based on the spatial panel data from 2009 to 2017.The results shows that the overall efficiency of green economy in the Yellow River Basin is low,and there are obvious differences in the efficiency of green economy in all provinces and regions;ignoring the influence of external environmental factors and random interference,it will overestimate the efficiency of green economy in the Yellow River Basin;the external environmental factors affecting the efficiency of green economy in the Yellow River Basin are diverse and complex,and the improvement of per capita GDP and urbanization rate is helpless for improving the efficiency of green economy,the proportion of general budget expenditure in GDP is condu⁃cive to improve the efficiency of green economy,and the proportion of fixed assets investment in agriculture,forestry,animal husbandry,fishery and mining industry will help to improve the efficiency of green economy;caused by the decline of technological progress change in⁃dex,the overall green economic efficiency of the Yellow River Basin is declining;the green economic efficiency of the Yellow River Basin has the trend of convergence,which is reflected in the convergence of pure technical efficiency and scale efficiency.
