河南省沿黄八市生态经济效率测评及分异研究

Research on Evaluation and Differentiation of Eco-Economic Efficiency in Henan’s Yellow River Economic Belt

河南省跨越黄河中游和下游,是中原经济区的主体,在国家经济建设中居于承东启西的重要地位,河南省沿黄经济带的高质量发展事关整个黄河流域生态保护和高质量发展。为了给河南省及其沿黄经济带的经济高质量发展乃至整个黄河流域高质量发展提供参考,运用Super-SBM模型和Malmquist指数、莫兰指数等,对河南省及沿黄八市生态经济效率进行测评并分析其时空分布特征和演变规律。结果表明:2007—2017年,河南省生态经济效率从0.831波动上升到0.921,目前仍没有达到全效率水平,即生态经济资源配置存在不合理的情况,生态经济建设有待加强;沿黄八市生态经济效率差别较大,除洛阳市外都表现出上升态势;河南省生态经济全要素生产率呈上升趋势,在沿黄八市中济源和郑州市的生态经济全要素生产率变化较为平稳、Malmquist指数在1.0上下小幅波动,而其他六市生态经济全要素生产率波动相对较大、Malmquist指数分别在2009—2010年和2015—2016年出现较大峰值;从空间分布差异来看,河南省各市生态经济效率差异逐渐缩小,其全局空间相关性在2007年较弱、在2017年则进一步弱化为随机分布,小部分城市表现出集聚特征。

Crossing the middle and lower reaches of the Yellow River,Henan Province is the main body of the Central Plains Economic Zone.It plays an important role in the national economic construction and the high-quality development of Henan Province along the Yellow River economic belt is related to the ecological protection and high-quality development of the entire Yellow River Basin.In order to provide a reference for the high-quality economic development of Henan Province and its economic belt along the Yellow River and the high-quality development of the entire Yellow River Basin,the super-efficiency Super-SBM model,Malmquist index and Moran index were used to evaluate the eco-economic efficiency of Henan Province and the eight cities along the Yellow River and analyze the temporal and spatial distribution characteristics and evolutionary laws.The results show that the eco-economic efficiency of Henan Province fluctuates from 0.831 to 0.921 from 2007 to 2017 and it has not yet reached the full efficiency stage,that is,the allocation of ecological economic resources is unreasonable and the construction of ecological economy needs to be strengthened;the eco-economic efficiency of the eight cities along the Yellow River are quite different,with the exception of Luoyang City showing an upward trend;the total factor productivity of the ecological economy of Henan Province is on the rise and the total factor productivity of the ecological economy in the eight cities along the Yellow River in Jiyuan and Zhengzhou has changed relatively smoothly,the Malmquist index fluctuates slightly around 1.0,while the other six cities have relatively large fluctuations in the total factor productivity of the ecological economy,the Malmquist index has a large peak in 2009-2010 and 2015-2016 respectively;from the perspective of differences in spatial distribution,the differences in eco-economic efficiency of cities in Henan Province are gradually narrowed,the global spatial correlation is weak in 2007 and is further weakened to random distribution in 2017 and a small number of cities show agglomeration characteristics.
