摘要
利用考虑非期望产出SE-SBM模型测算黄河流域77个地级市2010—2020年工业绿色水资源效率,并借助修正引力模型以及社会网络分析法对效率空间网络关联结构特征进行综合评估。结果表明:①黄河流域工业绿色水资源效率呈现“下游>中游>上游”格局,局部动态性特征与非均质性特征并存。②黄河流域内部网络密度呈现自下游到中游再到上游逐级降低的态势。③工业绿色水资源效率空间关联板块间并未形成良好的循环传递框架。工业绿色水资源效率网络k-核结构呈现金字塔分布特征,且子群城市区位指向与择优特征明显,不利于缩小城际间发展差距。
To accelerate the improvement of the efficiency of industrial green water resources can effectively alleviate the biggest contradiction between ecological protection and high-quality development in the Yellow River Basin,and can also solve its biggest problem.The SE-SBM model considering unexpected output is used to calculate the industrial green water resource efficiency of 77 prefecture level cities in the Yellow River basin,and the characteristics of the spatial network correlation structure of efficiency are comprehensively evaluated by using the modified gravity model and social network analysis method.The results show that:1)The efficiency of industrial green water resources in the Yellow River basin has been significantly improved as a whole.The internal efficiency of the basin presents a pattern of"downstream>midstream>upstream".The local dynamic characteristics and heterogeneity characteristics coexist,and the horizontal difference of efficiency in the basin has expanded significantly.2)The internal network density of the Yellow River basin is significantly different from the regional network linkage development,showing a gradual decline from the lower reaches to the middle reaches and then to the upper reaches.3)The node characteristics of industrial green water resource efficiency network in the Yellow River basin are obviously regional heterogeneity,and the four level network has become the basic framework of the industrial green water resource efficiency network in the Yellow River basin.4)The spatial correlation plate of industrial green water resource efficiency is specifically divided into two-way spillover,net spillover,broker and net beneficiary plates,but a good circular transmission framework has not been formed between the plates.The K-core structure of the industrial green water resource efficiency network shows a pyramid distribution feature,and the sub cluster cities have obvious location orientation and preference characteristics,which is not conducive to narrowing the development gap between cities.
