长江经济带“4E”协调发展时空格局研究

Spatio-temporal Pattern of ‘Four-E' in the Yangtze River Economic Zone

利用综合评价法和耦合协调模型对长江经济带经济发展、生态保护、能源建设和教育质量及其协调发展的时空格局进行分析。研究表明:2003~2014年间长江经济带经济发展指数、生态保护指数、能源建设指数与教育质量指数持续上升,其中经济发展指数增长最为明显;4E综合发展水平、耦合度和协调度均呈现上升趋势,4E协调发展模式由中心聚集向均衡化发展转变。根据研究结论提出加快传统经济向绿色经济发展转型、提高资源环境的生态承载力、降低单位GDP的能源消耗量和提升科技成果的经济转化率的发展建议。

Economy, ecology, energy and education （＇Four-E＇） are essential elements for promoting regional coordinated development. Construct the comprehensive evaluation index system of 4E in the Yangtze River Economic Zone, comprehensively evaluates the spatial pattern of economic development, ecological protec- tion, energy construction and educational quality of the Yangtze River Economic Zone from 2003 to 2014, and establish the coupling coordination evaluation model, analysis the temporal and spatial evolution trend of 4E coordinated development. Results show that： In 2003, the spatial pattern of ecological protection index of the Yangtze River Economic Zone was that the midstream area higher than the downstream area higher than the upstream area. From 2003 to 2014, the ecological protection index of the downstream areas increased rapidly, upstream area of energy construction and education quality index surpassed than the midstream area. In 2014, the spatial pattern of ecological protection index was that the downstream area higher than the area midstream area higher than the upstream area, the spatial pattern of energy construction and education quality index changed into the downstream area higher than the upstream area higher than the midstream area. In 2003, the spatial pattern of 4E in Yangtze River Economic Zone was the ecological protection index higher than the eco- nomic development index higher than the energy construction index higher than the education quality index. From 2003 to 2014, the economic development index, ecological protection index, energy construction index and education quality index of the Yangtze River Economic Zone continued to rise, which the economic devel- opment index growth is most obvious, ecological protection and energy construction, education quality growth rate was basically fiat. In 2014, the spatial pattern of 4E turned to economic development index higher than the ecological protection index higher than the education quality index higher than the energy construction index. From 2003 to 2014, the 4E coordination index of the Yangtze River Economic Zone showed an upward trend, the coordinated development model of 4E changed from the center gather towards equalization. At the end of this article, some suggestions are put forward, such as accelerate the transformation of traditional economy to green economy, improving the ecological carrying capacity of resources and environment, reducing the energy consumption per unit of GDP and increasing the economic transformation rate of scientific and technological achievements.
