    摘要:

    数字经济与经济的耦合协调发展对区域整体发展具有重要意义。通过构建数字经济与经济发展综合水平评价指标体系,运用耦合协调度模型和探索性空间数据分析方法,分析2011—2018年长江经济带98个城市数字经济与经济发展的耦合协调度及其空间相关性。研究表明:①长江经济带数字经济与经济发展水平均呈现上升趋势,且数字经济水平增速大于经济发展水平;二者均存在空间差异性,下游城市的数字经济与经济发展整体水平均相对较高,上、中游则与之相反。②长江经济带耦合协调度呈现稳步上升态势,整体耦合协调水平实现了轻度失调向初级协调转变;耦合协调度存在明显的空间差异性,呈现下游>中游>上游的整体趋势。③耦合协调度呈现正向空间自相关性,但随时间推移,空间自相关性减弱;耦合协调度的“高-高”集聚区域整体变动不大,“高-低”集聚区域呈现先扩大后缩小的分布状态,“低-低”集聚区域保持下降趋势。

    Abstract:

    The coupled and coordinated development of digital economy with the economy is of great significance to the overall development of the region. By constructing an evaluation index system for the comprehensive level of digital economy and economic development, using the coupling coordination degree model and exploratory spatial data analysis methods, the coupling coordination degree and its spatial correlation of digital economy and economic development in 98 cities in the Yangtze River Economic Belt from 2011 to 2018 were analyzed. The research shows that: ① The digital economy and economic development level of the Yangtze River Economic Belt both show an upward trend, and the growth rate of the digital economy level is greater than the economic development level. There are spatial differences between the two, and the overall level of digital economy and economic development in downstream cities is the same. Relatively high, the upper and middle reaches are the opposite. ② The coupling coordination degree of the Yangtze River Economic Belt has shown a steady upward trend, and the overall coupling coordination level has achieved a transition from mild imbalance to primary coordination; there are obvious spatial differences in the coupling coordination degree, showing an overall trend of downstream > midstream > upstream. ③The coupling coordination degree shows positive spatial autocorrelation, but with the passage of time, the spatial autocorrelation weakens; the overall change in the “high-high” agglomeration area of ??the coupling coordination degree is not large, and the “high-low” agglomeration area shows first After expanding and shrinking, the "low-low" agglomeration area maintains a downward trend.
