数字经济与高质量发展的耦合协调测度与评价研究

Coupling Coordination Measurement and Evaluation of Digital Economy and High-quality Development

基于2013—2018年中国271个地级及以上城市的数据,运用耦合协调度模型、Dagum基尼系数、Moran指数考察数字经济与高质量发展间的耦合关系。研究发现:数字经济与高质量发展的耦合协调度逐年递增,属于中度耦合协调类型;华南、华北和华东地区的耦合协调度较高,华中和西南地区的耦合协调度较低;城市数字经济与高质量发展的耦合协调度随城市等级的降低而下降;长江流域数字经济与高质量发展耦合协调度高于黄河流域,均属于中度耦合协调类型。中国数字经济与高质量发展耦合协调度总体差异逐年减小,超变密度是耦合协调度地区差异的主要来源,七大区域和不同等级城市耦合协调度的基尼系数与全国走势基本相同。城市间的耦合协调关系存在显著的空间效应,且空间效应存在明显区域异质性。

Based on the data of 271 cities in China from 2013 to 2018,the coupling coordination degree model, Dagum Gini coefficient and Moran index were used to investigate the coupling relationship between digital economy and high-quality development.The results show that the degree of coupling coordination between digital economy and high-quality development is increasing year by year, and it belongs to moderate coupling coordination type.The coupling coordination degree is higher in South China, North China and East China, but lower in Central China and Southwest China.The degree of coupling coordination between urban digital economy and high-quality development decreases with the decrease of city level.The coupling coordination degree of digital economy and high-quality development in the Yangtze River Basin is higher than that in the Yellow River Basin, which belongs to the moderate coupling coordination type.The overall difference of coupling coordination degree between China’s digital economy and high-quality development is decreasing year by year, and hypervariable density is the main source of regional differences in coupling coordination degree.The Gini coefficient of coupling coordination degree of seven regions and cities of different levels are basically the same as that of the whole country.The coupling coordination between cities has significant spatial effect, and the spatial effect has obvious regional heterogeneity.
