摘要
文章首先运用熵值法和耦合协调度模型测度2015—2020年中国30个省份数字经济与实体经济的耦合协调度;然后,采用泰尔指数和核密度函数分析数字经济与实体经济耦合协调度的地区差异及动态演化特征;最后,运用空间杜宾模型分析影响数字经济与实体经济耦合协调度的因素,并对其进行空间效应分解和异质性分析。研究发现:中国数字经济与实体经济的耦合协调度逐年提高,但存在明显的空间分布不均现象和地区差异,各地区耦合协调度的相对差异逐年缩小但绝对差异不断扩大,同时极化现象逐年缓解;出口依存度、产业结构水平等均对数字经济与实体经济的耦合协调度有显著的正向影响,政府行为对数字经济与实体经济的耦合协调度存在负向的空间溢出效应,数字化人力资本水平和经济发展水平存在正向的空间溢出效应。
This paper first uses entropy method and coupling coordination degree model to measure the coupling coordination degree of digital economy and real economy in 30 provinces of China from 2015 to 2020,then uses Theil index and kernel density function to analyze the regional differences and dynamic evolution characteristics of the coupling coordination degree between dig-ital economy and real economy,and finally uses the spatial Durbin model to analyze the factors that affect the coupling coordina-tion degree of digital economy and real economy,and also analyzes the spatial effect decomposition and heterogeneity.The results go as below:The coupling coordination degree of China’s digital economy and the real economy is increasing year by year,but there are obvious uneven spatial distribution and regional differences.The relative difference of the coupling coordination degree in various regions is narrowing year by year but the absolute difference is expanding,and the polarization phenomenon is easing year by year.The degree of export dependence and the level of industrial structure have a significant positive impact on the cou-pling coordination degree of digital economy and real economy.The government behavior has a negative spatial spillover effect on the coupling coordination degree of digital economy and real economy,and the level of digital human capital and economic devel-opment has a positive spatial spillover effect.
