摘　　要：本文使用滴权法与耦合协调度模型,测算出中国31个省市在2000-2019年问的实体经济与虚拟经济协调发展水平,首次考虑结合Moran'sⅠ指数、Dagum基尼系数及其分解、Kernel核密度估计方法分析中国实体经济与虚拟经济协调发展水平的区域异质性特征。结果表明:(1)我国各个省市的实体经济与虚拟经济协调发展水平都在逐年提升,较多省市依然处于不同程度的非协调发展状态,目前四大区域实体经济与虚拟经济协调发展的平均水平由高到低依次为东部、中部、东北、西部。(2)我国实体经济与虚拟经济协调发展水平具有明显的空间正相关性和空间集聚特征,表现为显著高-高集聚特征的省市都位于东部地区,而表现为显著低-低集聚特征的省市都位于西部地区.(3)我国实体经济与虚拟经济协调发展水平的总体相对差异有60%以上是区域问相对差异造成的,西部地区的区域内相对差异最大,东部地区与西部地区之间的相对差异最大。(4)全国及四大区域实体经济与虚拟经济协调发展水平的绝对差异都在扩大,较为落后的省市难以在短期内赶超领先的省市。根据研究结论,提出可以促进我国实体经济与虚拟经济协调发展、缩小区域差距的对策建议。This paper measures the coordinated development level between the real economy and the virtual economy in China's 31 provinces and cities during 2000 to 2019,by entropy weight method and coupling coordination degree model For the first time,it is considered to combine Moran's Iindex,Dagum Gini coefficient and its decomposition,Kernel density estimation method to analyze its regional heterogeneity Results show that:(1)Allof China's provinces and cities have an increasing coordinated development level between the real economy and the virtual economy year by year,many provinces and cities are still in different degrees of non-coordinated development state.At present,the average level of four regions in descending order is east,central,northeast and west.(2)The level of coordinated development between the real economy and the virtual economy in China has obvious spatial positive correlation and spatial agglomeration characteristics Provinces and cities with significant high-high agglomeration characteristics are all located in the eastern region while provinces and cities with significant low-low agglomeration characteristics are all located in the western region.(3)More than sixty percent of the overall relative difference in the level of coordinated development between the real economy and the virtual economy in China is caused by the relative difference between regions,the western region has the largest intraregional relative difference,while relative difference between the eastern region and the western region is largest.(4)The absolute difference in the level of coordinated development between the real economy and the virtual economy in Chinaand its four regions is expanding,it is difficult for the backward provinces and cities to catch up with the leading provinces and cities in the short term.According to the conclusions of this research,some suggestions that can promote the coordinated development between China's real economy and virtual economy and reduce the regional differences are put forward.
