摘　　要：为了科学准确衡量我国省级地区数字经济规模和空间差异演变趋势,本文提出一种兼顾核算科学性和统计兼容性的方法,测算了2007—2020年我国30个省(区、市)的数字经济核心产业及其四类细分产业的增加值规模,进而分析了数字经济核心产业的空间发展格局和不平衡性的演变趋势,并通过SAR模型实证检验了我国数字经济核心产业发展的影响因素和空间溢出效应。研究显示:(1)30个省(区、市)的数字经济核心产业的总体规模差异显著。(2)四大类核心产业的空间发展格局呈现由东到西递减趋势;数字要素驱动业进一步向东部优势地区集聚,其他产业呈现从东部地区和东北地区向中西部地区转移的趋势。(3)各地区间的差异是造成我国数字经济差异的主要原因。(4)经济增长水平、政府科技支持力度、对外开放水平和技术创新水平与数字经济核心产业发展高度相关,这些因素的影响都存在空间溢出效应。In order to scientifically and accurately measure the evolution trend of the scale and spatial differences of the digital economy between provinces in China,this paper puts forward a method that takes into account both scientific accounting and statistical compatibility,and calculates the added value scale of the core industries of the digital economy and its four sub-industries in 30 provinces(autonomous regions and municipalities)in China from 2007 to 2020.Furthermore,the paper analyzes the spatial development pattern and the evolution trend of unbalance of the core industries of digital economy,and empirically tests the influencing factors and spatial spillover effect of the development of the core industries of China’s digital economy through SAR model.The results show that:(1)There is a significant difference in the overall scale of the core industries of the digital economy in 30 provinces and regions.(2)The spatial development pattern of the four core industries shows a decreasing trend from east to west;the digital factor-driven industry has further concentrated in the eastern region with advantages,and other industries have shown a trend of transferring from the eastern and northeastern regions to the central and western regions.(3)The differences between various regions are the main reasons for the differences in China's digital economy.(4)The level of economic growth,the level of government scientific and technological support,the level of opening up and the level of technological innovation are highly correlated with the development of the core industries of the digital economy,and the influence of these factors has a spatial spillover effect.
