我国产业数字化水平的地区差异与分布动态演进

Regional Disparities and Distribution Dynamic Evolution of China’s Industrial Digitization Level

文章在构建产业数字化评价指标体系的基础上,运用熵权法和线性加权法相结合的方法准确测度我国整体及四大经济区产业数字化水平,运用Kernel密度估计、Dagum基尼系数探究我国省级层面产业数字化的分布动态演进和地区差异。结果显示:整体上,全国及各地区产业数字化水平呈逐年上升趋势,但是各地区之间存在较大差距,且存在一定的发散趋势;全国产业数字化水平总体差异呈不断增大趋势,差异来源贡献度表现为“区域间差异最大,区域内差异次之,超变密度最小”;中西部地区存在明显的极化现象。

By constructing an evaluation index system of industrial digitalization,this paper uses the combination of entropy weight method and linear weighting method to accurately measure the overall level of industrial digitalization in China and four regions,and then uses Kernel density estimation and Dagum Gini coefficient to explore the dynamic evolution of distribution and regional disparities of industrial digitalization at the provincial level in China.The conclusions are as below:On the whole,the level of national and regional industrial digitization shows an increasing trend year by year,but there is a large gap between regions and there is a certain divergence trend.The overall difference in the level of industrial digitalization across the country shows an increasing trend,and the contribution of the sources of difference is as following:“inter-regional difference is the largest,intra-regional difference the second,and super-variable density is the smallest”.There are obvious polarization phenomena in the central and western regions.
