中国数字经济发展的时空演变趋势与政策文本分析

Spatio-temporal Evolutionary Trends and Policy Text Analysis of China’s Digital Economy Development

数字经济是全球经济发展的重大趋势,也是我国经济转型升级的重要战略。在数字化浪潮下,数字经济已成为促进我国经济高质量发展的新动力,数字经济发展水平的测度就成为亟须解决的问题。基于我国31省市区2011-2021年的面板数据,运用熵值法综合评价我国数字经济发展水平,用核密度估计深入分析数字经济发展的时空演变趋势。研究发现,中国数字经济发展水平呈现出东强西弱、中部居中的特征,东部和西部区域内各省份的数字经济发展水平差距逐渐明显。根据各地区政府工作报告中提及数字经济的词频统计结果,提出推动数字经济发展水平的对策。
