三维框架下我国数据要素政策量化研究

Quantification Research on China’s Data Elements Policy under a 3D Framework

[目的/意义]分析我国数据要素政策在政策工具、政策主题以及政策效力上的合理性和科学性,对于推动数据要素的可持续发展具有现实意义。[方法/过程]从完善数据要素政策的需求出发,以39篇政策文本为样本,通过内容分析法、TF-IDF算法、LDA主题建模和PMC指数模型对其进行分析,并且根据结果提出可行性建议。[结果/结论]我国在数据要素政策工具及其内部子工具的使用上存在不均衡性,总体呈现出重供给、轻需求的特征;政策主题覆盖全面,但存在区域发展不平衡问题;政策效力整体表现良好,但在政策时效、政策性质等指标上的得分仍有提升空间。

[Purpose/significance]It is of practical significance to analyze the rationality and scientificity of China’s data elements policies in terms of policy tools,policy themes,and policy effectiveness to promote the sustainable development of data elements.[Method/process]The paper takes 39 policy texts as samples,analyzes them through content analysis method,TF-IDF algorithm,LDA theme modeling and PMC index model,and puts forward feasible suggestions based on the results.[Result/conclusion]The results show that:①There is an imbalance in the use of data elements policy tools and their internal sub-tools,which is generally characterized by the Chinese government’s preference for supply-side policy tools and less use of demand-side policy tools.②There is a comprehensive coverage of policy themes,but there is an imbalance in regional development.③The overall performance of policy effectiveness is good,but there is still room for improvement of the scores on the indexes,such as policy timeliness and policy nature.
