基于文本量化分析的区块链政策比较研究

摘要：本文基于LDA主题建模和Logistic回归等文本量化分析方法，从政策主题、政策工具及创新价值链等三个维度对我国中央及地方政府的区块链政策进行全面的比较分析。研究发现：中央政府主要运用法规管制和技术基础设施两种政策工具，重点关注基础理论研究和技术研发环节，而地方政府主要运用试点示范与资金投入等政策工具，重点关注区块链产业应用环节。为更好地促进区块链技术协调发展，应当优化政策工具结构配比，强化人才建设和技术支持；完善环境型政策工具内部结构，提高需求型政策工具的应用比重，构建与创新价值链相应环节高度匹配的政策工具组合。

The Comparative Study of Blockchain Policies Based on Text Quantitative Analysis

Abstract: Based on LDA topic modeling and logistic regression and other text quantitative analysis methods, this paper conducts a comprehensive comparative analysis of the blockchain policies of the central and local governments in China from three dimensions, including policy themes, policy tools, and innovative value chains. This study finds that the central government mainly uses two policy tools, namely regulatory control and technology infrastructure, to focus on basic theoretical research and technology research and development, while local governments mainly use policy tools such as pilot demonstrations and capital investment to focus on the application of blockchain industry. In order to better promote the coordinated development of blockchain technology, it is necessary to optimize the structure of policy tools, strengthen talent construction and technical support; improve the internal structure of environmental policy tools, increase the application proportion of demand-based policy tools, and build a policy tool portfolio that highly matches the corresponding links of the innovation value chain.
