Topic Mining and Spatial Effect of China's Digital Economy Policy Texts
摘要
Abstract
The digital economy policy is one of the manifestations of the governments support for the de-velopment of the digital economy,and the analysis of policy characteristics is helpful to clarify the implemen-tation effect of the policy.Based on the characteristics of the digital economy and from the perspective of the digital economy industry chain,this study uses 468 comprehensive digital economy policies in China from 2017 to 2022,combined with text analysis methods,network analysis methods and spatial econometric mod-els.The results show that China's digital economy policies are divided into eight categories:talent training,enterprise and park development,service platform,technology development,industrial integration develop-ment,declaration and evaluation,management and planning,and rewards and subsidies.Overall,the digit-al economy policies have significantly promoted the development of the digital economy in both the region and neighboring regions.Policies related to talent training and technology development have shown signifi-cant positive externalities,and policies on enterprise and park development,service platforms,technology development,incentives and subsidies,and management and planning all show obvious digital economy pro-motion effects.The number of digital economy policies has a long-term impact on the development of the dig-ital economy,while the intensity of digital economy policies has a significant effect in the short term.关键词
