Research on Interprovincial Digital Economy Policies Based on PMC Index Model

The digital economy is an essential engine driving the high-quality development of China’s economy. The healthy development of the digital economy is inseparable from the scientific guidance and effective regulation of policies. This paper collected 794 digital economy policies at the national and provincial levels, used the BERTopic algorithm to extract digital economy policy topics, improved the PMC index model evaluation index system based on the policy topics, and evaluated and researched the digital economy policies of Guangdong, Jiangsu, Zhejiang and Shandong. This research found that the four provinces, under the guidance of the central government and based on the actual conditions of the provinces, have formulated policy lines with their own characteristics; at the same time, the policies also generally have issues such as unclear implementation paths and weak predictions of the long-term development of the digital economy. Finally, based on research findings, this paper summarizes the directions in which provincial digital economy policies can be optimized, in order to provide a reference for the supply of digital economy policies and improve policy effectiveness.
