Research on the Policy of Transportation Data Management Based on PMC Index

Data management related policies play a guiding role in the digital transformation of the whole society. Under the guidance of policies, data sharing and data security have been paid attention to and standardized to a certain extent. The sorting and evaluation of existing policies helps to provide a quantitative basis for policy improvement and optimization in the future. Based on the data management related policy texts published by governments at all levels in China, this study selects relevant data management policies in the field of transportation, conducts quantitative analysis on the policy texts based on text analysis tools and PMC policy evaluation model, obtains the PMC index of each policy, and draws the PMC surface chart. Each policy is evaluated according to the PMC index, and its shortcomings are found out by studying the multiple input-output table and the PMC index table, and the methods to overcome these shortcomings through optimization are proposed.
