Abstract: 【Purpose/significance】This paper analyzes the temporal effect of policy tools on the balanced development of public digital cultural services in China, and provides a reference for the high-quality construction and comprehensive and balanced development of China′s public digital cultural service policy system.【Method/process】Collect and sort out the data of various time series indicators and construct the corresponding evaluation index system, combined with the policy texts of China′s public digital cultural services from 2011 to 2022, and construct a vector autoregressive model with the word frequency of the policy instrument as the explanatory variable and the equilibrium index as the explanatory variable, and conduct empirical analysis.【Result/conclusion】The results show that the balanced development of public digital cultural services in China is affected by three types of policy instruments. Among them, the driving force of environment-based policy tools on the balanced development of public digital cultural services increases with time, demand-based policy tools can promote the balanced development of public digital cultural services in the short term, and supply-oriented policy tools can improve the balanced development of public digital cultural services in China in the long run, but have a negative impact in the medium term of development.【Innovation/limitation】This paper discusses the influence mechanism of different types of policy tools on the balanced development of public digital cultural services, and intends to improve the accuracy of index selection through text mining methods in the future.
