This paper,based on the characteristics of the openness of China's service industry,constructs an index sys-tem for service industry openness from three aspects:the internal development level of the service industry,the level of ex-ternal openness of the service industry,and the development environment of the service industry.Using data from 30 provinc-es in China from 2012 to 2021,the level of service industry openness is measured and analyzed through factor analysis and arrives at the following conclusions.Firstly,from a temporal perspective,the trajectory of the service industry openness in Chinese provinces is clear:the period from 2012 to 2016 marks the initial development phase,2017 to 2018 signifies the ac-celerated development phase,and 2019 to 2021 represents the structural adjustment and deepening openness phase.Second-ly,from a regional perspective,the level of service industry openness in the developed provinces of the eastern region has shown high stability throughout the entire period,with Beijing,Shanghai,and Guangdong consistently leading the way.The openness level in the central and western regions accelerated during the period from 2017 to 2021 and it reflects the imple-mentation of the Western Development Strategy by the government and the strengthened policy support for these regions.
