Abstract: The regional price level is one of the important variables affecting the real input of public services and the real income of households in a region, and also an important factor of actual living standards, closely related to the sense of gain and happiness. In order to reflect the spatial differences and changes in household consumption price levels of China from 2015 to 2019, the PPP method is employed in this paper to calculate the sub-national PPP of 31 provinces. The main findings are: Taking Beijing as the benchmark region, the provincial PPPs of China are between 0.8011?1.0150 in 2017; For goods and services, the spatial price differences of goods are quite small, while the differences of services are relatively large; By category, the spatial price differences of “Food, Tobacco and Alcohol”, “Articles for Daily Use and Services” and “Health Care” are relatively small, while the differences of “Clothing” and “Housing” are relatively large; From the dynamic perspective, the regional price level of Eastern China, Central China and Western China narrowed before 2017, but expanded after that, which was mainly led by the price fluctuation of services in “Housing” and “Health Care”.
