This study uses data from the 2005 wave of World Values Survey (WVS 2005), to explore and compare the relations between media use and postmaterialist value orientations in China and the US. The data analysis showed that the younger generations in China have stronger postmaterialist value orientations than the older generations. American society has stronger postmaterialist value orientations than Chinese society as a whole, but fewer obvious generational differences. The study also found that media use has a greater effect on values in China than in the US.
