Civic scientific literacy (CSL) is an important factor for the development of any country, and this is especially true for a country which is under development and at the same time pursues sustainability. In this article, we conduct the firstly systematic study of CSL in China based on survey data in 2013. Under the multi-dimension CSL framework and by using item response theory, we assess the CSL level in China, which can be fairly compared with that in U.S. and Europe (US-EU). The comparable survey results provided a number of implicational findings: for example, the status of CSL of China in 2013 would have ranked as middling and poor compared to the CSL results for the various US-EU countries in 1995 and 2005, respectively. Some group-based analyses were also conducted to show how people's attitudes to the environment and socio-environmental behaviours correlate with the CSL-qualified rate in China. The empirical results provided by this study not only can serve as references for improving CSL in China or other emerging countries that also address the sustainability issues during development, but could also serve as indicators for future studies (e.g., in causational modelling).
