Reexamining the relations between socio-demographic characteristics and individual environmental concern: Evidence from Shanghai data

This study reexamines the influence of socio-demographic characteristics on individual environmental concern by applying a pooled sample of 1200 individuals in Shanghai, China. Previous studies, which made efforts to explain environmental concern as a function of social structure, suggest that there are traditionally five observations (the age, gender, social class, residence, and political orientation effects) for the relations between socio-demographic characteristics and individual environmental concerns. In this study, we first conduct a factor analysis to a group of 11 environmental concern measures and then use the resulting factors to test three observations (the age, gender, and social class effects) by applying a seemingly unrelated regressions (SUR) model. As a result, high household income and high education level have reacted positively to environmental concern as expected. However, we find that in contrast to most of the previous studies, age has shown positive reaction to individual environmental concern, implying that the older generation is more concerned about the environment than the younger population. In addition, the SUR results indicate that women in Shanghai seem less concerned about the environment than men. Other socio-demographic characteristics such as employment status and household size are found to be almost irrelevant to environmental concern. (C) 2007 Elsevier Ltd. All rights reserved.
