This study explores the influence of mass media on environmental protection in Hong Kong using longitudinal study and cross-sectional sample survey. The objective is to find ways to encourage the public's intentions to participate in various pro-environmental behaviours. The longitudinal study tests the agenda setting hypothesis that increased news reporting about the environment leads to increased public salience about environmental problems. The changes in the print news agenda and the public agenda in opinion polls from 1983 to 1995 were analyzed. A probability sample survey of 745 Hong Kong residents was conducted to test a model linking use of mass media and pro-environmental behavioural intentions. Results indicated that use of mass media for environmental news had great impact on the public's intentions to participate in various types of pro-environmental behaviours. Use of mass media for environmental news helped to increase knowledge about the environment and to establish favourable attitudes toward the environment. The direct effect of use of mass media on behavioural intentions was strong, indicating that use of mass media served as an important reminder to motivate green actions. Use of mass media for environmental news was also positively related to the degree of perceived social norms. The inclusion of the government and the mass media as sources of influence for environmental protection was first introduced and measured explicitly in the research program. Demographic variables had important and differential impact on use of mass media and environmental knowledge, attitudes, perceived social norms and behavioural intentions. The study has successfully developed reliable measures for key environmental concepts that are applicable to the Hong Kong society.
