This study examines the collective use of the electronic information and communication channels and their impact on citizen participation for public discourse. Using both quantitative and qualitative research methods, we investigate public communication channels available for government service provision in a large metropolis in China. Specifically, four electronic communication channels are analyzed to assess the impacts of diverse dimensions for electronic participation from citizens to governmental discourse. Upon completion, the study will provide a useful framework with insights for both researchers and practitioners in the power of electronic information and communication channels in electronic participation in the public discourse.
