A Consideration of Media Environment Regarding Air Pollution Problems in China: Based on the Content Analysis of the Reports of "People's Daily" from Jan. 1,1970 to Nov. 30,2011

The problem of PM2.5 in China has become a worldwide issue, and there are many daily reports covering it in many different forms. Actually, in China, air pollution coverage began in the 1970s, while news and features reported about greenhouse gases to particulate matter like PM2.5. By analyzing past coverage, the tendency of media attention and concern about air pollution issues regarding the mainstream consciousness, and the changes in reporting methods can be seen, and impacts on public opinion can also be inferred. In this study, a quantitative content analysis of the articles in the People's Daily newspaper from 1970.1.1 to 2011.11.30 was conducted. Based on the results, through 40 years of coverage, the public awareness of air pollution has taken shape. However, whether a deeper understanding and initiatives to participate have been formed are still problems.
