本研究以內容分析法，檢視《南方周末》跨地區新聞輿論監督，研究發現：《南方周末》對跨地區新聞輿論監督報導，相當重視；監督區域，以北京、四川居多；監督領域，偏重政法與醫療衛生，議題以司法與國家執政居多；媒體多以「代表公眾」角色從事監督；在監督的層級與直接程度，都有不錯的表現。但比較2005年5月前、後，跨地區輿論監督報導，顯著減少，足見國家機器影響力仍強，並與媒體市場驅力、以及媒體專業主義追求，在中國媒體的新聞決策中，相互拉扯。 This study employs content analysis to examine the cross-regional news supervision by public opinion of “Southern Weekly” in mainland China. The results indicated that the cross-regional news supervision by public opinion is emphasized, and supervision regions are mostly in Beijing and Sichuan. In addition, issues being supervised are mostly topics of justice and politics in nature, and often focused on the political, legal, medical, and health agenda. Furthermore, the Southern Weekly most of the times plays the “on behalf of the public” role to engage in supervision. Finally, both the breadth and depth of the cross-regional news supervision by public opinion have good performance. However the numbers of cross-regional news supervision by public opinion have been reduced significantly since May 2005, which is obvious the wrestle among the government power, the market driving force and pursuing journalistic professionalism on news supervision in Mainland China.
