<p>Boundary studies in STS are concerned with the co-production and inter-construction of power between science and politics, exploring who defines, how to define, and why issues are defined and set in certain manners. This study analyzes boundary work on energy issues as a debate and negotiation between multiple interests under the STS perspective. Using social network analysis (content and discourse analysis), this study takes the New York Times’ coverage of China’s clean energy since 2007 as an example to explore the distinction and alliance between scientific knowledge and political decision-making, as well as the typical significance of the knowledge-politics debate. The study findings reveal that the boundary construction of energy issues is manifested in the shape of “interpretive communities” reached through the co-production of media, business enterprises, governments, and the public. By adjusting the visibility of problems in tandem with policy changes, citing government and enterprise sources in preference to others, and employing the discourse strategy of relevant issues, the media has shaped a discourse advantage based on the specific knowledge linkages whereas the public selectively extrapolates or reproduces the issue boundaries defined by the media, and categorizes into distinct debate frameworks aligned with their own interest orientation and empirical knowledge, reinforcing the development of salience, credibility, and legitimacy of the boundary work of the energy issue.</p>
