Abstract: In view of the researches on emergy theory and the complexity of industrial systems，this study reviewed the theoretical research progress and the application of emergy theory on industrial systems. The research progress of hotspots on emergy theory in aspects of establishment and improvement of the emergy indicators system，explanation of emergy algebra and the evaluation of industrial systems combined with other theories were summarized. This study also pointed out the future research directions of emergy theory in building of the unified emergy indicators and evaluating the interior of industrial systems.

摘要： 能值理论由于考虑了环境投入以及将不同物质和能量置于同一个平台上进行评价的特性而得到了广泛的应用。鉴于能值理论研究的深入以及工业系统自身的复杂性，本文系统回顾了能值理论在工业系统中的应用与相关理论研究进展，总结了其在能值指标体系的建立与改进、能值代数的阐释以及联合其它理论方法对工业系统进行评价等热点问题的研究情况，同时指出构建统一的能值评价体系以及对系统内部进行更深入的研究将会成为新的能值理论研究方向。
