**1. Introduction**

As a significant component of cultural heritage, industrial heritage preserves the memories of regional and urban development as well as the historical fashions and traits of various nations and regions. Today, the adaptive reuse of industrial heritage has largely replaced demolition and reconstruction. How to maximize the value of industrial heritage while supporting regional and urban transformation and better integrating urban regeneration is a significant topic in the field of heritage conservation. Research on the adaptive reuse of industrial heritage has focused on the study of specific strategies for reuse [1] and heritage value assessment [2]. However, many cases have demonstrated that industrial heritage transformation and utilization strategies frequently rely on value assessment rather than adaptive reuse potential assessment, which does not lead to effective industrial heritage protection, full utilization, or the effective promotion of sustainable urban regeneration. Since more than ten years ago, Beijing has been preserving and reusing its industrial heritage. Numerous studies on actual instances of industrial heritage transformation have been conducted, and specific outcomes have been obtained in the fields of industrial heritage preservation and reuse, as well as value assessment. A thorough potentiality evaluation system that is pertinent, systematic, and useful is lacking in the field of research on the evaluation of reuse opportunities. The prerequisites of and keys to

the adaptive reuse of industrial heritage now include how to construct a comprehensive evaluation index system to express the reuse potentiality of industrial heritage and how to thoroughly consider the current situation of industrial heritage.

Figure 1 depicts the research framework of this paper. Research on the potentiality of reusing industrial heritage clarifies the concept definition of reuse potentiality assessment, the selection of an evaluation index system, and quantitative methodologies. The rationale for selecting the indicators for the assessment of adaptive reuse potentiality is provided, and the industrial heritage value assessment system is constructed at various levels of autologous value, retrofitting value, and potential benefit value from the building dimension and urban dimension, respectively. In the literature review and material analysis, quantitative research methodologies for assessing the adaptive reuse potentiality of industrial heritage are included. To improve the scientific and unbiased results of the potentiality evaluation, the comprehensive weights of the evaluation indicators were calculated, and the technique for ordering preferences by similarity to the ideal solution (TOPSIS) was used to determine the relative size of the reuse potentialities of various industrial parks as well as the specific potentiality distribution values of each park, which were included in the method description. Ultimately, the applicability of the evaluation method is demonstrated by assessing the potentialities of eight industrial parks in Beijing, which are included in the evaluation results. The evaluation results provide robust, adaptive guidance for both decision making and the management of industrial heritage restoration. Predicting the timing, purpose, and focus of exploitation, as well as proposing reuse plans for the development of the area, are helpful for industrial heritage parks that have not yet been renovated; for those that have been renovated and are currently in use, the potential values and distribution are clarified, as are suggestions for optimizing the current renovation and operational management. This discussion and conclusion comprise this part.
