**6. Conclusions**

This paper takes as its research object the existing successfully reused industrial parks in Beijing, combines the current reuse statuses and potentiality characteristics of the urban dimension, breaks through the traditional emphasis on the value assessment of the heritage itself, introduces potential evaluation factors that promote urban renewal, and forms a multi-faceted and multi-level comprehensive reuse potentiality evaluation system. Through a comprehensive comparison of various evaluation methods and by taking into account the fuzzy nature of the indicators of the evaluation object of potential, linearly weighted comprehensive weights are used to determine the parameters of each indicator, and Improved Entropy TOPSIS is used to quantify the ranking and relative value of industrial park reuse potentiality. Finally, the scientific validity and feasibility of the research framework for revealing the reuse advantages and potential distribution of established industrial heritage sites are validated through the application of actual cases in industrial parks. The industrial heritage reuse potentiality evaluation study enhances the accuracy and effectiveness of proprietors and practitioners in formulating reuse strategies at the implementation level, thereby maximizing the sustainable use of scarce resources. The revitalization of industrial heritage through adaptive reuse continues historical lineage and contributes to urban development.

The assessment of the reuse potentiality of industrial heritage involves many evaluation index factors, and this paper only calculates the relative value of potentiality for the primary and secondary evaluation index systems because the scoring basis and index composition of the three-tier index system may change due to the different evaluations of industrial heritage parks. It is necessary to further quantify the potentiality of the evaluation content and score after a specific analysis of the evaluation objects. The focus of this paper is to propose the content of graded indicators and the calculation of the relative potential size for the evaluation of industrial heritage in utilization potentiality in the urban dimension with insufficient research on optimization and improvement after the evaluation. The next stage will be to scientifically analyze the potentiality distribution of each park based on the research findings, clarify the advantages and disadvantages of transformation, and then enhance the reuse potential evaluation index system.

The evaluation system contains more indicators to obtain more comprehensive evaluation data, and it is difficult to determine the evaluation parameters and obtain the corresponding data, so the scientific quantification of the indicator data and the simplification of the evaluation system are future directions for research improvement. To broaden the compatibility of the evaluation methods and adapt them to various phases of reuse, such as preliminary research, design, construction, and operation, it is necessary to strengthen and improve the potentiality evaluation system by supporting cross-disciplinary and actual research.
