Entering the chain era, market competition has expanded from individual enterprises to the industrial chain. The system of leading-chain enterprises has been implemented across China to select enterprises with strong innovation capability. Leading-chain enterprises play a vital role in promoting industrial innovation and development, integrating industrial chain resources, and driving the coordinated development of industrial chain enterprises, and they present strong ecological dominance which refers to the influence, control and leading power of an enterprise in its industrial ecology. The 14th Five-Year Plan has emphasized the necessity to build leading-chain enterprises with ecological dominance and core competitiveness, and give full play to their role models in the industrial and supply chains. In order to give full play to the leading role of leading-chain enterprises, it is essential to make an accurate evaluation of the ecological dominance of leading-chain enterprises first. However, at present, compared with the strategic requirements of the state on upgrading the modernization level of the industrial chain through the main working mechanism of the industrial chain, and the practical exploration of enterprises to promote the coordination of the industrial chain, the evaluation research on the ecological dominance of leading-chain enterprises is still relatively lagging behind. Therefore, this paper selects the main enterprises of the high-end equipment manufacturing industry chain and the aluminum magnesium deep-processing industry chain and their related enterprises in Shanxi province as the research objects, carries out exploratory research by the grounded theory method, and extracts the evaluation index system of the ecological dominance of the main enterprises through coding from three aspects: leading ability in technological innovation, ability in industrial cooperation and integration, and ability to lead industry development. Meanwhile, the corresponding measurement scale is developed to provide theoretical and practical guidance for the evaluation and cultivation of the ecological dominance of the leading-chain enterprises and to explore methods for provinces and cities to select and evaluate leading-chain enterprises.#br#　　The DEMATEL-ANP evaluation model is established based on the correlation and feedback relationship between evaluation indicators to determine the reference range of quantitative weights of the index system. DEMATEL is used to determine the correlation between indicators, and ANP is used to measure the weight of indicators. The measurement results show that from the perspective of industrial chain collaboration, the weight of leading ability in technological innovation is the largest and the importance is higher, followed by ability to lead industry development, and the weight of ability in industrial cooperation and integration is the least. In order to verify the scientificity and feasibility of the ecological dominance evaluation index system, this paper also selects member enterprises in the key industrial chain of Shanxi province to evaluate ecological dominance. The evaluation results are generally in line with the subjective evaluation of the main enterprises in the industrial chain,indicating that the primacy of the main enterprises is not obvious.#br#　　This paper draws the conclusions that , firstly, a weight system for quantitative identification and evaluation of leading-chain-enterprises is established based on the leading ability in technological innovation, ability in industrial cooperation and integration, and ability to lead industry development; secondly quantitative evaluation of the ecological dominance of leading-chain-enterprises is helpful to identify the potential of the enterprises, carry out early cultivation and evaluate the effect of the dominance; thirdly, the efforts to promote the cooperation mechanism between leading-chain-enterprises and core enterprises and the development of chain cluster ecology should be emphasized in the evaluation orientation of ecological dominance of leading-chain-enterprises. Then, this paper puts forward targeted policy suggestions to improve the cultivation and service mechanisms of leading-chain enterprises. First, it is critical to establish a selection and identification standard system that combines qualitative and quantitative evaluation based on the industry characteristics and ecological dominant status of chain owners. Second, there is an urgent need to strengthen the top-level design of supporting the construction of industrial innovation consortia, build a policy system that is conducive to the deep integration of innovation chains and industrial chains, and guide innovation resources to meet strategic innovation needs.#br#
