| Based on the core of the Harmonious Symbiosis Theory, this study establishes the adaptability of the symbiosis theory for nuclear power enterprises from the perspectives of diversity, coordination, and dynamics. Guided by the Dual Carbon Goals, it embeds low-carbon value; based on the concept of High-Quality Development, it extends innovative value. The organic integration of these three provides theoretical support for the construction of financial ecological indicators for nuclear power enterprises. t comprehensively sorts out the financial attributes of upstream, midstream, and downstream enterprises, which are the symbiotic units in the nuclear power industry chain. From the perspective of symbiosis models, it analyzes the cost-sharing mechanism between upstream and midstream enterprises, and the risk joint prevention mechanism between midstream and downstream enterprises. From the perspective of the symbiotic environment, it analyzes the driving roles of policies, technologies, and markets on nuclear power enterprises, namely mandatory guidance, technical empowerment, and competitive impetus. On the basis of systematically analyzing the financial attributes of upstream, midstream, and downstream enterprises in the nuclear power industry chain, this study points out that the essence of financial attributes lies in capital and profits. Taking this as a foundation, and in accordance with the theory of constructing financial ecological indicators for nuclear power enterprises, it classifies and builds a "four-in-one" financial ecological indicator system from the environmental, ecological, operational, and financial dimensions, providing theoretical guidance for the comprehensive and scientific evaluation of nuclear power enterprises. |
