The expansion of the scale of the elderly care industry, the acquisition of market share, and the seizure of high profits depend on the consistency between the ecological niche of the elderly care industry and the actual resource and environmental conditions. Based on the situation theory of ecological niche, this paper expands the factor of “energy” and represents the three dimensions of “state,” “potential,” and “energy” from three aspects: market niche, technology niche, and resource niche. Taking 220 listed companies as samples, this paper improves the traditional catastrophe progression evaluation model and uses structural equation modeling to test the validity of the indicator system, thereby conducting evaluation research on the ecological niche of the elderly care industry. From the results of niche potential energy measurement, the three dimensions of market niche, resource niche, and technology niche are unevenly developed, reflecting the lack of competitiveness of the elderly care industry.
