The swift ascension of the sports industry can be attributed to the advancements of the contemporary era, and serves as a significant indication of the industry’s progression towards a novel phase and pinnacle. Despite a delayed inception, China’s sports industry has experienced a swift evolution and has established a unique developmental framework, thereby establishing a firm groundwork for the prospective growth of China’s sports industry. The sports industry of China is currently encountering fresh prospects for growth in the contemporary era. However, it is also confronted with formidable obstacles and strains that necessitate careful handling. To attain novel breakthroughs and advancements, it remains imperative to explore innovative perspectives and avenues. The assessment of the sports industry’s high-quality development in the new era is a classic Multiple Attribute Group Decision Making (MAGDM) problem. The TODIM and VIKOR methodologies have been employed in addressing Multiple Attribute Group Decision Making (MAGDM) challenges in current times. Fuzzy number intuitionistic fuzzy sets (FNIFS) serve as a valuable instrument in the characterization of uncertain information for the comprehensive assessment of the high-quality development of the sports industry in the contemporary era. The present manuscript introduces the construction of the fuzzy number intuitionistic fuzzy TODIM-VIKOR (FNIF-TODIM-VIKOR) method, which is designed to address multiple attribute group decision making (MAGDM) problems in the context of fuzzy number intuitionistic fuzzy sets (FNIFSs). Ultimately, a numerical case study is presented to comprehensively evaluate the high-quality development of the sports industry in the new era, in order to validate the proposed methodology.
