The sports competition performance industry is the main engine of sports industry，which plays an extremely important leading role in the high-quality development of sports industry. Under the joint action of government policy guidance and market innovation，the competition performance industry in the Yangtze River Delta has achieved rapid development in recent two years. At present，the Yangtze River Delta competition shows the trend of steady growth in industrial scale，continuous improvement in scale of sports events，vigorous development of brand sports events，increasingly significant overall benefits of events，continuous improvement of occupation events，increasing standards of running competitions，and continuous improvement of market environment. However，the COVID-19 pandemic also causes huge losses to the Yangtze River Delta sports competition performance industry. Main development experience：Explore a new mechanism for co-hosting competitions；create a new pattern of industrial development；explore the digital transformation of sports events and cultivate a new model of sports events；explore the multi subject competition mode and improve the professional level of competition operation；release the multiple functions of sports events；promote the integrated development of “sports+”“+sports”；explore the refined competition mode；comprehensively improve the level of safe competition. However，there are still some problems in the competition performance industry in the Yangtze River Delta，such as the quality of events needs to be further improved，the efficiency of events needs to be further enhanced，and the reform of “release，management and service” of sports events needs to be deepened. In the future，to promote the development of competition performance industry in the Yangtze River Delta，we need to improve the competition management service system，create a high-level sports event brand，promote the digital transformation of sports events，and promote the integrated development of sports events in the Yangtze River Delta.
