Research on the Level and Influencing Factors of Sports Market Integration in China——Empirical Study Based on Jing-jin-ji,Yangtze River Delta and Guangdong-Hong Kong-Macao

The study uses the relative price method to measure the development level and evolution of sports market integration in the three areas of Jing-Jin-Ji, Yangtze River Delta and Guangdong-Hong Kong-Macao from 2003 to 2018, and uses the "3D" theoretical analysis framework to find out the influencing factors. The results show that: During the investigation period, the evolution process of sports market integration in the three core regions is similar. The integration level is gradually improved, but there are differences. The level of market integration of sports in Guangdong-Hong Kong-Macao is the highest, while that in JingJin-Ji is the lowest. The integration of sports market has experienced three stages: the start-up stage, the preliminary cooperation stage and the in-depth cooperation stage. The three core regions have different levels of market integration of sports in different stages. The “3D” factor has a significant impact on the market integration of sports in three core regions, but it has heterogeneity.Jing-Jin-Ji are mainly affected by distance, density and integration factors. The Yangtze River Delta is mainly affected by distance and density factors, Guangdong-Hong Kong-Macao are mainly affected by density and integration factors. Jing-Jin-Ji should focus on perfecting the construction of infrastructure and regional sports industry layout, Yangtze river delta should further strengthen policy coordination, Guangdong-Hong Kong-Macao should promote liberalization and facilitation of the investment and trade. At the same time, the high quality development of the sports market integration in the three core regions needs both localization and globalization.
