苏超爆火的关键，可能是成本低

Core Viewpoint - The success of grassroots sports events like Suzhou Super League (苏超) is primarily attributed to low costs rather than cultural or geographical factors [2][35]. Cost Analysis - Many grassroots sports events in China, including Suzhou Super League, share a common characteristic of low operational costs [3][19]. - In contrast to European leagues, where travel costs are minimal, the vast geographical size of China leads to significantly higher transportation costs for amateur players [11][13]. - The cost of participating in local leagues in China can escalate quickly, making it unaffordable for many amateur players [16][18]. Participation Factors - The community and collective identity play a crucial role in driving participation in local sports events, as individuals are more likely to support teams representing their locality or community [25][32]. - The emotional connection to local teams fosters a sense of belonging, encouraging attendance and participation in events [26][40]. Comparison with Other Activities - The participation levels in various activities like esports, fishing, and piano lessons vary significantly based on their associated costs, illustrating how increased costs can deter participation [17]. - The comparison highlights that lower costs lead to higher engagement, as seen in esports, while higher costs in activities like piano lessons limit participation [17]. Future Considerations - To expand grassroots leagues like Suzhou Super League, controlling costs is essential to maintain accessibility for amateur players [41]. - Increasing costs through formalization and professionalization could lead to a decline in local participation and community support [38][39].
