胖东来模式注定无法扩张，小而美的商业店只能在小范围之内存在

Group 1 - The success of the company "胖东来" is attributed to a "small but beautiful" business model, which is effective in a limited area but faces challenges in expansion [1][2] - The company operates well in a local context, but replicating this success in larger cities like Beijing and Shanghai poses significant risks due to higher costs and management complexities [1][2] - The management and logistics costs increase substantially with expansion, undermining the advantages of the original business model [1] Group 2 - Employee wages in the retail industry are generally low, and a slight increase can have a significant impact; higher wages in big cities do not attract the same level of commitment as in economically backward regions [2] - Workers in economically disadvantaged areas are more motivated and willing to work hard for relatively lower wages, which contrasts with the work ethic observed in larger cities [2] - The emotional connection and regional pride of local customers contribute to their willingness to pay higher prices, which may not translate to other regions during expansion [3]
