The baking industry in China faces several challenges that hinder its growth and success. Firstly, there is a lack of established brands with strong influence and recognition, as most enterprises are still in their early stages and lack brand advantage. Secondly, the shortage of skilled and experienced bakers is a significant issue, as most bakers lack professional education and training. Thirdly, the unstable supply of baking materials, including flour, sugar, eggs, and cream, affects business operations due to price fluctuations. Moreover, the industry faces intense competition, requiring constant innovation and improvement to maintain a competitive edge. Additionally, the heavy tax burden, including value-added tax, business tax, and income tax, adds pressure to business operations. Lastly, the industry must comply with high environmental standards, including wastewater and exhaust gas treatment, which also impacts business operations.
