From the general bazaar market to supermarkets, restaurants, airports, etc., Shuangliuyu rose from 8 yuan/kg to 60 yuan/kg, with an annual output value of 350 million yuan. The level of agricultural production has increased significantly. The protection of geographical indication products is organically combined with agricultural standardization and brand building, which has improved the grade of agricultural products. The ability of farmers to increase their income has been continuously enhanced. The development of dual-stream GI products has promoted the rapid development of rural tourism. The county has built a large number of sightseeing areas such as “Golden Dragonfly” and “Strawberry Red Pearl Harbor”. The production efficiency has been greatly improved and the income of farmers has been increasing. In 2005, the per capita net income of farmers in the county reached 6,050 yuan. In 2010, the per capita net income of farmers in the county reached 8,760 yuan, and the per capita net income of farmers in the planting area reached 9,570 yuan. The infrastructure of the core area of ​​geographical indications has been significantly improved, which has led to the improvement of rural landscapes and the construction of new countryside, and promoted the integration of urban and rural areas. The rural roads have reached more than 1,900 kilometers. The product awards were rated as “the first batch of high-quality production bases in Sichuan Province”, Taiping Town was listed as “the first batch of agricultural standardization demonstration towns in Sichuan Province”, and the base was identified as “non-polluted agricultural production base”, 2004 Brands such as “Xinkang”, “Sancha” and “Green Hi” were certified as “green food” and “nuisance-free agricultural products” respectively. The project “Study on Ecological Adaptability and Cultivation Techniques” jointly completed by Sichuan Academy of Agricultural Sciences and Shuangliu County won the third prize of Sichuan Provincial People's Government in 2004, and the “High-quality and High-yield Cultivation Techniques Promotion Project” completed by Shuangliu County in 2005. He won the first prize of the 4th “Golden Bridge Project” (2002-2004) outstanding project of Chengdu Municipal People's Government and the Sichuan Science and Technology Association Excellence Award.
