Based on the microscopic survey data of 100 vegetable cooperatives in Sichuan Province, this paper empirically analyzes the influence of brand certification on cooperatives participating in the ecommerce by binary logistic regression model. The results show that the proportion of Sichuan vegetable cooperatives participating in the e-commerce is generally lower, which needs further improvement. Brand certification has a positive role in promoting cooperatives to participate in the e-commerce, with a marginal contribution of 19.7%. In addition, government sales support has a positive impact on the cooperative ecommerce, which is an important guarantee for promoting cooperatives to participate in the e-commerce. While the difficulty of agricultural product sales has a negative impact on the cooperative e-commerce, and the more difficult the agricultural products are sold, the higher the probability that the cooperative will participate in the e-commerce. Thus, this article puts forward policy suggestions such as actively promoting cooperatives to participate in brand certification, promoting cooperatives to participate in the e-commerce according to local conditions and strengthening government sales support.
