In the face of the corona virus disease 2019 (COVID-19) pandemic, it is essential to stabilize the security of urban “shopping baskets”. Through a survey and interviews with 46 agricultural cooperatives in Shanghai, this paper analyzes the impact of the pandemic on vegetable production and offers suggestions on agricultural insurance. The research results show that: (1) the pandemic has impacted almost all stages of the vegetable supply chain but has had a greater impact on the sales stage; (2) the market risks of vegetable production have increased significantly, and the gap between the field price and the market price has widened. The sales price difference between traditional channels and e-commerce is notable; (3) farmers' incomes have generally declined due to the COVID-19 pandemic, and traditional small-scale farmers have suffered more losses; and (4) agricultural insurance plays an important role in stabilizing the supply of vegetables to the city. To minimize the impact of the pandemic on vegetable production and to stabilize both urban “shopping baskets” and farmers' incomes, it is necessary to further improve agricultural insurance, especially to provide insurance against market risks.

面对2019年日冕病毒病（COVID-19）大流行，稳定城市“购物篮”的安全至关重要。通过对上海46家农业合作社的调查和访谈，本文分析了大流行对蔬菜生产的影响，并为农业保险提供了建议。研究结果表明：（1）大流行影响了蔬菜供应链的几乎所有阶段，但对销售阶段的影响更大；（2）蔬菜生产的市场风险显着增加，田间价格与市场价格之间的差距拉大。传统渠道与电子商务之间的销售价格差异明显；（3）由于COVID-19大流行，农民的收入普遍下降，传统的小农户蒙受的损失更大；（4）农业保险在稳定城市蔬菜供应方面发挥着重要作用。为了最大程度地减少大流行对蔬菜生产的影响并稳定城市的“购物篮”和农民的收入，有必要进一步改善农业保险，特别是提供针对市场风险的保险。
