Abstract: The improved entropy method was used to calculate and evaluate the development level of modern urban agriculture of 26 cities in Yangtze River Delta urban agglomeration from five dimensions： The guarantee ability of the products of vegetable-basket project, the level of agricultural ecology and sustainable development, the level of integration of three industries, the gathering level of advanced agricultural production factors, and the level of modern agricultural management. The results show that the level of urban modern agriculture development in the Yangtze River Delta urban agglomeration is relatively high, but there is an imbalance in the level of urban modern agricultural development within the urban agglomeration. There is a big gap between Anhui province and the other three provinces of Jiangsu, Zhejiang and Shanghai in the overall level of urban modern agricultural development, but Anhui province has its own advantages in five dimensions. In view of the conclusion, it put forward some countermeasures and suggestions, such as implementing differentiated development strategy of urban modern agriculture, cultivating the awareness of win-win cooperation among cities, and deeply developing the multi-function of urban modern agriculture.

Key words: urban modern agriculture, win-win cooperation, Yangtze River Delta urban agglomeration
