The 19 th CPC National Congress proposed a strategy of rural revitalization, giving priority to the development of "sannong" to promote the modernization of agriculture and the countryside. Since China's reform and opening up, Southern Jiangsu has experienced rapid urbanization and industrialization along with the development of township and village industries, making its urbanization rate reaching 75.9%. While significant achievements have been made in urban and rural development, there are still many challenges in rural revitalization. Based on analysis on the characteristics and problems of rural development in Southern Jiangsu, this paper, aiming at rural revitalization, puts forward methods and paths of rural revitalization, such as value cognition, layout optimization, industrial revitalization, ecological livability, and rural governance, which are of practical significance to promote the integrated urban-rural development and the healthy rural development in the region and to provide a reference of rural development for other areas of the country.展开更多
