Abstract: To adapt to the new situation of urban and rural development, it is conditional and necessary for the pioneering areas of urban and rural integration in China to take the lead in changing the development concept and explore a higher level of urban-rural integration development path. Taking Suzhou, the pioneer of typical urban and rural integration practice, as an example, this paper points out the new connotation of a higher level of urban and rural integration in Suzhou under the background of the new era, that is, ‘mobility and barrier-free, integrable but no waste, various but no gaps’. The supply side reform is expected to boost the level of urban-rural integration from the three aspects of ‘institutional reform, factor innovation and supply transformation’, which constructs the development path of ‘reform of institutional supply and break through urban-rural barriers, integration of innovative elements and optimization of urban and rural structure, transformation of supply mode and activation of urban and rural value’, in order to provide a higher level of urban-rural integration in the pioneer areas of urban-rural integration development ideas.
