Network development theory is the extension of point axis development theory. According to the theory, after economic development to a certain stage, a region has formed growth poles, that is, all kinds of central cities and towns and growth axis, that is, along the transportation lines. The influence scope of growth poles and growth axes is constantly expanding, forming a flow network of production factors such as goods, capital, technology, information, labor force, and transportation and communication networks in a larger region. On this basis, the network development theory emphasizes to strengthen the breadth and density of the exchange of production factors between the growth pole and the whole region, so as to promote the regional economic integration, especially the integration of urban and rural areas; at the same time, through the extension of the network, it strengthens the connection with other regional economic networks outside the region, and reasonably allocates and optimizes the combination of more production factors in a larger space, To promote economic development in a larger region. The theory of network development should be applied in economically developed areas. As the theory focuses on promoting the integration of urban and rural areas, its application is more conducive to gradually narrowing the differences between urban and rural areas and promoting the coordinated development of urban and rural economy.<br>
