Urban conceptual planning and urban strategic planning are non-statutory planning, and cities may or may not compile them.
In today's cities in China, urban conceptual planning and strategic planning are a kind of prediction and judgment for the long-term development of the city, which are generally given to the city through expert consultation. It provides a certain basis for the compilation of urban master plan.
In fact, strategic planning is usually a means for city governments to expand urban land use. Because the master plan needs the approval of the higher government, the land use is generally rigid. With the rapid development of the city, the city government needs a carrier to expand its territory and increase land use, and strategic planning can also play a role in avoiding the requirements of superiors in this regard.
Conceptual planning is equivalent to the conceptual planning of urban development, not quantitative but qualitative. For example, the discussion about the direction of urban development and so on. It provides a certain basis for the overall urban planning.
