Table 2.

List of the total supply and demand of land space in the development zone and the corresponding spatial ratio structure problems.

Serial number	Space type	Time	Supply and demand	Spatial proportion structure problem
1	Production space	3 months	Need < supply	Lack of agglomeration and low capacity
		9 months later	Need > supply	Excessive weight, inefficient development
2	Living space	3 months later	Need > supply	Housing is scarce and still vacant
3	Service space	3 months later	Need > supply	Service is scarce, center is missing
		3 months later	Need > supply	Low structure, lack of innovation
4	Overall space	3 months later	Need > supply	Lack of space, inefficient development
