Coupling coordination degree division standards and classification.

Coordination type	Coordination D range	Coordination level
Coordinated development	0.9< D ≤ 1	Quality Coordination
	0.8< D ≤ 0.9	Highly Coordination
	0.7< D ≤ 0.8	Moderate Coordination
Transitional development	0.6< D ≤ 0.7	Primary Coordination
	0.5< D ≤ 0.6	Barely Coordination
	0.4< D ≤ 0.5	Verge misaligned
Disorder decline	0.3< D ≤ 0.4	Mild Misaligned
	0.2< D ≤ 0.3	Mild Misaligned
	0.1< D ≤ 0.2	Severe Misaligned
	0< D ≤ 0.1	Extreme Misaligned
