Coordinated Development of Population, Resources, Environment, Economy, and Society under Engineering Management Combined with Bilevel Optimization Model

Table 3

Settings of the relevant parameters in the stage mode.

Classification	Degree of coordinated development	Level 1 criteria	Level 2 criteria
Interval of coordinated development	0.9∼1	Superior coordination	① When m = min{/(x), , h(z)}, it is a lagged type, similar to m = /(x), which is population lagged type.; ② When/(x) =  = h(z), it is a synchronous type for population, economy, and environment
	0.80∼0.89	Good coordination
	0.70∼0.79	Moderate coordination
Interval of transitional reconciliation	0.60∼0.69	Basically coordinated
	0.50∼0.59	Barely coordinated
	0.40∼0.49	On the verge of dysfunction and decline
Interval of dysfunction and decline	0.30∼0.39	Mild dysfunction and decline
	0.20〜0.29	Moderate dysfunction and decline
	0.10∼0.19	Severe dysregulation and decline
	0∼0.09	Extremely severe dysfunction and decline

Note: low, medium, and high stand for high growth rate, medium growth rate, and low growth rate, respectively. The parameters of the province are set based on the “12th Five-Year Plan”; the plan refers to the leapfrog plan of the key advantageous industries in the province, the establishment industry development plan of the province, the establishment industry development plan of the province in 2013, and the studies by scholars such as Lin Fude and Fu Jiafeng.
