耦合协调度模型的修正与改进
Modification and Improvement of Coupling Coordination Degree Model
摘要
Abstract
With the deepening of social science research,coupling coordination degree model has become an important eval-uation tool for regional coordination development research.But with the widespread application of the model,problems are gradu-ally revealed.In order to increase the discrimination of the coupling coordination degree model,solve the calculation boundary problem in traditional models,and correctly reflect the essential meaning of coupling coordination,this paper constructs an im-proved coupling coordination degree model based on the connotation of coupling coordination degree,proposes that coupling coor-dination degree should be graded with equal probability,and improves the classification table by kernel density estimation and Monte Carlo method.The new grading table corrects the judgment bias of the traditional grading table that the change of coupling coordination level is more stable,and considers the probability distribution of coupling coordination degree under different system numbers.Through empirical comparison,it is found that the improved coupling coordination degree model and grading table are more suitable for coupling coordination evaluation in the field of social science than the traditional model and grading table.关键词
