国内耦合协调度模型的误区及修正

Research on misuses and modification of coupling coordination degree model in China

随着对科学发展观认识的深入,耦合协调度模型成为研究区域整体均衡发展程度的有效评价与研究工具。但在该模型使用中,存在书写错误、丢失系数、错用权重和模型不成立四类误区,已经显著影响到学术研究的科学性。因此首先明确传统耦合协调度模型的规范公式,在探讨该传统模型在社会科学领域研究中效度问题基础上,进一步提出耦合度的修正模型。此外耦合协调度模型还存在指标构建的主观性、耦合结果的波动性和无可比性的信度问题。以京津冀生态与经济系统为例,验证修正后的耦合协调度模型具有较好的效度,研究对象的时空变化会显著影响耦合协调度模型的信度。

With the deepening understanding of the Scientific Outlook on Development,the coupling coordination degree model has become an effective evaluation and research tool for the regional overall balanced development.However,for this model,there are four types of misuses,including writing errors,coefficients loss,weight misuses and model failures,which have significantly affected the scientific nature of academic research.Therefore,this study firstly clarified the normative formula of the traditional coupling coordination degree model.On the basis of discussing the validity of the traditional model in the field of social science research,this study further proposed a modified model of coupling degree.In addition,the coupling coordination degree model has three reliability issues:the subjectivity of index construction,and the volatility and incomparability of coupling results.Taking the ecological and economic system of the Beijing-Tianjin-Hebei region as an example,we proved that the modified coupling coordination degree model has better validity,and the spatial and temporal changes of the research object will affect the reliability of the coupled coordination model.
