【摘要】：本文基于江苏省十三市经济与环境数据,对目前运用广泛的协调度模型进行分析并建立改进模型,借助改进后的模型计算十三市的经济环境协调度并对比,以提出经济与环境协调发展的设想。本文首先建立江苏省各市经济发展与环境质量的指标体系,借助主成分分析解决指标间的权重问题,将主成分得分作为新的数据带入模型以简化运算过程。对已有协调度模型进行评估后,基于多维效用并合模型的思想对模型进行修正,生成新的协调度模型。新模型能兼顾子系统的绝对发展程度和相对发展差距,消除了其他模型只能考虑其中一方或存在特殊情况的缺陷。混合模型灵活度高,适用于能透彻理解被研究系统、能准确定义参数的情况;距离规则模型适用于无法确定使用何种模型的情况,在信息较少的前提下准确程度较高。最后,借助新模型获得江苏十三市经济环境发展协调度排名,通过对比分析论证模型的可靠性并提出江苏省经济发展与环境质量协调发展的设想。
[Abstract]:Based on the economic and environmental data of 13 cities in Jiangsu Province, this paper analyzes the widely used coordination degree model and establishes an improved model. With the help of the improved model, the economic and environmental coordination degree of 13 cities is calculated and compared. In order to put forward the idea of coordinated development of economy and environment, this paper first establishes the index system of economic development and environmental quality in Jiangsu Province, and solves the weight problem among the indexes by means of principal component analysis (PCA). The principal component score is introduced into the model as a new data to simplify the operation process. After the evaluation of the existing coordination degree model, the model is modified based on the idea of multi-dimensional utility combination model. The new model can take into account the absolute degree of development of the subsystem and the relative development gap, and eliminates the defect that other models can only consider one of them or the existence of special circumstances. Suitable for situations where the system under study can be thoroughly understood and parameters can be accurately defined; the distance rule model is suitable for situations where it is not possible to determine which model to use, and is more accurate with less information. Finally, With the help of the new model, the rank of coordination degree of economic and environmental development in 13 cities of Jiangsu Province is obtained. The reliability of the model is analyzed and the assumption of coordinated development between economic development and environmental quality of Jiangsu Province is put forward.
