在运用景气指数法预警、计算扩散指数 DI和合成指数 CI时 ,往往存在警度不一致并导致警情失真等弊端 ,直接影响到景气评价的科学性 .在对传统 DI计算方法进行合理改进的基础上 ,引入精度比较的概念 ,选择精度更高的指数来进行景气评价 ,有效地消除了两指数 (DI与 CI )间的矛盾冲突 There are some shortcomings such as inconsistency of warning degree and distortion of police intelligence which often lead to the scientificalness of the evaluation of the economy when using the forecasting of the climate index method to calculate the diffusion index DI and the composite index CI.On the basis of rational improvement of the traditional DI calculation method, , The introduction of the concept of accuracy comparison, the choice of a higher index of accuracy for the assessment of the economy, effectively eliminating the conflict between the two indices (DI and CI)
