“計量模型多樣性悖論”研究
發(fā)布時間:2018-08-30 13:23
【摘要】:在排除模型誤用以后,將經(jīng)濟學研究中針對同一問題的研究,不同計量模型的結果各不相同,甚至結論截然相反問題稱為"計量模型多樣性悖論"。分析此問題產(chǎn)生的原因,主要是關鍵變量的多樣性、方程形式設定的多樣性和計量模型的多樣性,提出采用元分析來解決這個問題,指出在元分析應用過程中應力求單個模型的精確,盡可能多地采用合適的模型,注意同類性質的結果才能進行元分析。同時,討論元分析帶來的新問題,比如對研究團隊的計量經(jīng)濟學水平要求較高,增加了成本,延長了研究的時間,也加大了論文的篇幅等,但這是計量經(jīng)濟學發(fā)展過程中的正,F(xiàn)象,并不涉及采用元分析解決"計量模型多樣性悖論"問題的科學性。
[Abstract]:After eliminating the misuse of the model, the results of different econometric models are different for the same problem in the study of economics, and even the opposite problem is called "the paradox of econometric model diversity". This paper analyzes the causes of this problem, mainly the diversity of key variables, the diversity of equations and the diversity of measurement models, and puts forward a meta-analysis method to solve this problem. It is pointed out that in the application of meta-analysis, we should strive for the accuracy of a single model, adopt as many suitable models as possible, and pay attention to the results of similar properties before we can carry out meta-analysis. At the same time, it discusses the new problems brought by meta-analysis, such as the high level of econometrics required of the research team, the increase of cost, the prolongation of the research time, and the length of the thesis, etc. However, this is a normal phenomenon in the course of econometrics development and does not involve the scientific nature of solving the problem of "econometric model diversity paradox" by meta-analysis.
