摘要
采用类比方法构建出一种面板数据曲线的棱镜模型,把时间横坐标与经济问题纵坐标加以角度化变换,选取恰当的经济变量作为棱镜的折射率和顶角,可将面板数据曲线用棱镜曲线进行再描绘.在碳排放问题上,列举大量的面板数据曲线作为具有棱镜曲线形状的证据,并给出聚类分析,解决了棱镜模型的应用问题,得出了存在经济折射定律的观点结论,从而为应用经济学研究提供一种全新视角的分析工具.
A prism model of panel data curve is constructed by analogy method. Choosing economic variable as prism apex angle and refractivity, changing year abscissa and economic issue vertical ordinate tune to angles, the panel data curves can be redrawn by prism curves. On the issue of carbon emission problem, a large number of panel data curves is listed as evidence of the prism curves shape, and the clustering analysis is given. A view that there is the law of economic refraction is proposed, which provides a new angle of view for the research on applied economics analysis tools.
