经济学家们一直在挖掘能解释经济过去运行的轨迹、预测经济未来发展的模型和方法,基于各种假设的模型也在这个过程中不断被继承和推翻。随着理论和技术的发展,经济学家们不断从各个角度,对资本、劳动力、资源这三个经济发展中最基础的三大要素,估计经济发展的影响和作用。从开始的线性回归,到现在被频繁使用的面板数据;从外生经济理论,到内生经济理论,经济增长理论的研究虽然取得了成果,但是仍存在许多亟待弥补的缺陷。

From the beginning of the linear regression to the nowadays panel data that is used frequently; the research from the exogenous economic theory, the endogenous economic theory and the economic growth theory has made some achievements, but there are still many shortcomings to be remedied.
