上海市三大产业CES生产函数弹性估计

Estimation of Elasticity of Substitution in CES Function of Major Industries in Shanghai

替代参数的合理估计是应用CES生产函数进行经济活动分析首要前提。而现有研究现有关于上海市三大产业生产函数替代参数的估计,使得后续研究缺乏必要的依据。本文以各统计年鉴中上海经济统计数据为基础,结合CES生产函数一阶优化条件式中的经济变量进行数据的处理,采用贝叶斯方法估计出CES生产函数假设下的上海市三大产业的替代弹性,从而为相关研究提供了可行的方法和可信的参数。

Reasonable estimation of elasticity of substitution is the premise of economical analysis with CES production function. However, there is seldom special study on substitution parameter estimation on Shanghai in available literatures, where applied researches based on CES production function are very difficult. We estimate elasticity of substitution in CES function of major industries in shanghai based on statistics reports about shanghai, with necessary data processing for first order condition of CES function and Bayesian estimation tool for small samples of available data in this paper, which provides feasible method and reliable parameters for relation studies.
