[Objective] This study aimed to examine the simulated effect of Computable General Equilibrium （CGE）-based agricultural policy simulation system. [Method] The policy simulation platform based on CGE model was constructed by integrating policy simulation, CGE model and Decision Supporting System （DSS）. The scenario analysis method was used to analyze the agricultural subsides policy simulation through empirical analysis. [Result] Farmers were the main beneficiaries of increasing agricultural production subsidies, which increased farmers＇ income and improved the export of agriculture products. The prototype system could solve the problems in actual policy simulation. [Conclusion] The results lay the foundation for the quantitative study on agricultural subsidy policy in China.
针对目前政策模拟分析系统缺乏的问题,提出利用计算机技术将CGE模型、DSS、数据仓库、数据转换等集成在一个模拟系统中:采用Visual C++.net开发模拟分析系统的人机交互界面和问题处理系统;GAMS IDE完成CGE模型生成和求解系统;数据仓库采用SQL Server 2000设计并实现,构造了政策模拟原型系统。在所设计的模拟系统上,以农业补贴政策模拟为例,通过情景分析法进行实证模拟分析。结果表明:模拟集成系统初步实现了CGE建模、模拟计算、系统维护及人机交互的功能。该模拟系统能够解决实际政策模拟问题,辅助决策者进行政策制定。
[目的]针对定量研究国内农业补贴政策的需要,探讨基于可计算一般均衡模型(Computable General Equilibrium,CGE)的农业政策模拟系统模拟效果。[方法]将政策模拟、CGE模型以及DSS决策系统进行集成研究,构造一个基于CGE模型的政策模拟系统平台,并在所设计的模拟平台原型中,通过情景分析方法对农业补贴政策模拟进行实证分析。[结果]农业生产补贴的上调主要收益者是农民,增加了农民收入,提高了农业产品的出口;模拟系统在一定程度上能够解决实际政策模拟问题。[结论]该研究结果为国内农业补贴政策的定量研究奠定了基础。
