Agricultural Policy Simulation Based on Computable General Equilibrium Model
[Objective] 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 subsidies policy simulation with examples in the prototype of the designed policy simulation platform.[Result] The main beneficiaries of increasing agricultural production subsidies are farmers,increasing farmers' income and improving the export of agriculture products.The prototype system can solve the problems in actual policy simulation.[Conclusion] The results laid the foundation for the quantitative study on agricultural subsidy policy in China.
Abstract Necessary conditions and iterative computational algorithms are obtained for the problem of choosing feedback gains to optimize a linear control system with a quadratic cost function. The results are obtained in abstract terms and cover a wide range of practical problems. A design example is given
