Impact from EXTREME NATURAL DISASTERS on the Economic System Constituted by Two Factors, Three Departments and Four Categories of Residents——CGE Model Simulation

摘要：

A CGE model is built for the economic system constructed by two factors, three departments and four categories of residents and the impact effect of EXTREME NATURAL DISASTERS on this economic system is simulated by virtue of computer simulation. The fixed points of the economic system and the impact on distortion of general equilibrium of the economic system are computed by dint of MATLAB software and self-made program (genetic algorithm is adopted). Results: a EXTREME NATURAL DISASTERS may change the equilibrium price system (fixed points) of the economic system, the transaction costs of the economic system (in particular costs of property rights), residents maximum utility and the departments equilibrium quantity through influence on employment resource quantity, demand structure, production structure, residents real income and so on of the economic system. Conclusion: EXTREME NATURAL DISASTERS (Population and property damage) is the negative value production mechanism of the economic system with extreme high input-output rate.
