Abstract: Using basic theory of economic input-output analysis, sets up an input-output mathematical model to explore the impact of climate change on regional economy. This model combines with the models of climate change on agriculture and industry products.The research provides such a framework for climate impact analysis that can reflect the interactions among different sectors. individual and whole economic sectors. It can illustrate the nature of interrelationships among these economic sectors and between regions,also it incorporates climate change factors into the economic input-output analysis. With regard to natural and social status and economy developing scale and speed, the structure and proportion of the future first, second, third property, coefficients of the model are adjusted, the economic development in 2010.2020 is predicted considering various impacts associated with climate change on agriculture and industry. Then we propose some adaptation countermeasures of climate change to the decision-making department for future developing policy.
